The Seattle Mariners are an American professional baseball team based in Seattle. The Mariners compete in Major League Baseball (MLB) as a member club of the American League (AL) West Division. The team joined the American League as an expansion team in 1977, originally playing their home games in the Kingdome. Since July 1999, the Mariners' home ballpark has been T-Mobile Park, located in the SoDo neighborhood of Seattle.

Key Information

The "Mariners" name originates from the prominence of marine culture in the city of Seattle. They are nicknamed the M's, a title featured in their primary logo from 1987 to 1992. They adopted their current team colors – navy blue, northwest green (teal), and silver – before the 1993 season, after having been royal blue and gold since the team's inception; the original colors continue to be used in alternate uniforms. Their mascot is the Mariner Moose.

The Mariners did not field a winning team until 1991, and further success eluded them until the late 1990s, the most successful period in franchise history. Led by Hall of Fame players Edgar Martínez, Ken Griffey Jr., and Randy Johnson, the Mariners clinched their first playoff berth in 1995 when they won their first division championship and defeated the New York Yankees in the ALDS. Martínez's walk-off double in Game 5 drove Griffey in from first base to win the game in the 11th inning, clinched a series win for the Mariners, served as a powerful impetus to preserve baseball in Seattle, and has become an iconic moment in team history. They would win their second division title in 1997.

After Griffey, Johnson, and Alex Rodriguez left the team, the Mariners, bolstered by the signing of Ichiro Suzuki, won 116 games in 2001, which set the American League record for most wins in a single season and tied the 1906 Chicago Cubs for the Major League record for most wins in a single season. The team would not make the postseason again until 2022, breaking the longest active drought in the four major North American sports. They won their fourth AL West division title in 2025, their first title since 2001.

The franchise has finished with a losing record in 30 of 49 seasons, as of 2025. The Mariners are the only active MLB franchise to never appear in the World Series, holding the sport's longest active World Series appearance drought.

As of the end of the 2025 season, the Mariners' all-time win–loss record is 3,689–4,022–2 (.478).[5]

History

[edit]
Main article: History of the Seattle Mariners

The Mariners were created as a result of a lawsuit. In 1970, after Bud Selig bought the Seattle Pilots and moved them to Milwaukee to become the Milwaukee Brewers, the city of Seattle, King County, and the state of Washington (represented by then-state Attorney General and future U.S. Senator Slade Gorton) sued the American League for breach of contract.[6] Confident that Major League Baseball would return to Seattle within a few years, King County built the multi-purpose Kingdome, which would become home to the National Football League's expansion Seattle Seahawks in 1976.[7] The name "Mariners" was chosen by club officials in August 1976 from more than 600 names submitted by 15,000 entrants in a "name the team" contest. The name was submitted by Roger Szmodis of Bellevue, Washington. When the Mariners attempted to reach Szmodis about the prize he had won, they were unsuccessful—initially and ultimately.[8][9]

Ken Griffey Jr. holds six single-season batting records and an individual career record for the Mariners franchise.

The first home run in team history was hit on April 10, 1977, by designated hitter Juan Bernhardt.[10]

That year, pitcher Diego Seguí, in his last major league season, became the only player to play for both the Pilots and the Mariners. The Mariners finished with a 64–98 record, matching the 1969 Pilots' record. The team avoided finishing in last place in the AL West by half a game. The Mariners would not post a winning record or finish above 4th place in any of their first 14 seasons. In 1979, Seattle hosted the 50th Major League Baseball All-Star Game. After the 1981 season, the Mariners were sold to California businessman George Argyros,[11] who in turn sold the team in 1989 to a group led by Indianapolis-based Jeff Smulyan, who owned radio and television stations, for $76 million. Smulyan proposed moving the team to Tampa, Florida or another market in 1992 before he put the team up for sale.[12][13] Nintendo of America bought the team in 1992; Nintendo CEO Hiroshi Yamauchi, who held a 49 percent share of the franchise, had never been to a baseball game but sought to thank the city for its role in the company's success.[14][15]

Before the 1993 season, the Mariners hired manager Lou Piniella, who had led the Cincinnati Reds to victory in the 1990 World Series. Mariners fans embraced Piniella,[16] and he would helm the team from 1993 through 2002, winning two American League Manager of the Year Awards during his tenure. (Piniella was selected by the Pilots in the 1968 expansion draft but did not play for Seattle, being traded in April 1969 to the Kansas City Royals, where he earned AL Rookie of the Year honors that year.)

The Mariners first won the AL West and made the playoffs in 1995, despite star outfielder Ken Griffey Jr. missing much of the season after breaking his wrist crashing into the center field wall.[17] The team defeated the California Angels in a one-game playoff to win the division.[18] The Mariners returned to the playoffs in 1997 and 2000.[19]

The 2001 Mariners finished with a record of 116–46, leading all of Major League Baseball in winning percentage for the duration of the season and easily winning the American League West division title. In doing so, the team broke the 1998 New York Yankees' American League single-season record of 114 wins and matched the all-time MLB single-season record for wins set by the 1906 Chicago Cubs.[20] At the end of the season, Ichiro Suzuki won the AL MVP, AL Rookie of the Year, and one of three outfield Gold Glove Awards, becoming the first player since the Fred Lynn in 1975 to win all three in the same season.[21] The Mariners advanced through the postseason but lost to the Yankees in the 2001 ALCS.[22] It would be the team's last playoff appearance until 2022.[19][23]

The Mariners had a 93-win season in 2002 but failed to make the postseason. Manager Lou Piniella was traded to the Tampa Bay Rays during the offseason. The team repeated with 93 wins in 2003 and also did not qualify for the playoffs.[22] On October 22, 2008 the Mariners announced the hiring of Jack Zduriencik, formerly scouting director of the Milwaukee Brewers, as their general manager.[24] Weeks later, on November 18, the team named Oakland Athletics bench coach Don Wakamatsu as its new manager. The off-season also saw a litany of roster moves, headlined by a 12-player, 3-team trade that sent All-Star closer J. J. Putz to the New York Mets and brought 5 players, including prospect Mike Carp and outfielder Endy Chávez from New York and outfielder Franklin Gutiérrez from the Cleveland Indians, to Seattle. Many of the moves, like the free-agent signing of Mike Sweeney, were made in part with the hope of squelching the clubhouse infighting that plagued the Mariners in 2008. It also saw the return of Seattle favorite Griffey Jr.[25] The 2009–10 offseason was highlighted by the trade for 2008 AL Cy Young Award winner Cliff Lee from the Philadelphia Phillies, the signing of third baseman Chone Figgins, and the contract extension of star pitcher Félix Hernández.[26][27][28]

Inside the Kingdome (1977–June 1999)

Griffey Jr. announced his retirement on June 2, 2010, after 22 MLB seasons.[29] After its busy offseason and high expectations, the team flopped in 2010, finishing with the worst record in the American League. The Mariners fired Wakamatsu along with several coaches on August 9, 2010. Daren Brown, the manager of the Triple-A affiliate Tacoma Rainiers, took over as interim manager.[30] Dave Niehaus, the Mariners' play-by-play announcer since the team's inception, died of a heart attack on November 10, 2010, at the age of 75.[31] In memory of Niehaus, Seattle rapper Macklemore wrote a tribute song called "My Oh My" in December 2010. He performed the song at the Mariners' Opening Day game on April 8, 2011.[32] The Mariners hired former Cleveland manager Eric Wedge as their new manager on October 19, 2010.[33]

On April 21, 2012, Philip Humber of the Chicago White Sox threw the third perfect game in White Sox history against the Mariners in Seattle. It was the 21st perfect game in MLB history.[34] Mariners starter Kevin Millwood and five relievers combined to throw the tenth combined no-hitter in MLB history, the first in Mariners history, on June 8. The six pitchers used in a no-hitter tied a major league record, first set by the Houston Astros in 2003. Félix Hernández pitched the first perfect game in team history, shutting down the Tampa Bay Rays 1–0 at Safeco Field on August 15. It was the 23rd perfect game in Major League Baseball history.[35] The Mariners became the first team in Major League Baseball to be involved in two perfect games in one season.[36]

Zduriencik was fired on August 28, 2015. Jerry Dipoto, a former general manager of the Los Angeles Angels of Anaheim, was hired as the Mariners' new general manager one month later.[37] On October 9, manager Lloyd McClendon was fired.[38] Scott Servais was named the new Mariners' manager on October 23.[39]

Nintendo announced on April 27, 2016, that it would sell its controlling stake in the Mariners to First Avenue Entertainment limited partnership, led by John W. Stanton. Nintendo retained a 10 percent ownership share of the team after the sale was completed in August 2016. The franchise was valued at $1.4 billion at the time and included Root Sports Northwest, the team's regional television network.[12][40]

The Stanton/Dipoto/Servais era was characterized by two competitive phases. In the first phase, the organization tried to contend for a championship with the existing core of Robinson Cano, Félix Hernández, Nelson Cruz, and Kyle Seager. The team came close but ultimately missed the playoffs. Following the 2018 season, the organization pivoted to a rebuild, trading several players for prospects. Following a fallow period of 2019–20, the team returned to contention in 2021, winning 90 games but falling short of the playoffs. In 2022, with a new core including Julio Rodríguez, J. P. Crawford, Cal Raleigh, Luis Castillo, George Kirby, and Logan Gilbert, the team reached the postseason for the first time since 2001. This broke what was at the time the longest playoff drought of any team in the "Big Four" North American sports.[41][42] Rodríguez also won the American League Rookie of the Year Award. In 2023, the team won 88 games but finished one game out of a playoff spot. In August 2024, Servais was fired after blowing a 10 game lead in the AL West over the Houston Astros and having the team fall back to .500. Servais was replaced by the team's former catcher Dan Wilson as manager.[43] The team again missed the playoffs by one game. In 2025, the Mariners won their first AL West title since 2001. The 2025 Season marks the closest the Mariners have ever been to the World Series.[44]

Uniforms

[edit]

1977–1980

[edit]

The Mariners' original colors were blue and gold, the color scheme previously used by the Seattle Pilots and its successor Milwaukee Brewers. For the first four seasons, they wore white pullover jerseys at home with the team name in front and numbers on the left chest. The "M" in "Mariners" was shaped to resemble a trident. On the road, they wore baby blue pullover jerseys with the city name in front and numbers on the left chest. The lettering colors were blue with gold trim, though in the 1977 season the trim on the road jersey was white and the "Seattle" wordmark appeared smaller. The trident logo was added to the left sleeve prior to the 1979 season.

The cap was all-blue and featured the gold trident logo with white trim.

[edit]

The Mariners made some subtle changes to the uniform in 1981. The trident logo was replaced by blue and gold racing stripes on the shoulders, and the lettering received an extra blue outline. The number font also changed from rounded to block style. In 1985, the road jersey color was changed to grey.

The cap logo also featured a slight update of the trident logo, changing its color to blue, along with additional outlines and a white star background, a logo first used for the 1979 All-Star Game.

1987–1992

[edit]

In 1987, the Mariners changed its uniform style to traditional buttoned tops and belted pants. Both uniforms incorporated blue piping and a block "Mariners" wordmark in blue with gold and blue outlines. The numbers remained blue, but eliminated the trim outlines.

The cap logo was changed to a gold "S."

1993–present

[edit]

The Mariners donned their current uniforms in 1993. The white home uniform originally featured "Mariners" in navy with trim in a shade of teal green, exclusively named "Northwest Green" for the team, and featured the "compass rose" logo atop the "M."[45] The grey road uniform originally featured "Seattle" in navy with Northwest Green and white trim; in 2001, the compass rose logo was added in the middle of the "S." In 2015, a silver inline was added to the wordmark of both uniforms, which was also applied to the block letters and numbers. The primary logo is applied to the left sleeve.[46]

From 1997 to 2000, the Mariners also wore sleeveless versions of their primary uniforms, accompanied with a navy undershirt.

The Mariners have also worn Northwest Green alternate uniforms at different points in their history. The original version was unveiled in 1994 and had "Mariners" in silver with navy and white trim. The next season, the white trim was removed[47] to improve visibility. The Mariners did not wear green uniforms from 1997 to 2010, after which it became a regular part of their uniform rotation. Formerly worn on Friday home games, the Northwest Green alternates are currently worn on select Saturday home games and on road games in which the home team wears either navy or black uniforms.[48][49]

The navy alternate uniform originally replaced the Northwest Green alternate in 1997 and featured the team name in silver with Northwest Green and navy trim. In 1999, the alternates were updated to feature the city name with the "S" behind the compass rose logo and silver piping; this became their road alternate the following season after a corresponding home navy alternate was introduced. In 2003, the silver piping was removed and the letter and number fonts were changed to match the wordmark. In 2012, after the Northwest Green home alternates were brought back, the navy uniforms were tweaked anew, this time with the city name in front and stylized serifed letters instead of the normal block letters. In 2024, the names were changed to block lettering. It is now worn on most road games, though they have also donned them at home on occasion.

A navy blue cap that features a ball and compass rose "S" logo is paired with the home white, road gray, and navy blue jerseys. A variation of this cap with a Northwest Green brim is worn with the home alternate jersey. In 1994, the Mariners also wore Northwest Green caps with navy brims, and in 1997 the team wore a navy cap with grey brims.

In January 2015, the team announced a new alternate uniform to be worn for Sunday home games. This cream-colored "fauxback" uniform features the current logo and lettering style in a royal blue and gold color scheme, a throwback to the original team colors. Unlike the rest of the uniform set, the back of the jersey does not display the player name.[48][1] The cap features the current cap logo in the throwback colors.[1][50]

In January 2019, the Mariners announced a new home and away uniform to be worn during spring training. The jersey has a design similar to their home white jerseys but features a powder blue throwback to the team colors during the 1980s. The cap has the usual navy blue color, but with a logo that features the signature compass rose and with a large M in the center.

For the 2023 season, MLB and Nike have instituted a "four plus one" model for team uniforms, consisting of a home uniform, away uniform, two alternate uniforms, and a City Connect uniform featuring "color schemes and logos that pay homage to a team's city."[51] The Mariners confirmed that they will replace the gray jerseys with the navy blue jerseys as their standard away uniforms for the 2023 season.[52][53] The team will also stop using the powder blue jerseys during spring training.[52] The choice to remove the gray and powder blue jerseys was based on feedback from players and fans, according to Kevin Martinez, the Mariners senior vice president of marketing and communications.[53]

The Mariners' City Connect uniform is a visual nod to Seattle's baseball history. The jersey includes a sleeve patch featuring Mount Rainier and the letters "PNW," an acronym for Pacific Northwest. The jersey also includes the inaugural colors of the team and the word "Seattle" across the chest lettering reminiscent of the Seattle Pilots. The jersey is paired with a cap that has new design of the trident logo and black pants. This uniform is primarily worn during Friday home games.[54] The team wore the City Connect uniform more frequently in 2024, since they won most of their games in the alternates.[55] In the 2025 season, the Mariners partnered with Nintendo of America to have the Nintendo “racetrack” logo on the sleeve of the home game jersey and the logo of Nintendo on the sleeve of the away game jersey.[56]

Spring training

[edit]

The Peoria Sports Complex in Peoria, Arizona has been the Mariners' home spring training facility since 1994. The complex is shared with the San Diego Padres.[57] On March 25, 2013, in a 16–0 victory over the Cincinnati Reds, the Mariners broke the team record for total home runs during a spring training season with 52.[58]

Seattle Mariners Hall of Fame

[edit]
Main article: Seattle Mariners Hall of Fame

Mariners then-chairman and CEO John Ellis announced on June 14, 1997, the creation of a Mariners Hall of Fame. The Mariners operate the hall of fame, which honors players, staff, and other individuals that greatly contributed to the history and success of the Mariners franchise. It is located at the Baseball Museum of the Pacific Northwest in T-Mobile Park.[66] The most recent Mariners Hall of Fame member, Félix Hernández, was inducted August 12, 2023.[67]

The Mariners criteria for retiring a uniform number is more selective than the standards for the Mariners Hall of Fame. To be eligible to have one's number retired, in addition to the criteria outlined for the Mariners' Hall of Fame, the former Mariners should have either:
      a) been elected to the National Baseball Hall of Fame and been in a Mariners uniform for at least five years, or
      b) come close to such election and have spent substantially his entire career with the Mariners.
Eligibility shall not commence until after the former player has been voted on once for the National Baseball Hall of Fame, which for effectively means six years after retirement.[70]

Ken Griffey Jr.'s No. 24 was retired at the beginning of the 2016 season, with the retirement ceremony taking place on August 6, 2016.[71][72] Griffey was elected to the Hall of Fame in January of that year.

Edgar Martínez's No. 11 was retired during the 2017 season, with the retirement ceremony taking place on August 12, 2017. Martínez played his entire career with the Mariners and first appeared on the Hall of Fame ballot in 2010. His No. 11 was retired in 2017, predating his 2019 election to the Hall of Fame and seemingly establishing the 58.6% of the vote he received that year as sufficiently "close" to election to satisfy the criteria.[73][74] The number 11 was not issued to anyone after Martínez's retirement as a player in 2004 until his return to the Mariners as hitting coach in 2015.[75]

Ichiro Suzuki's No. 51 was retired by the Mariners in a pregame ceremony on August 9, 2025, days after his induction into the Hall of Fame.[76] He has continued to wear the number after retiring, including during spring training in 2020 and 2022 as well as when throwing out a ceremonial first pitch in 2022.[77][78][79]

Jackie Robinson's No. 42 was retired throughout MLB on April 15, 1997, the 50th anniversary of him breaking MLB's racially exclusionist color line.[80]

Randy Johnson is also scheduled to have his No. 51 retired by the Mariners in 2026. Johnson played 10 seasons with the Mariners, from 1989 until mid-1998, and was elected to the Hall of Fame in 2015. The #51 was withheld until 2001, when it was issued to Ichiro Suzuki upon his request. No other player, besides Suzuki, has worn that number for the Mariners since Johnson. On June 2, 2025, the Mariners announced they will also retire 51 in honor of Johnson in 2026, however the date has yet to be released, and is set to be released once the schedule for the 2026 season is finalized.[81]

[edit]

From the 1990 season through the 2021 season, as part of the seventh-inning stretch, after the crowd was led in singing "Take Me Out to the Ball Game" or "God Bless America" the public address system played the Kingsmen's version of "Louie Louie". The song was a regional hit in the Northwest, covered by many local bands for nearly a decade until the Portland-based Kingsmen recorded their version in 1963. In 1985, the song's regional importance was publicized by a campaign to make it the official state song of Washington. The tradition to play the song during the seventh inning stretch began as an attempt for the then new ownership group to put its stamp on the team, and was solidified on June 2, 1990, when the Kingsmen performed the song in the middle of the seventh inning live from atop a dugout. That game, Randy Johnson threw the first no-hitter in Mariners history.[82][83]

For the 2022 season, the Mariners replaced "Louie Louie" with the Macklemore & Ryan Lewis song "Can't Hold Us". Replacing "Louie Louie" was a source of contention for some fans.[84] The Mariners stopped playing "Can't Hold Us" after Macklemore's comments at a Palestinian benefit concert in September 2024.[85]

'Louie Louie' returned to games in the 2025 season, remixed to a slightly more uptempo beat and interspersed with encouragement to the crowd ("Let's Go Mariners!"). [86]

Buhner Buzz Cut Night

[edit]

In 1994, the Mariners started a promotion called "Buhner Buzz Cut Night." Inspired by Jay Buhner's shaved head, any fan who was willing to have their head shaved before the game—or was already bald—would receive a free ticket to the game and a T-shirt with a slogan, such as "Bald Is Buhnerful" or "Take Me Out to the Bald Game". Hair 10 inches or longer was collected for charity. The promotion continued until Buhner's retirement in 2001, with a year's hiatus in 2000, and is still remembered by fans today. The club revived the promotion for its 30th anniversary in 2024, with Buhner giving catcher Cal Raleigh a buzz cut.[87]

Rally Fries

[edit]

Rally Fries are a baseball tradition started by Mariners broadcaster Mike Blowers in 2007. During a game against the Cincinnati Reds, a fan tried to catch a foul ball along the right-field line but in turn spilled his tray of french fries along the track. While chatting on the air and seeing the mishap, Blowers's partner, Dave Sims, suggested that he should send a new tray of fries to the fan. Blowers agreed, and sent his intern to deliver a plate of fries to the man.[88]

At the Mariners' next game, fans made signs and boards asking Blowers for fries as well. Coincidentally, every time the fries were delivered, the Mariners seem to score or rally from a deficit, and thus the "Rally Fries" were created. This became so popular with the fans that signs were even seen when the Mariners were the visiting team, although on August 1, 2009, Blowers established that he only gives out fries at home games.[89]

Generally, Blowers would select a person or a group of people that appealed to him, whether it was through fans wearing elaborate costumes or waving funny signs and boards. The fries were usually delivered from Ivar's, a Seattle-based seafood restaurant with a location at T-Mobile Park. The amount of fries given out varied with the size of the winning group of fans. The winners were generally selected around the 5th or 6th inning, although potential candidates were shown in almost every inning beforehand.

Sims confirmed in 2012 that the Rally Fries promotion had ended.[90]

JROD Squad

[edit]

The JROD Squad honors Mariners center fielder Julio Rodríguez. The location varies, although it is usually in seats in center field. Fans buying tickets to the JROD Squad section (referred to collectively as JROD's Squad) receive a T-shirt showing a replica of a gold chain Rodríguez wears around his neck.[91] Rodríguez often interacts with the JROD Squad, waving to them and throwing them balls at the end of innings.

Previous fan sections

[edit]

Area 51

[edit]

When Ichiro Suzuki played right field for the Mariners, seats in right field were often informally called Area 51, a nod to Suzuki's uniform number (51) and the top-secret government site in Nevada of the same name.[92][93]

King's Court

[edit]

As the 2011 season progressed, the Mariners' marketing staff came up with an idea to encourage the growing fanbase of star pitcher "King" Félix Hernández. Every Hernández start at T-Mobile Park was accompanied by the King's Court, a designated cheering section for fans to sing, chant, and cheer while donning yellow T-shirts and "K" cards supplied by the team. It was located in the lower seating area along the third baseline.[94] The team encouraged other activities, such as dressing like Larry Bernandez, Hernández's alter ego from a Mariners TV commercial, and awarding fans wearing costumes with a turkey leg.[95]

The Supreme Court was a special event where the King's Court section was extended to the entirety of T-Mobile Park. The first Supreme Court was Hernández's first home game following his perfect game in 2012.[96] Following opening day 2012, it occurred each year at Hernández's first home game of each season.

The King's Court ended following Hernández's departure from the Mariners at the end of the 2019 season.[97]

Maple Grove

[edit]

During the 2017 season, fans created the Maple Grove, a celebration of Canadian pitcher James Paxton and inspired by the King's Court. At home games where Paxton started, a group of fans sat under a Maple Grove banner, typically in the left-field bleachers. A potted maple tree was also present in their section, provided by the Mariners. The Grove dubbed the tree "Stick Rizzs," referencing long-time broadcaster Rick Rizzs.[98][99]

When Paxton got to two strikes on a batter, the Grove held up “Eh” Cards, a tip of the cap to Paxton's home country of Canada and a nod to the "K" (for strikeout) cards held up in King's Court.[98] Variant cards have also been produced for special occasions, such as when a planned Paxton start turned into a Hernández start (a King's Grove, with "K'eh" cards to cheer for Hernández). Other special cards celebrated Paxton reaching 300 strikeouts, and a tribute to broadcaster Angie Mentink ("A" cards, to show support after she had publicly disclosed her breast cancer diagnosis). An "Eh" card is now part of the Baseball Hall of Fame's collection.[100]

The Maple Grove differed from the King's Court in that it was created and organized by fans, while the Court was promoted by the Mariners' marketing team. When asked, Paxton stated that fans creating the Maple Grove was really special to him and that he never imagined that something of the sort would ever be done for him.[101] The Grove continued until Paxton was traded to the Yankees following the 2018 season.[102]

Rivalries

[edit]

Divisional

[edit]

The Mariners also held a longstanding divisional rivalry with the Oakland Athletics as they would often battle for playoff contention or lead of the division through the early 2000s. Following the realignment of the division in 2013, the Mariners have also built a recent rivalry with the Houston Astros as both teams have handily fought for control of the division.[103][104]

Los Angeles Angels

[edit]

The Los Angeles Angels have maintained an off-and-on rivalry with the Mariners as both teams have often fought for control of the division or a playoff berth. Both teams often clashed for playoff positions during the early 2000s as the Mariners boasted a 116 win team in 2001 while the Angels managed to win the World Series in 2002. Despite both teams encountering a decline through the decade, regular matchups often developed into clashes for relevance in the division. Recently, both teams were each trying to end postseason droughts, bolstered by players such as Julio Rodríguez and Ty France for Seattle and Shohei Ohtani and Mike Trout for the Angels[105][106] The two teams have met 741 times, with the Angels leading the series 400–341. The teams have yet to meet in the postseason.[107] In 2022, tensions were heightened after Angels pitcher Andrew Wantz intentionally hit Mariners batter Jesse Winker with a pitch, leading to a major brawl that resulted in several players receiving suspensions.[108]

Houston Astros

[edit]

The Mariners and Houston Astros have fought for control of the division in recent years, since the Mariners started periodically contending for the postseason in 2014. The Astros lead the all-time regular season series 132–97 and have a perfect 3–0 record against Seattle in the postseason.[109]

The 2022 season saw the Mariners return to the playoffs, in a year that included multiple bench-clearing incidents between the Astros and Mariners during the regular season. [110][111] The Mariners and Astros faced off in the 2022 ALDS, with Houston sweeping the Mariners in 3 games. The third and final game of that series was among the longest in postseason history; its 18 innings matched the longest game in playoff history and its 6 hours, 22 minutes was the third-longest in time [112],

The rivalry was a brief focus at the end of the 2025 season, after a 3 game sweep of the Astros in Houston by the Mariners in late September. [113] The sweep put the Mariners 3 games up in the division with 6 to play while all but eliminating the Astros from postseason contention. 3 days later, the Mariners won the AL West Division championship for the first time in 24 years.

American League

[edit]

Toronto Blue Jays

[edit]

Although the Toronto Blue Jays are not a divisional rival, many Blue Jays fans from Western Canada travel to Seattle when the Blue Jays are the visiting team. Seattle is about a three-hour drive from Vancouver. The Seattle Times estimated that Blue Jays fans represented around 70 percent of the crowd in Safeco Field for a June 2017 weekend series. [114] The Mariners broke their playoff drought in Toronto in the 2022 American League Wild Card Series with a dramatic comeback in Game Two, after being down by a deficit of one run to eight, winning by a final score of ten to nine. The two teams faced off again in the post-season in the 2025 American League Championship Series. Seattle took the first two games on the road in Toronto, but ultimately lost the series three games to four, with the Blue Jays winning game seven at home.

Interleague

[edit]

The Vedder Cup

[edit]

An unusual rivalry exists between the Mariners and the National League's San Diego Padres.[115] The matchup was designated one of the 15 "naturalized rivalries" when interleague play began in 1997, and the teams have played every year since, except 2017.[116][117]

Little on the surface links the two teams to any actual hostility, as both play in separate leagues and in cities that sit about 1,250 miles apart. Still, they share a spring training facility—the Peoria Sports Complex in Peoria, Arizona[118]—and in many years have competed for draft picks and prospects after failing to make the playoffs. (The Padres did not win a playoff series between 1999 and 2019, while the Mariners did not reach the playoffs from 2002 to 2021.[119][120]) Far from a bitter rivalry, it is viewed by the teams and most fans as more of a humorous contest.[121][122]

The rivalry had long been unofficially called the Vedder Cup after Pearl Jam frontman Eddie Vedder, who claims both Seattle and San Diego as hometowns but is a vocal fan of the Chicago Cubs.[123][124][125] In 2025, the rivalry was officially recognized as "The Vedder Cup", with the winner of the series being awarded a trophy designed by Vedder.[126][127][128][129][130] The Mariners won the Vedder Cup in 2025.

Seattle Mariners

View on Grokipedia
from Grokipedia
The Seattle Mariners are a professional baseball team based in Seattle, Washington, competing in Major League Baseball's (MLB) American League (AL) West division. Founded in 1977 as an expansion franchise, the team emerged from a lawsuit filed by Washington state officials against MLB after the short-lived Seattle Pilots relocated to Milwaukee following the 1969 season, marking the return of major league baseball to the Pacific Northwest. The Mariners initially played their home games at the from 1977 until mid-1999, enduring early struggles with losing records and attendance challenges before posting their first winning season in 1991. In 1999, they moved to the newly constructed Safeco Field (renamed in 2019), a retractable-roof stadium with natural grass that has hosted key events like the 2001 and enhanced the team's reputation as a modern venue. Despite never capturing a league pennant or title, the franchise has notable achievements, including their dramatic 1995 AL Division Series victory over the New York Yankees—featuring Martinez's iconic double—that helped secure public funding for the new ballpark and solidified the team's place in Seattle's sports culture. The 2001 season stands as the Mariners' pinnacle, tying MLB's single-season wins record with 116 victories en route to an AL West title, earning the Commissioner's Historic Achievement Award and showcasing stars like Ichiro Suzuki, who won AL MVP and Rookie of the Year honors that year. The team has made the playoffs six times (1995, 1997, 2000, 2001, 2022, and 2025), with the latter campaign seeing them claim the AL West crown before falling in the AL Championship Series. Iconic players such as Ken Griffey Jr. (1997 AL MVP, 10 Gold Gloves), Ichiro Suzuki (2001 AL MVP, 10 Gold Gloves), and Félix Hernández (2010 AL Cy Young) have earned multiple individual awards, contributing to the Mariners' legacy of developing Hall of Fame-caliber talent despite postseason frustrations. As of 2025, the Mariners maintain a .478 all-time winning percentage over 49 seasons, reflecting a franchise defined by resilience, regional pride, and ongoing pursuit of championship glory.

History

Founding and early years

The Seattle Mariners were established as an expansion franchise in Major League Baseball's American League following a lawsuit filed by Washington State Attorney General Slade Gorton against the league after the Seattle Pilots relocated to Milwaukee in 1970. On January 14, 1976, American League owners voted 11-1 to award Seattle an expansion team for the 1977 season, compensating the city for the Pilots' abrupt departure. The franchise's initial ownership group, led by actor Danny Kaye and businessman Lester Smith along with partners Stanley Golub, Walter Schoenfeld, James Stillwell, and James Walsh, paid an expansion fee of $5.53 million, with total startup costs reaching $6.5 million. The team name "Mariners" was selected on August 24, 1976, from a public contest won by Seattle resident Roger Szmodis, reflecting the city's maritime heritage. The Mariners played their inaugural game on April 6, 1977, at the against the California Angels, drawing a then-record 57,762 fans for an evening contest; U.S. Senator Henry "Scoop" Jackson threw the , and Diego Segui delivered the first official pitch in franchise history. The team lost 7-0, with Angels pitcher throwing a complete-game shutout, but secured their first victory two days later on April 8 in a 7-6 walk-off win, highlighted by Larry Milbourne's game-winning hit. Juan Bernhardt hit the franchise's first home run on April 10 against Tanana. Managed by Darrell Johnson, the 1977 Mariners finished with a 64-98 record, placing sixth in the AL West and drawing 1.3 million fans in their debut season. The early years were marked by consistent struggles, with the team posting losing records in each of its first 14 seasons, a major league record for the longest drought before a winning campaign. Ownership changed hands in 1981 when Greek shipping magnate purchased the franchise for $13.1 million, amid declining attendance that bottomed out at 813,537 in 1983. Multiple managerial shifts occurred, including in 1980 and in 1982, but the team lacked sustained success despite emerging talents like outfielder , selected first in the 1976 . By 1984, first baseman won Rookie of the Year honors, providing a brief highlight in an otherwise challenging era of rebuilding and financial instability. The Mariners were sold again in 1989 to an Indianapolis group led by for $76 million, setting the stage for further transitions into the 1990s.

Rise to contention and playoff breakthroughs

Following nearly a decade and a half of sub-.500 finishes since their 1977 inception, the Seattle Mariners began to emerge as contenders in the late 1980s through strategic drafts and trades that assembled a core of future stars. Outfielder was acquired from the New York Yankees in a 1988 trade, providing power hitting with 310 home runs over his Mariners tenure. The team selected first overall in the 1989 MLB Draft, who debuted that season and quickly became a franchise icon with his defensive prowess and offensive output. Also in 1989, the Mariners traded for left-handed pitcher from the , adding a dominant ace who would anchor the rotation for nearly a decade. These moves, under Woody Woodward, laid the foundation for contention amid ongoing attendance and ownership challenges. The 1991 season marked the Mariners' first winning record at 83-79, a milestone achieved under manager Jim Lefebvre and boosted by Griffey's .327 , 22 home runs, and first . Edgar Martinez, signed as an amateur in , emerged as a key offensive force, later winning the 1992 batting title with a .343 average. However, inconsistency plagued the early , with a 64-98 finish in prompting a change in ownership to of America, which stabilized the franchise. By 1993, the team posted an 82-80 mark, driven by Griffey's major league-leading 45 home runs and Johnson's league-high 308 strikeouts. Shortstop Alex Rodriguez joined in 1994 as the first overall draft pick, adding elite defense and speed to the lineup. The 1995 season represented the Mariners' breakthrough into playoff contention, shortened by a labor strike to 144 games but culminating in a 79-66 record that clinched the AL West on the season's final day via a win over the California Angels. Under manager , the team overcame a 13.5-game deficit in August, fueled by Johnson's AL Cy Young Award-winning 18-2 record and 2.48 , alongside Martinez's .356 batting title. In the AL Division Series against the New York Yankees, Seattle rallied from a 2-0 deficit, winning Game 5 6-5 in 11 innings on Martinez's iconic double that scored Buhner and Griffey from second and third, known as "The Double." The Mariners advanced to the AL Championship Series but fell 4-2 to the Cleveland Indians, marking their first postseason appearance after 19 seasons. This run not only saved the franchise from potential relocation but also galvanized , leading to voter approval for a new . Building on 1995's momentum, the Mariners returned to the in with a 90-72 record and another AL West title, setting a then-MLB record with 264 team home runs led by Griffey's MVP-season 56 homers. However, they were eliminated in the ALDS by the Baltimore Orioles 3-1. The 2000 campaign saw a 91-71 wild card berth, with the team sweeping the 3-0 in the ALDS behind strong pitching from and , before losing 4-2 to the Yankees in the ALCS. These appearances highlighted the rotation's depth, including Jamie Moyer's veteran presence after his 1999 acquisition. The pinnacle of this era came in 2001, when the Mariners tied the record with a 116-46 finish, the best in franchise history, clinching the AL West by 14 games. , signed from , won the batting title (.350), AL MVP, and Rookie of the Year honors, while Bret Boone set career highs with 37 home runs and 141 RBI. The team led MLB in runs scored (927), (.288), and fielding percentage, with Johnson contributing a 20-3 record before his midseason trade to . In the postseason, Seattle defeated the Indians 3-2 in the ALDS but were outmatched 4-1 by the Yankees in the ALCS, ending their deepest run to date. This breakthrough period from 1995 to 2001 established the Mariners as a model of sustained excellence, despite no appearance, with core players like Griffey, Rodriguez, and Johnson earning 10 selections combined during the decade.

Recent seasons and 2025 AL West championship

Following the 2001 season, the Mariners endured a prolonged period of rebuilding and inconsistency, failing to make the playoffs for 20 consecutive years from 2002 to 2021, the longest such drought in MLB history at the time. The team experienced roster turnover with the departures of many core players, but individual standouts like Ichiro Suzuki (who won the 2004 batting title and retired in 2019 with 2,533 career hits) and Félix Hernández (2010 AL Cy Young winner) provided highlights amid mostly sub-.500 seasons. Near-misses included 93 wins in 2002 and 90 wins in 2021. The drought ended in 2022 with a 90–72 record and a wild card berth, where Seattle defeated the Toronto Blue Jays in the AL Wild Card Series before losing to the Houston Astros in the AL Division Series. In the 2023 season, the Seattle Mariners finished with an 88-74 record, placing third in the and missing the following their 2022 appearance despite a strong pitching staff led by Luis Castillo and George Kirby. The team showed promise with young stars like contributing offensively, but inconsistencies in the lineup prevented a postseason berth. Attendance at remained robust, averaging over 33,000 fans per home game, reflecting sustained fan support amid the team's contention efforts. The 2024 campaign brought further challenges, as the Mariners ended with an 85-77 record, securing second place in the AL West but again falling short of the after a late-season surge. Scott Servais managed the first 128 games with a 64-64 mark before being replaced by Dan Wilson, under whom the team went 21-13 and won eight of their final 10 games. Key acquisitions like Victor Robles provided a boost, hitting .320 with 30 stolen bases in limited action, while the rotation continued to excel with emerging as a standout. Despite these highlights, offensive struggles and a competitive division kept on the outside looking in. Under Wilson's continued leadership in 2025, the Mariners broke through to claim their first AL West title since 2001, finishing 90-72 and clinching the division with a 9-2 victory over the Colorado Rockies on 24. The clinching moment came when reliever Luke Jackson struck out Blaine Crim for the final out, sparking on-field celebrations and marking the end of a 24-year division drought. Seattle's success was fueled by a dominant rally, winning 17 of 18 games to surge past rivals, with Rodríguez and anchoring the offense alongside a balanced pitching staff featuring Castillo and Gilbert. The team advanced to the AL Championship Series but fell 4-3 to the Toronto Blue Jays in a hard-fought series. Despite the postseason disappointment, the 2025 season represented a significant step forward, rebuilding momentum and validating Wilson's interim promotion as a permanent fixture.

Spring training venue

The Seattle Mariners conduct their spring training at the in , a facility they have shared with the Padres since its opening in 1994.

The franchise has evolved its visual identity multiple times, starting with a 1977 and in royal blue and gold to reflect 's seafaring roots, transitioning to a more stylized "M" in 1987, and adopting the current compass motif to align with the team's color scheme overhaul. The Mariners' official team colors, established in 1993, consist of (Pantone 289 C), northwest green (Pantone 342 C, a teal shade evoking waters), and metallic silver, with accents used sparingly for stitching in the . These hues replaced the original 1977 palette of , , and accents, which had been updated in 1979 with additional elements inspired by the region's and the team's inaugural All-Star Game hosting. The colors appear consistently across uniforms, caps, and merchandise, with northwest green serving as a distinctive highlight on navy bases, as seen in alternate designs like the 2015 Sunday home whites trimmed in silver and green. In 2023, the series introduced complementary shades—Amarillo yellow, Rush Blue, and Sundown orange—to nod to the 1977 inaugural uniforms while maintaining core identity ties. The team's mascot, Mariner Moose, is an anthropomorphic moose character dressed in a Mariners jersey, embodying fun and Northwest wilderness spirit despite moose not being native to the Seattle area. Introduced on April 13, 1990, during a sellout home opener at the Kingdome, the Moose was selected through a contest open to children 14 and under in the Pacific Northwest, receiving over 2,500 entries; fifth-grader Ammon Spiller's submission won for describing the moose as "funny, neat, and friendly." Over three decades, the Moose has entertained fans with acrobatic backflips, ATV parades around T-Mobile Park's warning track, and pranks like pieing opponents, becoming one of MLB's most recognized mascots. Notable incidents include a 1995 waterskiing stunt gone wrong during the ALDS, where performer Brett Rhinehardt suffered severe injuries after crashing into an outfield wall, and a 1996 Nike ad campaign portraying the Moose as a vice presidential candidate alongside Ken Griffey Jr. Today, the role is shared by multiple performers whose identities remain secret, with the Moose available for community appearances and symbolizing the team's approachable, adventurous ethos.

This design, emblematic of 1970s aesthetics, persisted with minor tweaks through 1992, including button-up styles introduced in the mid-1980s. The redesign marked a pivotal update, aligning the uniforms with contemporary MLB styles. Home jerseys adopted a "Mariners" trimmed in , accented by a crest above the "M," paired with matching caps featuring bills; road versions used "" in the same scheme on gray. This --silver palette symbolized the Pacific Northwest's maritime heritage and has remained the core identity, with a 2001 refresh introducing a bolder, italicized script for the wordmark. In , the primary set received subtle enhancements, including silver outlines on the Northwest Green trim for lettering and numbers to improve visibility and add a metallic sheen. Alternate and special uniforms have added variety, often nodding to franchise history. Since 2015, cream-colored Sunday home alternates have evoked the inaugural era, using lettering with gold trim, oversized block numbers on the back (without names), and a nautical patch on the sleeve—worn exclusively at . The 2023 Nike series introduced a bold jersey with "Seattle" in vintage Pilots-inspired lettering shadowed in black, Sundown gold accents, and black pants honoring the 1940s ; sleeve patches feature and "PNW" script, while the collar reads "Sodo Mojo" with trident motifs, celebrating regional innovation and roots. These were first worn in a series against the Astros and continue in rotation.

Development and notable alumni

The Seattle Mariners' player development system emphasizes a "Dominate the Zone" philosophy, which prioritizes pitchers throwing strikes in 0-0 and 1-1 counts to minimize walks and maximize swing-and-miss opportunities, a strategy introduced in 2016 under general manager Jerry Dipoto and vice president of player development Andy McKay. This approach has been integrated across the organization's minor league affiliates, including the Triple-A Tacoma Rainiers, Double-A Arkansas Travelers, High-A Everett AquaSox, Single-A Modesto Nuts, and rookie-level Arizona Complex League Mariners and Dominican Summer League Mariners, fostering a data-driven environment that refines mechanics and pitch arsenals through specialized camps like the annual "Dominate the Zone" pitching camp. The system also employs a "Draft, Develop, Trade" model, focusing on identifying high-upside talent via the MLB Draft and international signings, then enhancing their skills in a pitching lab that analyzes biomechanics and pitch shapes to optimize performance, particularly for relievers and starters. This development pipeline has produced several standout pitchers in recent years, exemplified by George Kirby (drafted 2019, first round), who posted a 3.43 ERA over his first three MLB seasons with elite command (1.2 BB/9), Logan Gilbert (2020, first round) with a 3.46 ERA and 9.3 K/9 through 2025, and (2021, sixth round), who has emerged as a key starter with a 2.77 ERA over 2024-2025. The Mariners' emphasis on zone control has elevated their farm system's reputation, ranking it among MLB's top groups in 2025 per Baseball America evaluations of talent depth and progression rates. Notable alumni from the Mariners' minor league system include Hall of Famer , selected first overall in 1987, who hit .320 with 27 home runs across three levels before debuting and later earning 13 selections and the 1997 AL MVP. , the 1993 first-round pick, progressed rapidly through the system at age 18, batting .358 in his stint and contributing 189 home runs during his Mariners tenure, including the 1996 AL batting title. , signed internationally in 2002, dominated minors with a 2.58 ERA before his MLB debut, culminating in the 2010 AL and a perfect game in 2012 after 15 seasons with the club. More recent successes highlight the system's evolution, such as , an international signee who ranked as MLB's No. 3 prospect in 2022 and won AL Rookie of the Year with a .284 average, 28 home runs, and 83 RBIs in his debut season. , the 2012 third overall pick, set power records with 62 home runs in college and affiliates, later becoming an elite defender with 95 MLB home runs before a 2018 trade. Adam Jones, developed through the system and named 2007 Player of the Year (.314 average, 25 home runs), transitioned to five appearances with post-2010 trade.
