Key Information

Early life

[edit]

Michael Bruce Fiers was born on June 15, 1985, in Hollywood, Florida. Fiers attended Deerfield Beach High School in Deerfield Beach, Florida, and graduated in 2003.[1]

College career

[edit]

Fiers enrolled at Broward College and played college baseball for the Broward Seahawks in 2004.[2] He transferred to the University of the Cumberlands for one year, in 2007, and had a 7–2 win–loss record and 3.68 earned run average (ERA) in 10 games for the Cumberland Patriots.[3]

In January 2008, Fiers fell asleep while driving on the Florida Turnpike, crashed into a guard rail, and was ejected through the windshield of the car. He broke four vertebrae.[3][4] After recovering, Fiers then transferred to Nova Southeastern University. Pitching for the Nova Southeastern Sharks in 2009, Fiers recorded a 10–3 record, a 2.65 ERA, and 145 strikeouts in 108+2⁄3 innings pitched, leading all of college baseball in strikeouts and breaking the Sharks' school record.[4][5]

Professional career

[edit]

Draft and minor leagues

[edit]

The Milwaukee Brewers selected Fiers in the 22nd round of the 2009 Major League Baseball draft.[6] He began his career playing for the Rookie league Helena Brewers, Class A Wisconsin Timber Rattlers, and Class A-Advanced Brevard County Manatees in 2009. Fiers played the 2010 season at Brevard and with the Double-A Huntsville Stars. He began the 2011 season with Huntsville, but was promoted to the Triple-A Nashville Sounds in late May 2011.[7]

Milwaukee Brewers (2011–2015)

[edit]

Fiers was called up to the majors for the first time on September 10, 2011.[6] He appeared in two games in the major leagues in 2011.

Fiers pitching for the Milwaukee Brewers in 2012.

On August 7, 2012, Fiers carried a perfect game into the 7th inning in a game against the Cincinnati Reds. He pitched eight innings allowing one run on three hits, earning the victory.[8] For the season, he started 22 games for the Brewers, going 9–10 with a 3.74 ERA in 127+2⁄3 innings. The following year, he was ineffective all season, only starting 3 times while making 8 relief appearances.

In 2014, Fiers split time between the majors and the AAA level. On September 11, pitching against the Miami Marlins, Fiers hit Giancarlo Stanton in the face with an 88-mile-per-hour (142 km/h) fastball, causing Stanton to be hospitalized.[9] With his next pitch, Fiers proceeded to hit Reed Johnson (pinch hitter who was completing Stanton's plate appearance) on one of his hands when he attempted to paint the inside corner. Both pitches were called strikes, because the batters were in the act of swinging. Miami third-baseman Casey McGehee, the on-deck batter, started yelling at the umpire, but Fiers thought that McGehee was yelling at him, so he tried to say that he did not do it on purpose; this then caused a bench-clearing shouting match. Fiers apologized to Stanton, and on September 12, Fiers was fined an undisclosed amount for causing the benches to clear.[10] He finished the season 6–5 despite posting an ERA of 2.13. In 14 games, 10 starts, he struck out 76 in 71+2⁄3.

On May 7, 2015, Fiers became the 73rd pitcher in MLB history to record an Immaculate inning when he struck out Enrique Hernandez, Carlos Frias, and Joc Pederson on 9 consecutive pitches in the fourth inning.[11] In 21 starts, Fiers was 5–9 with an ERA of 3.89. In 118 innings, he struck out 121.

Houston Astros (2015–2017)

[edit]

On July 30, 2015, the Brewers traded Fiers and Carlos Gómez to the Houston Astros for Brett Phillips, Domingo Santana, Josh Hader, and Adrian Houser.[12] On August 21, in his third start for the Astros, Fiers pitched a no-hitter against the Los Angeles Dodgers at Minute Maid Park, the 11th no-hitter in Astros history and the first for any team at Minute Maid Park. It was his first complete game as a major league pitcher. He finished the game with a career-high 134 pitches thrown, striking out 10 batters and walking three.[13] He finished 2–1 for Houston the rest of the 2015 season.

The following season, in 2016, he established a career high with 11 wins. He led the major leagues in wild pitches, with 17.[14]

On September 14, 2017, Fiers was suspended five games for throwing a pitch aimed at the head of Luis Valbuena.[15] Fiers made 29 appearances (28 starts), finishing the year with an 8–10 record and a 5.22 ERA. The Astros finished the 2017 season with a 101–61 record, clinching an AL West pennant. Fiers did not participate in the playoffs, but was still on the 40-man roster at the time. The Astros won the 2017 World Series, giving Fiers his first career championship ring.[16]

Detroit Tigers (2018)

[edit]

On December 8, 2017, Fiers signed a one-year, $6 million contract with the Detroit Tigers.[17] Fiers went through extended spring training due to a back injury, and was not on the Tigers 2018 opening day roster. He joined the team on April 8 and won his Tiger debut with six scoreless innings against the Chicago White Sox.[18] On April 21, Fiers became just the second Tigers player since 1908 to give up 10 or more hits in fewer than six innings, strike out nobody and earn a victory, and the first Tigers player to do since Dan Petry in 1984.[19]

Fiers compiled a 7–6 record and a 3.48 ERA in 21 starts for the 2018 Tigers before being traded.

Oakland Athletics (2018–2021)

[edit]

On August 6, 2018, Fiers was traded to the Oakland Athletics for two players to be named later or cash considerations.[20] Minor league pitcher Nolan Blackwood was later identified as one of the players. On August 14, Fiers earned his first win with the A's, surrendering two runs and striking out five over six innings against the Seattle Mariners.[21] On September 19, minor league pitcher Logan Shore was traded to the Tigers to complete the trade for Fiers.[22]

Fiers with the Athletics in February 2020

For the season, between the two teams he was 12–8 with a 3.56 ERA. He had the lowest line drive percentage allowed (17.3%) of all major league pitchers.[23]

On November 30, 2018, the Athletics non-tendered Fiers and he became a free agent.[24] He signed a two-year contract with the Athletics on December 24.[25]

On May 7, 2019, Fiers threw a no-hitter at Oakland-Alameda County Coliseum against the Cincinnati Reds, striking out six and walking two. It was the second no-hitter of his career, and the 300th in MLB history.[26] Facing the Astros on September 9, 2019, Fiers allowed career-highs of both nine runs on five home runs in one-plus innings, as the Astros established a record by hitting six home runs within the first two innings of the game.[27] Fiers finished 2019 with a record of 15–4 with an ERA of 3.90 in 33 starts. In 184+2⁄3 innings, he struck out 126. In 2020, he led the team in wins with 6. Curiously, despite pitching in the Wild Card Series, he was the only player on the roster to not pitch at any point of the ALDS against the Astros; the Astros dominated the Athletics in a four-game victory.

On February 6, 2021, Fiers re-signed with the Athletics on a one-year, $3.5 million contract.[28] Fiers began the 2021 season on the injured list (IL) and was activated towards the end of April, but after 2 starts he was placed back on the IL on May 9.[29] On May 21, Fiers was transferred to the 60-day injured list with a sprained right elbow.[30]

Leones de Yucatán

[edit]

On March 24, 2022, Fiers signed with the Leones de Yucatán of the Mexican League for the 2022 season.[31] At the time his contract was purchased, he had the league's second lowest ERA (2.84) and fourth lowest WHIP (1.20).

Uni-President Lions

[edit]

On June 29, 2022, Fiers had his contract purchased by the Uni-President Lions of the Chinese Professional Baseball League.[32] On August 10, Fiers was released and the contract was terminated after failing his physical.[33]

Role in Houston Astros sign stealing scandal

[edit]
Main article: Houston Astros sign stealing scandal

In November 2019, Fiers revealed to journalists Ken Rosenthal and Evan Drellich of The Athletic that in 2017 the Astros used a video camera in center field to steal signs from opposing teams. This was the catalyst for an MLB investigation into the Houston Astros sign stealing scandal.[34] Some baseball commentators, including analyst Jessica Mendoza and Hall of Famer Pedro Martinez, have criticized Fiers for coming forward publicly and only revealing the scandal once he was playing for a divisional rival, while many others in the baseball community defended him.[35][36][37]

Scouting report

[edit]

Fiers throws four pitches. He leads with a four-seam fastball at 88–91 miles per hour (142–146 km/h). He also has a slider (82–85 miles per hour (132–137 km/h)), curveball (70–74 miles per hour (113–119 km/h)), and changeup (79–83 miles per hour (127–134 km/h)). He also experiments with a cutter in the mid 80's for some extra movement to induce ground balls or surprise hitters. His primary off-speed pitch to lefties is the changeup and to righties is the curveball.[38] His changeup is considered by many to be his best pitch, and he has excellent command of the strikezone with all of his pitches. Despite having relatively low velocity, his command, the movement of his pitches (particularly his slow, looping curveball) all make him quite capable of racking up strikeouts. He had a K/9 of 9.6 during his four years in the minors, and has a respectable K/9 of 8.4 in the majors.

Michael Bruce Fiers (born June 15, 1985) is an American former pitcher who appeared in (MLB) primarily as a for the Brewers, Astros, Tigers, , and from 2011 to 2022. Drafted in the 22nd round of the 2009 MLB Draft by the Brewers after attending , Fiers debuted in the majors at age 26 in 2011 and established himself as a reliable mid-rotation starter known for his and control.

These feats highlighted his capacity for dominance despite inconsistent overall statistics, with career marks including a 4.49 ERA over 1,057.1 innings pitched. In November 2019, Fiers publicly revealed that the Astros had employed a center-field camera and trash-can banging system to illegally decode and relay opposing catchers' signs during their 2017 World Series-winning season, acting as the primary whistleblower after internal complaints yielded no resolution from MLB or team management. This disclosure prompted an MLB investigation confirming the cheating, resulting in punishments including fines, suspensions, and vacated records for the Astros, though Fiers faced backlash including death threats from some fans and players who viewed his actions as disloyal. His decision to speak out, after leaving the organization, underscored tensions in baseball's unwritten code of silence around competitive advantages, prioritizing game integrity over team allegiance.

Fiers struggled in 2013, limited to 22⅓ across 11 appearances (three starts) with a 1–4 record and 7.25 , allowing 31 hits and recording 15 strikeouts. Demoted to the and later Triple-A, his season reflected control issues and velocity dips, leading to a minor league stint for adjustment.

On August 14, he struck out a career-high 14 batters over six scoreless against the St. Louis Cardinals, securing a split in a doubleheader. His command-heavy approach, emphasizing off-speed pitches, yielded his best to date but ended prematurely due to a pectoral strain. Fiers opened 2015 in the Brewers' rotation, going 5–9 with a 3.89 in 21 starts and 118 , amassing 121 strikeouts and a 1.356 WHIP before the July 30 trade to the Houston Astros for outfielder Carlos Gomez.

Houston Astros tenure (2015–2017)

On July 30, 2015, the Houston Astros acquired Mike Fiers from the Milwaukee Brewers in a multi-player trade that also sent outfielder Carlos Gómez to Houston in exchange for prospects Brett Phillips, Domingo Santana, Adrian Houser, Josh Hader, and cash considerations. In 2015, Fiers made 10 appearances (9 starts) for the Astros after the trade, compiling a 2–1 record with a 3.32 over 62.1 and 59 strikeouts, while maintaining a 1.059 .

Detroit Tigers stint (2018)

Following his non-tender by the Houston Astros in November 2017, Fiers signed a one-year contract with the Detroit Tigers on December 7, 2017, worth $6 million. He experienced a lower back strain during in March 2018, which sidelined him and prevented him from making the roster; Fiers underwent extended before being placed on the 10-day disabled list on March 28, 2018.

No further professional appearances have been reported since the conclusion of that LIDOM campaign.

Houston Astros sign-stealing scandal

Details of the Astros' sign-stealing operation

The Houston Astros' sign-stealing operation in 2017 involved the use of a center-field camera feed, already installed for video replay purposes, to capture and decode opposing catchers' signs in real time. Players and staff accessed the live feed via a monitor placed near the dugout or in the video replay room, where they identified pitch types—typically distinguishing fastballs from off-speed pitches like curveballs—based on the catcher's finger signals, which teams often repeated predictably against the Astros. This decoding process was facilitated by player-developed tools, including an Excel-based algorithm known as "Codebreaker," which analyzed and cataloged opponents' signs from prior games or reports. To relay the decoded information to batters without direct verbal communication, Astros personnel banged a trash can positioned behind the dugout or near the batting circle, using auditory cues audible to the hitter amid crowd noise. The system employed a : one bang signaled an , while two bangs (or sometimes no bang) indicated a , with the signaling occurring shortly after the flashed the sign but before the delivered the pitch. Early in the 2017 season, alternative cues such as or whistling were tested but abandoned in favor of the trash can method for reliability; text messages to players' smartwatches or phones supplemented the process in some instances. The scheme was player-initiated and executed primarily by position players, with bench coach playing a central role in its coordination and setup, though manager was aware but did not participate or enforce cessation. The operation began at the start of the 2017 regular season and persisted through the playoffs, including the , contributing to the Astros' 101 regular-season wins and championship that year. In , a modified version continued without the dugout monitor—removed mid-season following MLB warnings—but relied on in-person communication from replay room staff to players, whom the team deemed less effective, leading to its abandonment later that year. MLB's investigation, conducted by former FBI director James Comey's firm and completed in January 2020, confirmed these methods violated league rules prohibiting electronic sign-stealing and real-time decoding outside traditional runner-based relays.

Fiers' decision to disclose and initial reports

In late 2019, Mike Fiers, who had pitched for the Astros from to 2017, decided to publicly disclose the team's use of electronic sign-stealing during home games in 2017, citing concerns over the integrity of the game and its impact on younger players' careers. Fiers explained that he had initially shared details privately with teammates on the Detroit Tigers in 2018 and the upon joining them, to prepare for matchups against the Astros at Minute Maid Park, but felt compelled to go public after observing persistent issues across . He stated, "I just want the game to be cleaned up a little bit because there are guys who are losing their jobs because they’re going in there not knowing," highlighting how the scheme disadvantaged opposing pitchers, particularly rookies who suffered poor outings and subsequent demotions. Fiers also noted a strained relationship with the Astros organization following his departure, which contributed to his willingness to speak out. Fiers chose to reveal the details to reporters Ken Rosenthal and Evan Drellich of The Athletic, rather than directly approaching officials beforehand, a decision later criticized by some figures like analyst Jessica Mendoza, who argued he should have reported it internally to MLB first. On November 12, 2019, The Athletic published the exposé, in which Fiers described the Astros' system: a center-field camera feed delayed by about 20 seconds and routed to a monitor near the dugout, with players banging on trash cans to signal pitch types to batters—once for fastballs, twice for off-speed pitches. The article corroborated Fiers' account with three anonymous sources from the 2017 Astros, noting the scheme's sophistication and its role in the team's World Series-winning season. The report triggered immediate fallout, with MLB announcing an investigation into the Astros that same day, led by the commissioner's office and conducted by former FBI director James Comey's firm. Media coverage proliferated rapidly, with outlets like and Yahoo Sports echoing the details of the camera-and-trash-can method, framing it as a violation of MLB rules prohibiting electronic sign-stealing during games. Fiers' disclosure marked the first public confirmation of systematic by the Astros, shifting focus from earlier rumors of sign-stealing in to concrete evidence of technological misuse, though some initial reactions questioned why Fiers waited two years after leaving the team.

Diverse reactions from players, fans, and media

Players exhibited a range of responses to Fiers' disclosure of the Astros' sign-stealing scheme, reflecting tensions between clubhouse loyalty and game integrity. Former Astros pitcher Mikolas or others implied betrayal by wishing Fiers had addressed issues internally while still with the team, stating, "I wish Fiers would have done it when he was on the Astros and not when he left," emphasizing that contemporaneous action would carry more credibility. Hall of Famer Pedro Martinez criticized Fiers for violating an unwritten code, arguing, "Whatever happens in the clubhouse stays in the clubhouse and Fiers broke the rules," while suggesting internal confrontation as the proper path for those valuing integrity. Conversely, New York Yankees general manager Brian Cashman credited Fiers with exposing hidden misconduct, noting, "If it wasn't for Mike Fiers, no one maybe ever would have known," positioning the disclosure as essential for deterrence. This divide underscored baseball's traditional "code of silence," where whistleblowing faced backlash from players prioritizing team confidentiality over external accountability. Fans' reactions polarized along team lines, with Astros supporters directing intense hostility toward Fiers for tarnishing their achievement. Astros fans frequently booed Fiers during games and issued death threats, prompting him to report the threats to authorities amid widespread online vitriol. In contrast, fans of affected teams like the , who lost the to Houston, celebrated Fiers as a whistleblower , cheering him loudly during a March 2020 spring training appearance at . This fan divide highlighted how tribal loyalties amplified defensiveness among Astros backers, who viewed the revelation as an attack on their franchise's legitimacy rather than a corrective measure. Media coverage captured the controversy's nuances, often framing Fiers as both and pariah depending on the outlet's emphasis on versus omertà-like norms. Publications like Yahoo Sports documented the "hero or snitch" debate, noting Fiers' role in prompting MLB scrutiny while acknowledging player resentment over his post-departure timing. David Ortiz's public labeling of Fiers as a "snitch" drew media analysis, with ESPN's defending the disclosure as vital for 's credibility despite cultural pushback. Outlets such as Athletics Nation praised Fiers for upholding rules against cheating, anticipating perpetual animosity from Astros stakeholders but prioritizing systemic integrity. Fiers largely withdrew from public commentary post-disclosure, citing fatigue with the scrutiny, which media interpreted as a retreat amid sustained debate.

MLB investigation outcomes and penalties

Major League Baseball's investigation into the Astros' sign-stealing activities, initiated following Mike Fiers' disclosures in November 2019, concluded on January 13, 2020, with Commissioner announcing the findings and penalties. The probe, conducted by MLB's Department of Investigations, confirmed that the Astros employed a camera-based system in to decode and relay opponents' catchers' signs via video feed to a center-field monitor, from which players signaled batters through bangs on a trash can; a less sophisticated banging scheme persisted into 2018 without electronic decoding. The Astros organization faced a $5 million fine, the maximum permissible under the league's constitution, and forfeiture of their first- and second-round draft picks in both the and 2021 MLB Drafts. Manager and general manager each received a one-year suspension without pay for the 2020 season; the Astros fired both executives the same day. Bench coach , implicated in the scheme, had already departed for the Boston Red Sox and received a similar suspension, later leading to his firing by that team. No individual players faced discipline, as MLB had granted them immunity from punishment in exchange for full cooperation during the investigation, a decision Manfred later described in 2023 as "not my best decision" due to the resulting lack of player accountability. This aspect drew widespread criticism for failing to vacate the Astros' title or impose on-field penalties, though Manfred defended the overall sanctions as sufficient to deter future violations while prioritizing organizational reform.

Playing style and performance analysis

Pitching repertoire and mechanics

Mike Fiers employed a five-pitch consisting of a , sinker, , , and . His typically ranged from 88 to 91 miles per hour, serving as a primary offering alongside a sinker used for inducing ground balls. The , thrown at 82-85 miles per hour, complemented his fastball mix, while the operated in the 79-83 miles per hour range to disrupt timing against opposite-handed batters. Fiers' , clocked at 70-74 miles per hour, featured significant vertical drop, contributing to high ground-ball rates on the pitch. Usage percentages across his career highlighted reliance on sinking pitches, with the sinker comprising about 33% of offerings, followed by the slider at 25% and at 23%. and were secondary, at roughly 11% and 8% respectively, often deployed situationally for deception. Fiers occasionally incorporated a cutter in the mid-80s range earlier in his career to add horizontal movement. Fiers' mechanics featured an over-the-top arm slot that enhanced by hiding the ball deep in his delivery, compensating for below-average . He demonstrated consistent in his motion, though critics noted potential losses from hip collapse and arm path inconsistencies, which limited gains. Adjustments, such as lowering his arm slot in 2017, altered pitch trajectories, notably increasing effectiveness by enhancing its drop. This positional tweak on the rubber and refined pitch sequencing underscored his adaptability, prioritizing movement and location over raw speed.

Key statistical achievements and no-hitters

Fiers pitched the first of his two major league no-hitters on May 7, 2015, for the Houston Astros against the at Minute Maid Park, resulting in a 4-0 victory. During the game, he recorded an immaculate inning in the fourth, striking out three batters on nine pitches. This performance marked a career highlight early in his Astros tenure, following a 2014 season where he established himself as a rotation option with a 2.55 over 22 starts for the Milwaukee Brewers. His second no-hitter came on May 7, 2019, for the against the at , securing a 2-0 win on 131 pitches with two walks and six strikeouts. This effort represented the 300th in MLB history and made Fiers the 35th pitcher to achieve multiple no-hitters, joining an elite group including and . Notably, entering the 2019 game, Fiers held the highest career (4.88 at the time) among pitchers throwing a no-hitter. Across his MLB career spanning 2011 to 2021, Fiers compiled a 75-64 record with a 4.07 and 995 strikeouts in 1,221⅓ innings over 239 appearances (198 starts). His 2019 season stood out statistically, with career highs in (180⅓), strikeouts (180), and a personal-best 3.69 , contributing to 15 wins for the Athletics. Uniquely, in his 160 starts excluding the no-hitters, Fiers never recorded an out in the ninth inning or later, underscoring the rarity of his complete-game shutouts.

Strengths, weaknesses, and career trajectory

Fiers' professional career commenced after being selected by the Milwaukee Brewers in the 22nd round of the 2009 MLB Draft out of , where he had posted a 3.11 and 145 strikeouts in 108.2 during his senior year. He debuted in the majors on September 14, 2011, initially serving as a reliever before transitioning to starting roles, with a breakout 2014 season featuring a 2.55 over 114.1 in 17 starts. Traded to the Tigers on , 2015, following a against the on August 21, Fiers continued as a starter but experienced inconsistency, including a to the early in subsequent seasons. Signed by the Houston Astros prior to the 2017 season, Fiers posted a 4.10 across two years before a mid-2018 trade to the , where he thrived in a rotation spot, achieving a career-best 3.90 in 2019 en route to his second against the on May 7. His Athletics tenure through 2021 yielded 11.0 overall, reflecting steady mid-rotation production despite declining peripherals. Fiers' trajectory exemplifies a late-blooming : undrafted out of high school, overlooked in early pro ball, yet peaking in his early 30s through adaptability before fading from MLB rotations amid rising hard contact rates. Key strengths as a included exceptional command, evidenced by a career 7.0% walk rate, and a repeatable delivery that concealed the ball effectively, enhancing deception against hitters. His arsenal—primarily sinker (32.9% usage), (25.0%), and four-seamer (23.0%)—leveraged movement over velocity, with adjustments like a deeper under coaching boosting vertical drop by over five inches and elevating whiff rates. Weaknesses centered on below-average fastball velocity (typically 90-92 mph), classifying him as a soft-tosser vulnerable to elevated contact, as seen in a career 38.8% groundball rate and higher-than-ERA FIP of 4.52 indicating defensive dependence. Mechanical flaws, such as backside collapse reducing drive and an overhand slot limiting extension, contributed to hittable s often left up in the zone. Later-career metrics, including 50% hard-hit rate in 2021, underscored diminishing ability to suppress barrels against power-hitting lineups.

Legacy and impact

Contributions to baseball integrity

Mike Fiers' public disclosure of the Houston Astros' electronic sign-stealing scheme on November 12, 2019, in an interview with , marked a pivotal moment in addressing cheating in . As a former Astros from 2015 to 2017, Fiers detailed how the team used a center-field camera feed piped to a monitor near the dugout, from which players banged trash cans to signal pitch types to batters during home games in 2017. This revelation, corroborated by multiple former teammates, violated MLB rules prohibiting electronic devices for decoding signs, prompting to launch a formal investigation under former commissioner . The investigation, initiated directly in response to Fiers' allegations, confirmed the scheme's operation throughout the 2017 regular season and playoffs, including the Astros' victory. MLB imposed severe penalties on January 13, 2020: a $5 million fine—the maximum allowed—a forfeiture of first- and second-round draft picks in 2020 and 2021, and one-year suspensions for manager and general manager , who were subsequently fired by the team. These measures held the organization accountable, stripping it of ill-gotten competitive edges and leadership complicit in the violations, thereby restoring a measure of competitive tainted by the . Fiers' whistleblowing extended baseball's emphasis on ethical conduct by exposing vulnerabilities in technology oversight and player incentives, influencing MLB's subsequent enforcement practices. Post-scandal, the league enhanced video room monitoring, restricted replay system access during games, and issued stricter guidelines on electronic equipment to deter similar schemes league-wide. His action underscored the role of individual accountability in upholding rules against sign-stealing, as electronic methods had proliferated despite longstanding prohibitions, fostering a culture where fair play supersedes short-term gains.

Criticisms of whistleblowing approach

Some players and observers criticized Fiers for not addressing the sign-stealing internally during his time with the Astros in , arguing it reflected poor teammate . Hall of Famer Pedro Martinez stated that Fiers was a "bad teammate" for remaining silent while benefiting from the scheme, suggesting he should have confronted the issue within the clubhouse rather than waiting until after departing the in December . Similarly, David Ortiz questioned why no Astros players, including Fiers, spoke out contemporaneously, portraying Fiers as resembling a "snitch" who only disclosed after leaving and securing contracts elsewhere, such as with the Detroit Tigers in 2018 and in 2019. Critics also faulted Fiers' decision to reveal the publicly through a November 12, 2019, article in rather than formally reporting to (MLB) officials beforehand, viewing it as bypassing proper channels and prioritizing media exposure. This approach, some argued, complicated MLB's investigation and fueled perceptions of self-interest, especially since Fiers had privately warned his Tigers and teammates about Astros tactics upon joining those clubs but delayed broader disclosure until two years post-championship. Baseball's entrenched "" amplified such views, with former players expressing mixed sentiments that violated unwritten norms of collegiality over institutional accountability. These critiques persisted amid broader backlash, including from Astros-affiliated figures like , who questioned the timing and public nature of Fiers' revelations, though her ties to MLB broadcasting raised concerns of conflicted incentives. Despite defenses that internal efforts were futile amid clubhouse , the approach drew ire for potentially undermining player trust across teams and prolonging the scandal's resolution.

Long-term career evaluation

Mike Fiers compiled an 11-year Major League Baseball career from 2011 to 2021, primarily as a starting pitcher for the Milwaukee Brewers, Houston Astros, Detroit Tigers, and Oakland Athletics, amassing 75 wins, 64 losses, a 4.07 ERA, 1,351.1 innings pitched, 995 strikeouts, and a 1.278 WHIP. His career Wins Above Replacement (WAR) totaled 13.4, indicative of a solid mid-rotation contributor but short of elite status, as his adjusted ERA+ of 101 matched league average over the period. Fiers' trajectory featured late development after being selected in the 22nd round of the 2009 draft; he debuted unremarkably with the Brewers before a 2014 breakout that included a no-hitter against the Atlanta Braves on August 21, highlighting his curveball-heavy arsenal's capacity for deception. Traded mid-2015 to the Astros, he contributed to their 2017 World Series roster with a 3.32 ERA in limited action, though his overall tenure reflected journeyman reliability rather than dominance. Fiers peaked offensively in 2019 with the , posting 15 wins, a 3.90 , and a second against the on May 7—the 300th in MLB history—amidst his public disclosure of the Astros' sign-stealing scheme. This disclosure in November 2019 did not immediately derail his employment, as the retained him for 2020 (6-3, 4.58 in a shortened season) before his sharp 2021 decline to a 7.71 in 9.1 at age 36, aligning with typical age-related velocity loss and increased hard contact allowed. Absent MLB offers post-2021, Fiers pitched in in 2022 and later assumed duties, marking effective retirement from professional playing. Long-term, Fiers' career underscores resilience for an undrafted late-round pick, with no-hitters as pinnacles amid consistent but unexceptional peripherals; his 4.07 masked occasional brilliance but exposed vulnerabilities to home runs and walks, culminating in a respectable yet replaceable profile in an era favoring power arms. While the elevated his off-field profile, on-field metrics suggest his longevity stemmed from adaptability rather than superior talent, yielding positive value across franchises without anchoring rotations.
