Paul Mainieri (born August 29, 1957) is a former American college baseball coach. He played college baseball at LSU, Miami-Dade CC and New Orleans before pursuing a professional baseball career. He then served as the head coach of the St. Thomas Bobcats (1983–1988), Air Force Falcons (1989–1994), Notre Dame Fighting Irish (1995–2006), LSU Tigers (2007–2021), and South Carolina Gamecocks (2024-2026). Mainieri coached LSU to the 2009 College World Series Championship.

Key Information

Playing career

[edit]

Mainieri graduated from Christopher Columbus High School in Miami. He started his college baseball playing career in 1976 at LSU. He played for one season, earning a letter, before transferring to Miami-Dade North Community College to play for his father, Demie Mainieri. After one year he transferred to the University of New Orleans where he played for two years and helped the team win two Sun Belt Conference titles and earn an appearance in the 1979 NCAA Division I baseball tournament. In 1978, he played collegiate summer baseball with the Wareham Gatemen of the Cape Cod Baseball League, and was named a league all-star.[1]

Mainieri completed his undergraduate degree requirement at Florida International University in 1980, earning a B.S. in physical education. He played two years of minor league baseball and earned a M.S. in sports administration from St. Thomas University in 1982.

Coaching career

[edit]

St. Thomas

[edit]

Mainieri began his coaching career in Florida as the head coach of St. Thomas University in 1983. In six seasons, his team went 179–121–2, and Mainieri became the winningest coach in St. Thomas History. His No. 1 jersey was retired by the university in February 2012. In 2013, the new field at St. Thomas University was named in his honor. The Bobcats' new field is called Paul Demie Mainieri Field at Frank R. Esposito Stadium. Paul Mainieri asked the university to include his middle name, Demie, in the naming of the field because it is the same name as his father's first name. Both Mainieris have deep roots with St. Thomas, and recently became the first father-son duo to be elected to the American Baseball Coaches Association Hall of Fame.

Mainieri was inducted into the St. Thomas Hall of Fame on November 1, 2009. Mainieri became the sixth person to be inducted into the St. Thomas Hall of Fame, joining Ken Stibler, Marinka Bisceglia, Manny Mantrana, Laura Courtley-Todd and John Batule.[2]

Air Force

[edit]

He moved on to the United States Air Force Academy in 1989, where he would also remain for six seasons. He became the second-winningest coach in Air Force history posting a mark of 152–158.

Notre Dame

[edit]

Moving to the Notre Dame Fighting Irish in 1995, Mainieri turned the Fighting Irish into a perennial postseason contender winning the Big East tournament a record 5 straight seasons, making the NCAA tournament 9 out of 12 seasons, and leading the Irish to one College World Series appearance in 2002. He won the 2001 Big East Coach of the Year award. In total, Mainieri posted a .714 winning percentage going 533–213–3 in twelve seasons.

LSU

[edit]

Mainieri replaced Smoke Laval at the end of the LSU Tigers' 2006 season. In the 2007 season, LSU finished 29–26–1 and did not reach the NCAA tournament.

40 games into the 2008 season, the Tigers were again struggling with a 23–16–1 record. However, the team then went on a Southeastern Conference record 23-game win streak and moved on to claim the 2008 SEC Tournament championship. Under Mainieri's leadership, the team swept the Baton Rouge Regional bracket of the NCAA baseball post-season and won their first Super-Regional since 2004. UC Irvine ended the streak in the first game of the Super Regional, defeating LSU 11–5, but LSU won the next two games and reached the 2008 College World Series. It was LSU's first College World Series appearance since 2004 and they recorded their first win since their CWS championship in 2000.

Mainieri's Tigers entered the 2009 season as the favorites to win the SEC, and were the preseason No. 1 team in some national polls.[3] During the season, the Tigers won the SEC regular season title, the 2009 SEC Tournament championship, and reached the 2009 College World Series as the No. 3 national seed. Mainieri then led LSU to the CWS Finals against Texas. The Tigers won the first game 7–6 in 11 innings, lost the second 5–1, but won the national championship defeating the Longhorns 11–4 in the final game. The Tigers finished the season with a 56–17 record. Mainieri received the 2009 Coach of the Year award from Collegiate Baseball Newspaper and the 2009 Coach of the Year award by Baseball America. Rivals.com also named Mainieri the 2009 National Coach of the Year.[4][5][6]

The 2009 title was the sixth in LSU baseball history, tying Texas for the second most national championships in college baseball history, and Mainieri joined Skip Bertman as the only LSU baseball coaches to win a national championship.

In 2015, Mainieri received the National Coach of the Year award from the National Collegiate Baseball Writers Association and the Skip Bertman Award presented by the College Baseball Foundation.[7] During the 2017 season, LSU played Florida in a best-of-three series to determine the winner of the 2017 College World Series. Florida swept LSU and the Tigers finished as College World Series runner-up.[8] Mainieri announced his retirement from coaching after the conclusion of the 2021 season.[citation needed]

South Carolina

[edit]

Paul Mainieri was named the 31st head coach of the South Carolina Gamecocks baseball program on June 11, 2024.[9] In the 2025 season, the Gamecocks compiled a 28–29 (6–24 SEC) record and missed the NCAA tournament. After a 12–11 start to the 2026 season, Mainieri and South Carolina agreed to part ways on March 21, 2026.[10]

View on Grokipedia
from Grokipedia
Paul Mainieri (born August 29, 1957) is an American college baseball coach who served as the head coach of the University of South Carolina Gamecocks in the Southeastern Conference (SEC). With over four decades of experience, he is a leader in NCAA Division I wins, amassing a career record of 1,545–817–8 (.654) across 40 seasons at five institutions. A member of the American Baseball Coaches Association (ABCA) Hall of Fame since 2014, Mainieri is renowned for leading LSU to the 2009 NCAA national championship and guiding multiple programs to deep postseason runs, including six College World Series appearances. Mainieri's coaching career began after earning a B.S. in physical education from Florida International University in 1980 and an M.S. in sports administration from St. Thomas University in 1982.[1] He started as head coach at St. Thomas University from 1983 to 1988, where his teams averaged 30 wins per season, followed by a stint at the United States Air Force Academy from 1989 to 1994, averaging 26 wins annually despite the service academy's challenges.[2] At the University of Notre Dame from 1995 to 2006, he compiled a 533–213–3 (.714) record, won nine Big East Conference titles, and led the Fighting Irish to their first College World Series in 2002.[2] His most successful period came at Louisiana State University (LSU) from 2007 to 2021, where he posted a 641–285–3 (.692) mark and secured 31 team championships, including the 2009 NCAA title, five College World Series trips (2008, 2009, 2013, 2015, 2017), four SEC regular-season titles, and six SEC Tournament crowns. After retiring from LSU in 2021, he returned to coaching in June 2024 as South Carolina's 31st head coach; his tenure included a 28–29 record in 2025 and ended in March 2026 after a 12–11 start to the 2026 season.

Early life and education

Family and upbringing

Paul Mainieri was born on August 29, 1957, in Morgantown, West Virginia.[3] His father, Demie Mainieri, was born on October 21, 1928, in Jersey City, New Jersey, as the youngest of 11 children in a large Italian immigrant family.[4] Demie earned a Ph.D. in administration from Columbia University before marrying Rosetta McBee, a dairy farmer's daughter from West Virginia, on December 26, 1953; the couple had five children, including Paul.[4][5] Following Demie's completion of his doctorate, the family relocated from West Virginia to Miami, Florida, where he began his distinguished coaching career at Miami-Dade North Community College, amassing 1,012 wins and a national championship over 30 years.[6][7] Growing up in a family of seven in Miami, Paul was immersed in baseball from an early age, often spending time in the dugout during his father's practices and games, which sparked his lifelong passion for the sport.[8][9] This early exposure under Demie's mentorship profoundly shaped Paul's future trajectory in baseball coaching.[6]

College years

After graduating from Christopher Columbus High School in Miami, Florida, Mainieri earned his Bachelor of Science degree in physical education from Florida International University in 1980.[3][2] This academic path reflected his early interest in sports-related fields, influenced by his family's deep baseball legacy.[10]

Playing career

High school baseball

Paul Mainieri attended Christopher Columbus High School in Miami, Florida, where he participated in both baseball and football during his high school years.[11] As a multi-sport athlete, he played as a shortstop on the baseball team and as a quarterback on the football team.[11] In baseball, Mainieri earned recognition as an All-County shortstop during his senior year, contributing to his team's appearance in the Florida state championship game in both his sophomore and senior seasons, though the Explorers fell short in both contests.[11][12] His standout performance across sports led to him being named Christopher Columbus High School's Athlete of the Year in 1975.[11] In recognition of his high school contributions, Mainieri was inducted into the Christopher Columbus High School Sports Hall of Fame in October 2009.[3] Following his graduation from high school in 1975, Mainieri was recruited to continue his baseball career at Louisiana State University, where he began playing in 1976.[13]

Collegiate baseball

Mainieri began his collegiate baseball career at Louisiana State University in 1976, where he played as an outfielder and earned a varsity letter.[3] In 43 games, he recorded 91 at-bats, 7 runs, 16 hits, 1 double, and a batting average of .176.[14] The Tigers finished the season with a 19–23 overall record and 11–12 in Southeastern Conference play, placing third in the West Division.[15] Following his freshman year, Mainieri transferred to Miami-Dade North Community College in 1977 to play under his father, Demie Mainieri, the program's legendary head coach. This move allowed him to compete in a competitive junior college environment shaped by his father's emphasis on discipline and fundamentals, though specific individual statistics from the season remain undocumented in available records. The Falcons, known for their strong tradition under Demie Mainieri, provided a platform for Paul to develop his skills amid a roster that included future professionals. Mainieri completed his collegiate career with two seasons at the University of New Orleans from 1978 to 1979, transitioning to second base.[3] In 1978, the Privateers posted a 35–16 record and won the Sun Belt Conference championship.[16] That summer, Mainieri played for the Wareham Gatemen in the Cape Cod Baseball League, where he was named an all-star.[17] The following year, UNO improved to 49–14, repeated as conference champions, and qualified for the NCAA Tournament.[16] Comprehensive career batting statistics across his four collegiate seasons, including total home runs and RBIs, are not publicly detailed, but his contributions as a steady infielder helped anchor UNO's successful runs. After college, Mainieri was selected by the Chicago White Sox in the 28th round of the 1979 MLB Draft and played one professional season with the Niagara Falls Pirates in the New York-Penn League, batting .253 with a .397 on-base percentage and 12 stolen bases in 60 games.[18] With limited advancement opportunities in professional baseball, he shifted focus to coaching, beginning as an assistant at St. Thomas University in 1980.[3]

Coaching career

Early coaching roles

After completing his collegiate playing career, Paul Mainieri returned to his alma mater, Christopher Columbus High School in Miami, Florida, to begin his coaching journey as an assistant for the baseball and football teams from 1980 to 1982.[18][3] In these roles, he supported the head coaches by assisting with practice sessions, game preparation, and athlete instruction across both sports, building on the foundational knowledge from his own standout high school and college baseball experiences.[3][1] Mainieri's time at Columbus High School marked his initial foray into structured coaching, where he honed skills in motivating young athletes and implementing team strategies, though specific team outcomes from his assistant contributions are not extensively documented.[18] His efforts during this period were later honored when he was inducted into the Columbus High School Sports Hall of Fame in October 2009, recognizing his lasting impact as both a player and early coach.[3] This formative assistant experience provided Mainieri with practical insights into leadership and program building, facilitating his transition to higher education coaching and culminating in his first head coaching opportunity at St. Thomas University starting in 1983.[18][10]

St. Thomas University (1983–1988)

In 1983, at the age of 25, Paul Mainieri was hired as the head baseball coach at St. Thomas University in Miami, Florida, becoming the youngest head coach in the program's history and taking over a team that had never posted a winning season in its prior six years of existence.[1] His tenure from 1983 to 1988 marked the first sustained success for the Bobcats, compiling an overall record of 179–121–2 and a .597 winning percentage.[18] This performance elevated the program from an average of just 18 wins per season before his arrival to an average of 30 wins annually under his leadership.[19] Mainieri's teams achieved several milestones, including four national top-10 rankings in NCAA Division II polls during his six seasons.[20] The 1984 season stood out as his most successful, with a 37–14 record that set a school record for victories and earned him Sunshine State Conference Coach of the Year honors, despite Florida Southern claiming the conference title.[18][1] In 1987, his squad led the nation with a .340 team batting average, showcasing offensive prowess in a 35–21 campaign.[19] While the Bobcats did not qualify for the NCAA Division II national tournament during this period, Mainieri's emphasis on disciplined fundamentals and competitive scheduling within the Sunshine State Conference laid a foundation for consistent contention.[21] Mainieri's program-building efforts extended beyond the field, as he also served as the university's director of athletics from 1986 to 1988 while fostering a culture of professionalism that produced 15 players who signed professional contracts, including three who reached Major League Baseball: pitcher Joe Klink (Chicago White Sox, 1987–1989), pitcher Dane Johnson (Montreal Expos, 1991), and infielder Dan Rohrmeier (Milwaukee Brewers, 1995).[22] These developments transformed St. Thomas baseball into a respected program known for player development. Mainieri departed after the 1988 season, accepting the head coaching position at the U.S. Air Force Academy.[18]

U.S. Air Force Academy (1989–1994)

Paul Mainieri served as the first civilian head baseball coach at the United States Air Force Academy from 1989 to 1994, transitioning from his successful NAIA tenure at St. Thomas University to Division I competition within the Western Athletic Conference (WAC).[2] Over six seasons, he compiled an overall record of 152–158 (.490 winning percentage), averaging 26 wins per year—a marked improvement from the program's prior average of 15 wins annually in the preceding six seasons.[23] His teams achieved six consecutive 20-win seasons, a program first, though they struggled in WAC play, posting a 38–105 conference record. Mainieri's best conference finish came in 1989, when the Falcons went 13–13 in the WAC to tie for fourth place, setting a school record for league wins that season.[1] Subsequent years saw declining WAC results, including a 1–20 mark in 1991 (ninth place) and finishes no higher than eighth thereafter, despite solid overall records like 28–22 in 1993. The 1994 squad provided a highlight with a 26–24 overall record and national rankings in offense, leading the country in batting average (.360), triples per game (0.76), and slugging percentage (.623), while ranking third in runs per game (9.34).[23] However, persistent issues with pitching (team ERA of 10.22 in 1994) and defense (fielding percentage of .941 that year) hampered deeper success. Coaching in a service academy environment presented unique challenges for Mainieri, including the intense military commitments of cadet-athletes that limited practice time and player development compared to traditional programs.[24] Recruiting was restricted to prospects meeting rigorous academy admissions standards, yet Mainieri developed notable talent, including three All-Americans, two Freshman All-Americans, and 12 all-conference selections, such as outfielder Lance Pilch, a four-year starter and Academic All-American who later became a colonel and pilot.[25] Despite a strong 12–4 record against other service academies during his tenure, the Falcons made no postseason appearances. Mainieri resigned after the 1994 season to accept the head coaching position at the University of Notre Dame.[23]

University of Notre Dame (1995–2006)

Paul Mainieri was appointed head baseball coach at the University of Notre Dame in 1995, bringing experience from his successful turnaround at the U.S. Air Force Academy that prepared him for leading a Division I program in the competitive Big East Conference.[2] Over his 12-year tenure, Mainieri transformed the Fighting Irish into a consistent contender, compiling an overall record of 533–213–3 for a .714 winning percentage.[18] His teams achieved 11 seasons with 40 or more wins, captured multiple Big East Conference regular-season and tournament titles—including five consecutive Big East Tournament championships from 2002 to 2006—and made nine appearances in the NCAA Tournament, all reaching regionals.[2][26] A highlight of Mainieri's era at Notre Dame came in 2002, when the Fighting Irish advanced to the College World Series for the program's first appearance since 1957, finishing with a 50–18 record and defeating Rice in the super regional.[18] Mainieri's coaching emphasized player development, producing eight players who reached Major League Baseball, including standout pitcher Brad Lidge, who became an All-Star closer and World Series MVP with the Houston Astros and Philadelphia Phillies; Aaron Heilman, a key reliever for the New York Mets; and Jeff Samardzija, who enjoyed a long MLB career as a starter and reliever for multiple teams.[3] These successes elevated Notre Dame's national profile, with the program earning its first No. 1 ranking in 2001 under Mainieri's leadership.[26] In June 2006, following a 45–17–1 season that included another Big East title and NCAA regional berth, Mainieri departed Notre Dame to accept the head coaching position at Louisiana State University, his alma mater, where he sought to return to his roots in the Southeastern Conference.[27]

Louisiana State University (2007–2021)

Paul Mainieri served as head baseball coach at Louisiana State University (LSU) from 2007 to 2021, compiling an overall record of 641–285–3, which equates to a .692 winning percentage.[3] During his 15-year tenure, he led the Tigers to five College World Series appearances in 2008, 2009, 2013, 2015, and 2017, establishing LSU as a consistent national contender in NCAA Division I baseball.[3] Mainieri's teams also secured four Southeastern Conference (SEC) regular-season titles in 2009, 2012, 2015, and 2017, along with six SEC Tournament championships.[3] He earned SEC Coach of the Year honors twice, in 2009 and 2015, and received multiple national accolades, including the American Baseball Coaches Association (ABCA) National Coach of the Year in 2009 and the Skip Bertman Award in 2015.[3][28] The pinnacle of Mainieri's LSU career came in 2009, when the Tigers won the NCAA national championship with a 56–17 overall record and a perfect 10–1 mark in the NCAA Tournament.[3] Key roster standouts included outfielder Jared Mitchell, who was named the College World Series Most Outstanding Player after hitting a crucial three-run home run in Game 3 of the finals against Texas, powering LSU to an 11–4 victory and clinching the title. Other notable contributors were second baseman Matty Zander, who provided steady defense and timely hitting, and pitcher Louis Coleman, who delivered strong outings in postseason play.[3] The championship run featured dramatic wins, such as a 7–6 victory over Texas in Game 1 of the finals, highlighted by Mitchell's offensive spark, before Texas forced a decisive third game with a 7–6 comeback in Game 2.[29] This triumph marked LSU's sixth national title and solidified Mainieri's reputation for strategic postseason management. Mainieri's later years at LSU demonstrated sustained excellence amid challenges, including the COVID-19 pandemic, which shortened the 2020 season to just 17 games (12–5 record) before cancellation and granted extra eligibility that affected roster dynamics in 2021.[30] The 2021 Tigers finished 38–25, reaching the NCAA Super Regional before elimination.[31] On May 28, 2021, Mainieri announced his retirement effective at the end of the season, citing a desire to step away after leading LSU to 11 seasons of at least 40 wins in his 14 full campaigns.[32] His legacy includes developing 25 Major League Baseball players and 90 MLB Draft selections, with infielder Alex Bregman emerging as a prime example; Bregman, who played for LSU from 2013 to 2015, won the Brooks Wallace Award as the nation's top shortstop in 2013 and helped secure the 2015 SEC title before becoming the No. 2 overall pick in the 2015 MLB Draft.[3][33] Mainieri's emphasis on player development and academic success—evidenced by 103 degrees earned by his players—left an enduring impact on the program.[3]

University of South Carolina (2024–2026)

Mainieri was hired as head coach in June 2024 after retiring from LSU. In his first season (2025), he led the Gamecocks to a 28-29 record (6-24 SEC). Retained for 2026, but after a 12-11 start (0-4 SEC), the university and Mainieri mutually agreed to part ways on March 21, 2026. His overall record at South Carolina was 40-40 over 80 games across parts of two seasons. Monte Lee was named interim head coach.

In 2000, while at Notre Dame, he earned the honor from College Baseball Insider after guiding the Irish to a 51–15 record and their first College World Series appearance.[3] In 2008, during his second season at LSU, Mainieri was named National Coach of the Year by Rivals.com after guiding the Tigers to a 49–19–1 record.[42] At LSU in 2009, following the national championship, Mainieri was named National Coach of the Year by both the American Baseball Coaches Association (ABCA) and Baseball America.[43][44] In 2015, he received the award from the National Collegiate Baseball Writers Association (NCBWA) after leading LSU to a 55–14 record, the SEC regular-season title, and a No. 1 national ranking.[45] Additionally, Mainieri won the prestigious Skip Bertman Award as the National Coach of the Year in 2015, presented by the College Baseball Hall of Fame for his role in LSU's dominant season that included 29 team championships and the development of multiple All-Americans.[28] Within the Southeastern Conference, he was named SEC Coach of the Year in 2009 after LSU's 18–11 league mark and national title run, and again in 2015 for securing the program's 16th regular-season championship with a 22–8 conference record.[45]
