Lamar University Athletics

Regarded as one of the top assistant coaches in the country, Sean Allen was named Lamar University head coach June 2^nd, 2026. Allen makes his way to the Golden Triangle after serving the previous two years as the pitching coach at Southern Cal. Allen brings more than two decades of experience with him that includes stops in the Southland Conference, the state of Texas and some of the premier programs in the sport.
 
Over the course of his career, Allen has put together a résumé that few, if any, can compete with. Those numbers include 82 MLB draft selections, 18 All-Americans (six Freshman All-Americans), 16 NCAA Regional appearances, 13 big league players, seven former conference players and/or pitchers of the year, nine conference championship titles, six NCAA Super Regionals (including 2026 at USC – the program’s first super regional appearance since 2005), three College World Series appearances, three Golden Spikes Award finalists, two Dick Howser Award winners (Ivan Melendez and Brad Lincoln) and one Golden Spikes Award winner (Melendez). In addition to that, Allen was named the 2021 National Assistant Coach of the Year by D1Baseball while serving as the pitching coach and recruiting coordinator at Texas.
 
Allen’s career has included stops at USC, Texas, Tulane, Sam Houston, Florida International, Houston and Ohio State – a hire that was considered No. 4 among D1Baseball’s Top 20 Assistant Coach Hires. Just two after receiving that honor, Allen was named to the top 100 Assistant Coaches Athletic Directors Should Know by D1Baseball.
 
Allen comes to Beaumont after spending the previous two seasons at Southern Cal where he produced one of the most feared pitching staffs in all of baseball and helped guide the Trojans to a 83-39 (.680) overall record and a 38-22 (.633) conference mark. The Trojans’ 2026 pitching staff ranked second nationally in hits per nine innings, fourth in earned run average and WHIP, 27^th in strikeouts per nine innings and led the Big Ten in opponent batting average. This coming on the heels of the 2025 season where Allen helped lead USC to its first postseason appearance in a decade. The 2025 USC pitching staff finished top 30 nationally in WHIP and top 35 in hits per nine innings and strikeout-to-walk ratio. The Trojans had four pitchers named All-Big Ten that season to go along with an All-American and an MLB sixth-round draft selection.
 
Allen moved to the City of Angels from Ohio State following a two-year stint as the Buckeyes’ Associate Head Coach and Pitching Coach. The Buckeyes won 30 games his first season in Columbus and the team’s earned run average improved by nearly a full run per game. Despite his brief time at Ohio State, Allen produced multiple all-conference pitchers to go along with two MLB draftees.
 
Allen joined the Buckeye’s staff after six seasons at Texas where he showed his versatility as a coach. Starting out as the hitting coach and recruiting coordinator during his first three seasons before taking over as the pitching coach in 2020,  the Longhorns made three College World Series and four NCAA Regional appearances during that time.
 
During his three seasons as the Longhorns’ pitching coach, six Longhorn pitchers were selected in the MLB Draft – including 2020 All-American and fifth round selection Bryce Elder who is currently a member of the Atlanta Braves’ starting rotation and a former MLB All-Star – and eight position players (during his time as hitting coach).
 
In 2022, the Texas pitching staff ranked 26th nationally and led the Big 12 with a 4.22 ERA enroute to a second-straight College World Series appearance. The 2021 season saw Texas come just one game shy of the CWS Final. Under Allen’s guidance, Longhorn pitchers compiled the nation’s best ERA of 2.93 in 2021. The front end of Allen’s staff was led by a pair of All-Big 12 starters, the Big 12 Conference Pitcher of the Year Ty Madden and Tristan Stevens, and the back end of the bullpen was secured by the Freshman All-American duo of Aaron Nixon and Tanner Witt.
  
During his three seasons as Texas’ pitching coach, six Longhorn pitchers were selected in the MLB Draft, and during his three seasons as the UT hitting coach, eight position players were selected. Additionally, with Allen heading up the recruiting efforts, the Longhorns’ produced three top-10 ranked recruiting classes including the nation’s No. 1 class (2020).
 
Allen has also made coaching stops at Florida International, Tulane and his alma mater Houston where he was a standout on the diamond leading the Cougars to three consecutive postseason appearances including a Super Regional.
 
Married to the former Stephanie Beyelia – who was a standout for the UH soccer team – Allen received his bachelor’s degree from Houston in 2001.
