position Associate Head Coach/Pitching Coach/Co-Recruiting Coordinator

Sean Allen joined Bill Mosiello’s staff in July of 2022. He will serve as the associate head coach and the program’s pitching coach and co-recruiting coordinator. Allen spent the previous six seasons as an assistant coach at Texas.

Allen served on David Pierce’s staffs for 11 seasons at Texas, Tulane and Sam Houston State. Allen was Texas’s hitting coach and recruiting coordinator from 2017-19 and transitioned to the role of pitching coach in 2020 and remained the Longhorns’ recruiting coordinator. After a tremendous 2021 campaign, Allen was named the Dl Baseball Assistant of the Year.

The Longhorns advanced to the College World Series in each of Allen’s final two seasons on staff. In 2022, the Texas pitching staff ranked 26th nationally in ERA (4.22) and led the Big 12 in ERA. The Longhorns rolled through the Austin Regional and then took the final two games of the Greenville Super Regional vs. ECU to earn their trip to Omaha.

The 2021 season saw Texas return to the College World Series and come just one game shy of the CWS Finals. Under Allen’s guidance, the Longhorn pitching staff compiled the nation’s best ERA of 2.93. 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. Madden finished the year with a 2.45 ERA, a 7-5 record and 137 strikeouts in 113.2 innings pitched. Stevens led the Big 12 with 11 wins and finished with a 3.31 ERA in 111.1 innings. The backend of the bullpen was secured by the Freshman All-American duo of Aaron Nixon and Tanner Witt. Nixon led the Longhorns with nine saves and had a 2.12 ERA with 35 strikeouts in 34 innings. Witt went 5-0 with five saves, a 3.16 ERA and 73 strikeouts in 57 innings pitched.

The pitching staff flourished under Allen during the shortened 2020 season, compiling a 2.59 ERA with 168 strikeouts in 153 innings. Junior RHP Bryce Elder was named to the shortened-season Collegiate Baseball Newspaper All-America second team and freshman LHP was named as a Freshman All-American by Collegiate Baseball Newspaper.

In 2018, Allen helped the Longhorns to a .271 batting average, a .431 slugging percentage, and 62 home runs, the highest marks for a Texas team in the BBCOR era. With help from Allen, second baseman Kody Clemens produced one of the most impressive offensive seasons in Longhorns history to earn unanimous first team All-America honors. Additionally, under Allen’s guidance, the Longhorns’ 2018 recruiting class ranked No. 9 by Perfect Game.

The Carlsbad, N.M., native went to Austin with 15 years of coaching experience at the collegiate level. While at Tulane, he was Pierce’s lead recruiter, playing a major part in leading Tulane to NCAA Regional appearances in both of his seasons in New Orleans.

In addition to recruiting, Allen worked primarily with hitters and infielders. Under his guidance, the Tulane offense pounded out 66 home runs to lead the American Athletic Conference and rank 13th in the nation in 2016. Tulane had three players hit double-digit home runs in a single season for the first time since 2005, while leading the AAC in slugging percentage (.423) and ranking second in runs scored (355), RBI (324) and walks (258).

Five hitters earned all-conference honors, including shortstop Stephen Alemais, who became a 2016 All-AAC First Team selection and a third-round pick (No. 105 overall) of the Pittsburgh Pirates in this year’s Major League Baseball Draft.

Prior to Tulane, Allen served as an assistant coach with Pierce at Sam Houston State for three seasons. There, he helped the Bearkats to three straight Southland Conference titles, while receiving NCAA Regional berths in each of those seasons. In 2014, the team ranked 25th in the nation and second in the conference in hits (610). It also led the conference in scoring (5.7 rpg), home runs (31) and slugging percentage (.390).

From 2008 to 2011, Allen served as an assistant coach at Florida International University, where he was recruiting coordinator and pitching coach and assisted with the infielders. Allen helped the Panthers put together a 130-103-1 record, while also earning NCAA Regional berths in 2010 and 2011 and capturing the Sun Belt Conference title in 2010.

In his first full season as pitching coach in 2009, Allen was instrumental in turning around FIU’s staff. After finishing at or near the bottom of the Sun Belt in 2008 in various categories, his tutelage turned the Panthers’ staff into one of the conference’s best. For most of 2009, FIU led the conference in ERA, while the Panthers finished with the lead in strikeouts and surrendered the fewest walks with a single-season school record low of 88.

Allen’s coaching career began as a student assistant with Houston in 2002 where he worked with the UH infield and coached first base. He spent the next five seasons as an assistant coach with the Cougars, helping guide UH to NCAA Tournament appearances in 2002, 2003 and 2006.

As Houston’s hitting and infield coach, Allen played a major role in the offensive development of Brad Lincoln, a consensus All-American who was named the National Player of the Year by four different outlets in 2006. That same season, Allen’s lineup hit 71 home runs, the fifth-highest total in UH single-season history, while batting .314 and slugging .544.

A four-year letterman with the Cougars from 1998 to 2001, Allen concluded his playing career as UH’s all-time leader with 542 assists. During that time, the Cougars competed in an NCAA Super Regional and advanced to NCAA postseason play in three consecutive seasons.

Allen earned his bachelor’s degree in sports administration from Houston in 2001. He is married to the former Stephanie Beyelia, a former soccer standout at UH.
