Trevor Coleman will return to Mizzou as a graduate assistant coach this season, his second in that role. Coleman is one of the most recognizable names and faces from some of the most winningest teams in program history as he was a standout for Tim Jamieson and the Tigers from 2007-09. Coleman was the team's catcher and one of the top hitters during his time with Mizzou, amassing a 116-66 overall record over his three seasons. He helped the 2007 team win 42 games and host the NCAA Regional round at Taylor Stadium. He again helped the Tigers to 39 wins and a Regional the following year in 2008.

Coleman was the 2007 Big 12 Freshman of the Year and a Louisville Slugger Freshman All-American after hitting .282 in 49 games, tallying nine homers, 11 doubles and 42 RBI. He then hit .295 in 2008 and .260 in 2009 before being drafted by the Seattle Mariners in the ninth round of the 2009 First Year Player Draft.

During his career with the Tigers, he caught Major Leaguers Aaron Crow, Rick Zagone, Kyle Gibson and Nick Tepesch. He will assist the Tiger batters in his current role as graduate manager and will also work with the Tiger catchers.
