After nearly 30 years with Missouri baseball, former head coach and current pitching coach Tim Jamieson will step down following the 2025 season, according to D1Baseball.
As head coach of the Tigers for 22 seasons, Tim Jamieson established himself as one of the program’s best, recording 698 wins, earning two Coach of the Year honors and leading Missouri to nine NCAA Regionals. He stepped down after the 2016 season, finishing with the second-most wins in school history.
During those 22 seasons, he coached some of the best talent Missouri has ever produced, including MLB stars Ian Kinsler, Max Scherzer, Pete Fairbanks and Tanner Houck.
After stepping down as head coach, Jamieson took some time away from the game before returning in 2020 as the pitching coach for Southern Illinois, where he spent two seasons. He then left to become the pitching coach at Memphis under current Missouri head coach Kerrick Jackson.
While at Memphis, the two helped lead the Tigers to their first winning season since 2017. That success contributed to Jackson being named Missouri’s head coach in 2024, and he brought Jamieson with him as pitching coach.
Jamieson’s decision to step down comes after a season in which Missouri recorded just three conference wins and posted a team ERA over 9.00 — the worst in the SEC. The pitching staff also ranked last in the conference in hits allowed, home runs allowed, walks, WHIP and saves.
Injuries played a major role, as nearly every pitcher on the roster missed time at some point. As a result, Jamieson was often forced to overuse arms, rely on pitchers who weren’t ready or use players in unfamiliar roles.
However, Jamieson’s departure leaves a vacancy on a coaching staff in need of major changes following the 2025 season. Missouri will begin that overhaul in 2026 with the hiring of a new pitching coach.
