Brennan Seiber, a 6‑foot‑6 right‑hander who spent three seasons at Vanderbilt, has officially committed to Oregon State for his senior year, bolstering the Beavers' bullpen with a wealth of experience.
A Strategic Addition for the Beavers
During his collegiate career, Seiber appeared in 58 games for the Commodores, compiling a 9‑3 record and a 4.40 ERA over 108 and one‑third innings. He capped his Vanderbilt tenure with a 2024 season in which he led the team with 23 appearances, five saves and a 3‑0 record, posting a 5.06 ERA.
The pitcher relies on a low‑slot delivery that mixes a sinker in the low‑90s with a slider in the high 70s, occasionally flashing a mid‑80s cutter. His repertoire draws comparisons to former Beavs reliever Isaac Yeager, highlighting a similar experience‑driven profile.
Seiber will join a staff overseen by new head coach Andrew Moore, who took over the program this year. Moore inherits a rotation that includes returning veterans and fresh talent, and the addition of Seiber is viewed as a key piece in restoring the Beavers' competitiveness in the Pac‑12.
