Manny Acta, Perry Hill, Kevin Seitzer and Eric Young Jr. will not return to the Seattle Mariners’ coaching staff in 2027, the club announced Monday after Dan Wilson’s tenure as manager ended. The vacancies could let a prospective manager shape the staff.
Acta had spent 11 years as an active coach in Seattle, making him the staff’s longest-tenured member. Infield coach Hill was credited by J.P. Crawford and Dylan Moore with significant contributions to their Gold Glove awards. Few in the clubhouse or around the league appeared to view Seattle’s league-worst 2026 defense as a coaching problem rather than a reflection of the players’ limitations.
Seitzer became hitting coach in 2025; Seattle’s 2026 offense was inconsistent, with power numbers falling without gains in batting average or other areas. Young Jr. was the first-base coach. No pitching or bullpen roles had changed, and Pete Woodworth, Trent Blank, Danny Farquhar, Austin Nola, Fleming Báez and Justin Novak may return. Hitting Coordinator Ed Paparella and Senior Director of Hitting Strategy Edgar Martinez appear safe.
