Edgar Martinez headlines Mariners 2025 coaching hires under manager Dan Wilson

SEATTLE — The Seattle Mariners announced Tuesday their 2025 slate of coaches—with both new faces and returning staff—as the team looks to shore up an offense that came close to setting the single-season record for strikeouts.

Dan Wilson will helm the ship as the Mariners sail into next season with high hopes, a dominant pitching staff, and question marks in the infield. Wilson replaced Servais on Aug. 23 last season and has a revamped coaching staff for 2025.

Edgar Martínez, who arrived with Wilson after Scott Servais was fired, becomes senior director of hitting strategy. Martínez replaced Jarret DeHart as hitting coach in 2024.

Manny Acta returned to his Mariners bench coach job under Wilson, a role Acta held from 2018-19 under manager Scott Servais.

Acta was Seattle’s third base coach from 2016-17 and 2020-2024. He managed Cleveland from 2010-12 and Washington from 2007-09.

Kevin Seitzer was hired as hitting coach after serving in that role for Atlanta from 2015-24. Bobby Magallanes was hired as assistant hitting coach, a role he held with Braves under Seitzer for the previous four seasons.
