Mariners Expand Edgar Martinez's Role, Add Experienced Hitting Coach Kevin Seitzer

The Seattle Mariners are making significant changes for the 2025 season by expanding Edgar Martinez's role to oversee the hitting program. Alongside him, the Mariners will hire experienced hitting coach Kevin Seitzer and Bobby Magallanes as the assistant hitting coach. Martinez's Hall of Fame experience is expected to play a crucial role in developing the team's offensive capabilities. Dipoto emphasized the need for a creative approach, allowing Martinez to guide hitters without the demands of a full-time schedule. Seitzer, with a decade of experience from the Atlanta Braves, is anticipated to greatly benefit the Mariners' hitters.

The organization aims to improve performance, particularly for players like Julio Rodríguez, who have faced early-season struggles. These appointments signal an exciting transition for the Mariners as they prepare for a more successful season ahead.
