The Seattle Mariners are bringing a homegrown talent into their coaching staff, announcing the hiring of Washington native Tanner Swanson as the team’s new bench coach ahead of the upcoming season.

For Mariners fans, there is something especially satisfying about seeing a Washington state native step into one of the most important roles in the dugout. The bench coach works closely alongside the manager on in-game strategy, lineup decisions, and keeping the clubhouse focused — making Swanson’s local roots a feel-good storyline as the organization looks to build on recent seasons.

The move signals the Mariners’ commitment to thoughtful roster-building both on the field and in the coaching ranks. Bringing in someone with ties to the state adds a layer of personal investment to the role — Swanson will be coaching in front of a fanbase that, in a very real sense, is his home community.

Details about Swanson’s full coaching background were not immediately available, but the announcement has already generated excitement among Mariners supporters eager to see what the new staff configuration will bring when the 2026 season gets underway.
