The Seattle Mariners have hired Tanner Swanson to join their major league coaching staff, bringing the former New York Yankees catching coordinator back to the Pacific Northwest.
Swanson spent recent seasons as the Yankees' major league field coordinator and director of catching. His return to the Mariners organization marks a homecoming after he previously worked in their system.
The move was reported by Kate Preusser for SB Nation on November 6, 2026.
