Coaching Staff Changes Across MLB

Seattle is hiring Yankees catching coordinator Tanner Swanson as bench coach under first-time manager Jason Kanzler. Kanzler has described an emphasis on accountability, clear expectations, and communication, but his lack of managing experience makes implementation an open question. The Dodgers’ Aaron Bates will not return as co-hitting coach in 2027; Detroit, Cincinnati, Houston, and the Athletics have also made staff or front-office changes.
