The SF Giants are trying to assemble their coaching staff under new manager Tony Vitello, and as they do so they are losing coaches under the previous staff to other teams. The latest departure is first base coach Mark Hallberg.
Hallberg is leaving the Giants to become the bench coach of the Minnesota Twins under new manager Derek Shelton. This comes after J.P. Martinez, San Francisco's pitching coach for the 2025 season, left to become the bullpen coach of the Atlanta Braves.

While close confidants of Bob Melvin like third base coach Matt Williams and bench coach Ryan Christenson seemed like obvious departures, Martinez and Hallberg seemed like two candidates with a decent likelihood to return.
