Carson Whisenhunt Needs Tommy John Surgery, Seeking Second Opinion on Surgeon

Giants lefty Carson Whisenhunt reportedly knows TJ surgery is necessary and is pursuing a second opinion solely to determine who will perform the procedure.

Carson Whisenhunt's path forward is no longer a question of whether — only who.

Per Susan Slusser, the Giants left-hander is seeking a second opinion, but the purpose of that consultation is to settle on a surgeon rather than to revisit the diagnosis itself. Whisenhunt reportedly already knows Tommy John surgery is needed. As part of that process, he has spoken with Birdsong and McDonald about their own experiences going through the procedure, per Slusser's report.

What remains unresolved

No surgeon has been named, no procedure date has been reported, and no roster move has been announced. The second opinion is ongoing, per Slusser.

The broader picture in San Francisco

The Giants are navigating a crowded injury ledger. Willy Adames is dealing with a UCL sprain in his left elbow with a surgery decision still pending, and Adrian Houser exited a recent start with forearm tightness he has compared to a 2022 flexor-tendon strain — MRI results for Houser have not yet been reported. Whisenhunt's situation adds another layer to a rotation already being stress-tested.

What to watch: the surgeon decision and any corresponding roster move once the Giants move forward.
