Giants' Whisenhunt Has Torn UCL, Likely Needs Tommy John Surgery

The Giants announced that pitcher Carson Whisenhunt has a torn UCL and will likely need Tommy John surgery, ending his season — and then, as if the baseball gods were making a point, a second starter exited that same night with a throwing arm injury of his own, per Maria Guardado of MLB.com.

Two nights, two starters

The second starter's situation is still developing. He departed in a scene Guardado described as similar to Whisenhunt's, but the nature and severity of the throwing arm injury has not been detailed. What remains unconfirmed: any diagnosis, timeline, or IL move connected to that exit.

For Whisenhunt, the picture is clearer and considerably grimmer. The club's announcement follows a sequence that unfolded over recent days — he was placed on the IL with a left elbow injury, underwent an MRI, and awaited consultation with team doctors before the torn UCL finding and the likely surgery recommendation came through.

The broader context

San Francisco was already navigating a crowded injury ledger. Willy Adames was placed on the IL in the same stretch, and the Giants posted an unconventional lineup featuring Rafael Devers at first base and Jung Hoo Lee at DH — a configuration that read less like a strategic choice and more like a roster doing its best under the circumstances.

On a lighter note, Carson Seymour recorded his first career MLB save recently, a reminder that the bullpen has been asked to carry weight while the rotation absorbs these losses.

What to watch

The second starter's update is the immediate open thread. Any diagnosis, IL placement, or roster move connected to that exit would be the next piece of this story. The Giants have not announced anything further on that front.
