Shohei Ohtani required surgery for his injured left shoulder:

Before the injury, the Dodgers were hoping Ohtani could restart his throwing program earlier than usual this offseason in anticipation of him returning to a two-way role in 2025. It is unclear how this surgery, performed by Dr. Neal ElAttrache in Los Angeles, might impact the timing of that, but it was done on Ohtani’s non-throwing shoulder.

Ohtani was throwing his regularly scheduled bullpen sessions, the last step in his rehabilitation from a second major elbow surgery, leading up to the time when he was injured.

He probably should not have been playing after hurting the shoulder, but he did pick up a key catchers interference call. I always thought he should be a one-way player as a batter, but if this injury hinders his swing, he might finish his career as just a pitcher.
