Shohei Ohtani hurt his elbow on August 23rd and cannot pitch anymore this season. He has also been out of the lineup since September 4th because his side hurts.
Shohei Ohtani can choose to play for any baseball team after the World Series. The Angels spent money to buy new players at the trade deadline to help Ohtani win a championship for the first time and maybe convince him to stay with the Angels, but it didn't work.
