If I'm the owner, the question is when will he back surgery vs rest? Obviously you don't want to perform surgery on healthy body...
That said, what I'm afraid is we wait and situation isn't improved and have the surgery in October. Then his 2022 season is shot and probable return of summer of 2023.
If he has surgery today, he'll be back summer of 2022.
I guess as long as he's not accumulating major league time, his absence won't really matter, unlike Sale where he's under major league contract and he's getting paid.
