The Yankees have known since Sunday that lefty starter Nestor Cortes was going to need a stint on the injured list. The only question was the extent of the damage on his shoulder, and how they would manage their roster in the meantime.
Cortes received a cortisone injection on Tuesday, and after an MRI, the team officially diagnosed him with a strained left rotator cuff. Considering how dangerous shoulder injuries can be, it could’ve been a lot worse, but the lefty will still need to rest for two weeks before he can throw again.
