Michael Pineda has been on the DL with shoulder tendinitis since his final start in spring training. He will take a big step toward recovery this week though as he is expected to throw his first bullpen since the injury on Tuesday, according to George King of the NY Post.
Already Yankees manager Joe Girardi has ruled out the possibility of Pineda pitching in April, but beyond that little is known about his possible return. Once he pitches a bullpen we will start to get a better idea of what is going to happen. It seems realistic to expect that even without any setbacks it could take up to six more weeks for him to return so late May/early June is more reasonable.
