Tim notices a tweet from Duke Welker:
At Andrews institute ready for surgery for my new elbow. Probably wouldn’t be tweeting normally but these meds make everything sound great.
Welker has not pitched since May 3. If he's having Tommy John surgery, he'll likely be out until the middle of next season, by which point he'll be 29. Welker has a good arm, but has never really delivered on its promise, and this appears to be another setback for him. He remains on the Pirates' 40-man roster.
