Top pitching prospect A.J. Puk might be done for the season after it was recommended Tuesday that the left-hander undergo Tommy John surgery, the A’s announced.
Dr. James Andrews recommended that Puk have surgery to repair the ulnar collateral ligament in his left arm. Puk consulted Andrews after an initial diagnosis by Dr. Doug Freedberg in Arizona, the A’s said in a release.
It was deflating news for the A’s, given Puk’s prominence and the timing. The team announcement came during the second inning of its final spring training game Tuesday night at AT&T Park.
