After pitcher A.J. Burnett has surgery Friday to repair a broken orbital bone, the Pirates should have a better idea of when — or if — their standout right-hander might return to spring training camp. Burnett was struck near his right eye by a batted ball Wednesday during a bunt drill. Assisted by an athletic trainer, Burnett seemed to be dazed as he left the field with a towel pressed against his face. He then flew to Pittsburgh, where team doctors determined surgery was necessary. The Pirates did not provide specific information about Burnett's injury or treatment. General manager Neal Huntington on Thursday left Pirate City without speaking to reporters and was unavailable for comment later, as he attended a charity golf tournament.
