MESA, Ariz. -- Trying to come back from a series of elbow injuries, Oakland pitcher Jarrod Parker hurt his elbow yet again on the 12th pitch of a simulated game Thursday.
The A's said Parker, who came off the field in pain, suffered a lateral elbow impingement Thursday and will undergo an MRI exam.
Parker had Tommy John surgery in March 2014 and was slowed by a broken elbow last year. The right-hander, who twice had the ulnar collateral ligament reconstructed in his pitching arm, was nearing his return from that second Tommy John surgery last season when he was injured while on a rehab assignment with Triple-A Nashville.
