A's right-hander Jarrod Parker injures his elbow yet again

MESA, Ariz. (AP) 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. He had another surgery for an elbow fracture May 19.

On Thursday, Parker was throwing to hitters for the first time since coming back from his latest setback.
