A's right-hander Jarrod Parker injures his elbow yet again (Yahoo Sports)

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.
