Matthew Shoemaker will be recalled from his rehab assignment three days after his first start due to a nerve issue in his right forearm, the Angels announced on Friday.
Team doctors diagnosed Shoemaker with posterior interosseous nerve syndrome following his start with Class A Advanced Inland Empire on Tuesday. The issue was treated with a cortisone shot, which will result in Shoemaker being shut down for seven to 10 days. Once his symptoms subside, he will be able to begin throwing again.
"That's disappointing," manager Mike Scioscia said. "We hoped it was something really simple, and hopefully he'll get back to the mound in a reasonable amount of time, but obviously it's not what maybe we thought it was two weeks ago. We'll have to take some time and see what's happening."
Shoemaker was originally placed on the disabled list in mid-June with a forearm strain. He pitched well in his rehab start, striking out five in three scoreless innings.
