Some expected injury news became official this week.
The Oakland A’s announced Wednesday afternoon that pitcher Deolis Guerra underwent successful right elbow ulnar collateral ligament reconstructive surgery.
The reliever missed the Cactus League this spring due to forearm tightness, and then began the regular season on the 60-day injured list this month. It was already announced two weeks ago that he would have surgery, with the dreaded Tommy John operation seeming likely based on the clues, and indeed that proved to be the answer. More details:
The surgery was performed today at the Texas Metroplex Institute Surgical Center in Arlington, Tex.
