There was a little fraying of the rotator cuff and labrum found during the surgery, but Keppinger said it was nothing more than regular wear and tear. He said that the shoulder problem never hurt him swinging, but did affect him throwing during a disappointing debut season with the White Sox.
"I had what you'd call 'chronic tendinitis,'" Keppinger said. "I would have a shot that would calm it down, but without giving it the rest, it would keep coming back. I had an inflamed bursa sac that constantly kept coming back, so they went in there to clean it out and take care of it so it would work smoothly and not be a problem next year."
