Cleveland designated hitter Travis Hafner may need right shoulder surgery after an end-of-the-season physical exam.

"The strength in his shoulder was not what we had hoped it would be," GM Mark Shapiro said Tuesday. "It was a little bit disappointing. Progress was not as great as we would have hoped to have seen."

Hafner spent more than three months on the disabled list with a strained shoulder.

"I'm not trying to skirt the issue," Shapiro said. "It [the shoulder] didn't end up exactly where we would have hoped it would end up physically."
