Cole Kimball will have season-ending surgery next week to repair a torn rotator cuff, a devastating blow for the rookie reliever.
Kimball had been on the disabled list since June 10 with shoulder inflammation. He attempted to resume throwing this week but continued to complain of shoulder pain, so the Nationals sent him to New York specialist David Altchek for an enhanced MRI. That test revealed a torn rotator cuff; Altchek will perform the surgery sometime next week.
A 12th-round pick in 2006, Kimball was the first member of that draft class to play for the Nationals. The 25-year-old went 1-0 with a 1.93 ERA in 12 relief appearances, striking out 11 in 14 innings.
"He just got here, and he pitched well up here," manager Davey Johnson said. "It's an unfortunate injury. Hopefully he'll be alright and recover. But that's part of the game, injuries, and we've had our fair share."
A team spokesman said Kimball would not be speaking to reporters today.
