Mike Pelfrey will be sidelined for the next 2-4 months after having surgery Tuesday to relieve pressure on his ulnar nerve. It's an operation that seems likely to end his season. Pelfrey had been on the disabled list with a groin injury, but he had to be shut down late last month due to the elbow issue. If his season is indeed over, Pelfrey will have posted a 7.99 ERA over five starts. He's under contract for $5.5 million next season.
