According to Jayson Stark, Cole Hamels will undergo surgery to remove "loose bodies" in his pitching arm.
As he notes, Hamels had a "sore shoulder" towards the end of the season, but he took only minimal time off.
It's probably not too serious or he would not have pitched, but as the Phillies get older, more of these types of injuries occur. Placido Polanco and Hunter Pence are also bothered by sports hernias and may need attention this offseason as well.
