A day after losing a doubleheader to the San Francisco Giants, the Mets received a double whammy: Left fielder Jason Bay and right-hander Mike Pelfrey are headed to the disabled list. Bay suffered a non-displaced fracture of a rib on his left side while attempting a full-extension catch in Game 2 of Monday's doubleheader, on a deep shot by Gregor Blanco.Pelfrey, for now, is diagnosed only with right elbow inflammation. Still, general manager Sandy Alderson said ligament damage has not been ruled out, meaning Tommy John surgery could be forthcoming. A major league source, however, said that team officials are aware Pelfrey has a partial tear of the ulnar collateral ligament and team officials are bracing to lose him to season-ending surgery."It's frustrating to lose a doubleheader one day and two players the next," Alderson said.The Mets also had placed backup infielder Ronny Cedeno on the disabled list before Monday's doubleheader with a strained intercostal muscle on his left side.
