topshefAccording to Bart Hubbuch of the New York Post, Gary Sheffield expects to undergo an MRI exam either today or tomorrow.   Following last afternoon's 6-2 win over the Yankees, Sheff said he's feeling pain behind his right knee. Sheffield is hitting .261/.381/.478 (BA/OBP/SLF) with 7 home runs and 24 RBI in 134 at bats this season. After his second consecutive game with a home run, can the Mets afford to send Gary to the DL?
