Hefner to again undergo Tommy John

NEW YORK -- Jeremy Hefner is undergoing Tommy John surgery for the second time in less


lastname Hefner than 14 months. Dr. James Andrews will perform the procedure on Thursday morning in Pensacola, Florida.

Mets doctor David Altchek performed Hefner's original procedure.
