Hefner underwent Tommy John surgery on Aug. 28, 2013, roughly two months before Harvey’s procedure.
Hefner and Harvey have both told reporters they would like to pitch for the Mets this season.
“That’s my goal,” Hefner said last month (ESPN, May 7). “That’s my hope. Hopefully I can come and contribute if there’s a need. I think I’d be wasting my time if I wasn’t trying to get back to the big leagues.”
Harvey recently told SI.com that he wants to make five to seven starts for the Mets this season.
