PORT ST. LUCIE, Fla. -- Left-handed reliever Josh Edgin underwent Tommy John surgery late last spring training. And the New York Mets are eyeing a May 1 return to the majors.

Right now, Edgin is looking to get over a mental hurdle in his rehab process from the ligament-replacement procedure. Edgin is currently throwing fastballs off a mound -- although at less than full throttle -- at Mets camp. He is trying to tune out thinking about his elbow, because doing so is affecting his mechanics.

Edgin suggested that his arm was "lagging behind" during a session off a mound at Mets camp on Monday.

"I was beating myself in the head last night because I'm not getting extension, because I'm thinking about my elbow," Edgin said. "It's something we need to fix."

Once off the disabled list, Edgin will join Jerry Blevins as the left-handed specialists in the Mets bullpen. Edgin had a 1.32 ERA and lefty batters hit .185 in 65 at-bats against him in 2014.

"I just got hitters out," Edgin said, recalling that season. "I was having a good run at it. ... That was so long ago."
