The Mets scored seven unearned runs in the eighth inning to break open a tie game. New Jersey Gov. Chris Christie was in attendance with his family while on vacation.
While facing Matt Clark with two outs, Medlen threw an off-speed pitch, grabbed his right elbow and turned his back to home plate. He then removed himself from the game.
Medlen, picked to start on opening day, was examined by Mets physician Dr. Struan Coleman and diagnosed with a right forearm strain pending an evaluation back at the Braves’ complex on Monday.
Medlen was 15-12 last year with a 3.11 ERA in 197 innings for the NL East champions. The 28-year-old right-hander had Tommy John surgery in 2010.
“Obviously, any time a pitcher walks off the mound and meets you at the foul line, you worry about that stuff,” Braves manager Fredi Gonzalez said. “But after everything kind of settled down, we’re optimistic it’s nothing really major.”
Gonzalez said he talked to Medlen briefly during the pitching change and again inside the clubhouse afterward.
“He wasn’t in good spirits. But after he got settled down a little bit and the trainers looked at him, I thought he was in better spirits,” Gonzalez said.
Medlen did not speak with reporters but relayed a message that he will be available Tuesday in Orlando.
Braves catcher Evan Gattis said Medlen had good stuff through three innings.
“He was executing pitches, and the next thing you know — I don’t know what he grabbed — but I knew it was his arm. It’s never a good sign, never a good feeling, to be out there and see a pitcher walk off the mound like that,” Gattis said. “On the last pitch, he just threw a yanked changeup — I’ve never seen that — and immediately there was a problem. ... He was throwing good pitches, and then it was just an out-of-the-blue kind of thing.”
