He allowed two hits and struck out six before he was replaced by Paul Sewald for the fifth inning.
Citi Field held its breath.
The Mets will hope deGrom's injury isn't a sign of things to come after getting off to a 17-10 start through their first 27 games. The team did not expect to release any information until Thursday.
Make no mistake about it, any Braves team over the last 5 years would've lost that game. But of far more importance is the fate of deGrom, their co-ace along with Noah Syndergaard. Even though deGrom said his elbow hurt, the Mets let him pitch the fourth. But Callaway said the injury didn't take his players' minds off the game. He still breaks their hearts ... but you better never say a bad word about him.
"That last at-bat he had, I could just tell something wasn't right with the swing", Snitker said.
"I think he popped into my head right away", he said. "So he went back out".
DeGrom eclipsed 200 innings for the first time in his career in 2017.
But deGrom winced in pain again when Nick Markakis roped a single back up in the middle.
DeGrom allowed two hits - both singles - and did not walk a batter. After all, he had only thrown 46 pitches. "We have plenty of options". We might have seen why Tuesday night.
Obviously, this may mean there is a chance Matt Harvey could return to the rotation. "We'll just have to talk through that".
New York Mets fans have suffered through starting pitcher injuries through the years.
"Who knows?" Callaway said.
deGrom has thrown 18 1/3 straight scoreless innings for the Mets. Flores is hitting out of the second spot against lefty Sean Newcomb. The 2015 AL MVP has played 12 games for Toronto this season, hitting three home runs with nine RBIs.
The Braves poured it on with four in the eighth against Gsellman.
Mike Soroka picked up a victory in his major league debut and the Braves pulled within a half-game of the NL East lead by downing the first-place Mets, 3-2.
Ender Inciarte, Atlanta's wondrous center fielder who has been dropped to ninth in the order through the emergence of 21-year-old Ozzie Albies and 20-year-old Ronald Acuna Jr., who now hit 1-2, doubled to start the sixth. Julio Teheran will start game three and is 1-1 with a 4.50 ERA and 29 strikeouts this season. 36 of them, in fact, would end up going for strikes.
"I'm sure I won't sleep very good", Callaway said (via the Athletic).
