DeGrom underwent an MRI, which showed inflammation in his right lat. He will refrain from throwing for the next few days, the team said.
“He let us know earlier today that he had some tightness on his right side,” Mets manager Luis Rojas said about three hours before game time. “I watched him coming into the field, and he was extending, trying to sense his right side just a little bit, and that’s when we started discussing whether he’s going to start or not.”
Rojas said the issue wasn’t evident before Tuesday.
DeGrom, a two-time NL Cy Young Award winner, was baseball’s most dominant pitcher this year, with a major league-best 0. 51 ERA in five starts, 59 strikeouts in 35 innings with only four walks. Still, he’s just 2-2 as New York continues to have trouble scoring runs .
The 32-year-old right-hander has reached 100 miles on 46 of 473 pitches this season and reduced his career ERA to two. 55, overtaking Hall of Famer Tom Seaver (2. 57) since the Mets career pioneer.
Right-handed reliever Miguel Castro was to start in deGrom’s place.
