ST. LOUIS -- New York Mets ace Jacob deGrom was scratched from Tuesday night's start against St. Louis because he was having trouble getting loose as he started to stretch ahead of his outing.
"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.
DeGrom is undergoing an MRI, according to Rojas, with results expected early Tuesday evening.
"I saw him before coming to the field and he was stretching, trying to feel his right side a little bit, and that's when we started discussing whether he's going to start or not.
