New York Mets ace Jacob deGrom could return to the mound against the Arizona Diamondbacks on Sunday.
DeGrom was diagnosed with inflammation in his right lat following an MRI on Tuesday, though the star pitcher avoided the injured list having been shut down for the "next few days".
The two-time National League (NL) Cy Young Award winner was scratched from his scheduled start against the St Louis Cardinals on Tuesday before the MLB showdown was postponed due to inclement weather.
The Mets open a three-game series against the Diamondbacks on Friday.
"I was a little bit more sore after my last start. Didn't think too much of it," DeGrom said on Wednesday.
"I noticed my mechanics were off. Looked at some of the video and got some of the numbers, and my arm was down a little bit and ... flying open. So that's obviously going to put more stress on my arm."
"Feeling good now. The plan is to see the doctor again tomorrow and let him re-evaluate," DeGrom said. "It's in a good spot, I guess. If it kind of creeps up towards the armpit, then it's not good, but the spot it's in is definitely manageable."
DeGrom is boasting an MLB-best 0.51 ERA through his five games in MLB in 2021.
The three-time All-Star has allowed 16 hits, five runs and just two homers for the Mets, while he has struck out 59 batters.
DeGrom tied Nolan Ryan's record for most strikeouts through a pitcher's first five starts of a season.
The 32-year-old tallied nine strikeouts over six innings against the Boston Red Sox last month to improve his five-game total to 59, matching Ryan's feat in 1978.
DeGrom also ranks first for strikeouts per nine innings (15.17) among pitchers this season.
