Jacob deGrom's return from the injured list will come against the Brewers no matter what.
Whether that takes place Friday night on time, following a rain delay, or on Saturday remains to be determined.
Mets manager Mickey Callaway said that if there's a game played Friday, deGrom will be on the mound, even with a lengthy delay. DeGrom, the reigning National League Cy Young Award winner, is set to return from a brief stint on the IL due to strep throat and a minor elbow issue that led to him undergoing an MRI, which ultimately came back clean.
If the Mets and Brewers will play a day-night doubleheader on Saturday in the event Friday's game is postponed due to weather, the 30-year-old will start the first game, Callaway said.
DeGrom is 2-2 with a 3.68 ERA in four starts this season. In his first two outings, he combined to throw 13 scoreless innings. However, he has allowed nine runs, 13 hits, five walks and five home runs over nine innings in his last two starts.
He is set to face Chase Anderson, who is 2-0 with a 3.00 ERA this season.
Since the Mets have yet to formally activate deGrom off the IL, someone will have to be sent down before the game begins.
In a potential doubleheader Saturday, someone can be considered the 26th man and allow the team to demote someone to Triple-A Syracuse at the conclusion of the second game.
