Jason Vargas (2-8, 8.75 ERA) had been the listed starter, but Callaway announced the change Wednesday. DeGrom is starting Wednesday afternoon’s game against the Cincinnati Reds. His start against the Yankees will be on normal rest.
DeGrom leads the majors with a 1.85 ERA but is 5-7 because of the Mets’ lack of run support in his starts.
Monday’s game at Yankee Stadium is the makeup of a game postponed due to rain on July 22.
