The Mets headed to Denver, where a series opener against the Rockies was threatened by a forecast of 2 to 3 inches of snow on the Thursday overnight followed by a game-time temperature projected at 37 degrees. “I think we made them aware that we weren’t going to hit on the field tomorrow,” Rojas said. A steady rain began about 11 a.m. Thursday and was forecast to last all afternoon. The matchup between deGrom and Philadelphia’s Zach Eflin was called off about 50 minutes before the 12:10 p.m. EDT start. New York rescheduled the rainout as part of a doubleheader on June 25 at 4:10 p.m. Both games will be scheduled for seven innings as part of pandemic rules.
