“We had numerous chances throughout the day,” Miami manager Don Mattingly said. “I thought (deGrom) did a pretty good job. Blister or not, he’s still 98, 99 (mph).”

DeGrom had a runner on base in each inning on a sun-splashed day in which his fastball velocity was slightly lower than his first three starts. His heater averaged 98.7 mph through his first three starts, and Sunday his 44 four-seam fastballs averaged 98.1 mph.

“That second inning, it was a lot of stress, a lot of pitches,” Mets manager Luis Rojas said. “Jake, he’s got the stuff to get out of an inning like that.”

Four relievers followed deGrom.

Edwin Diaz struck out Harrison to end the eighth with runners at second and third. Seth Lugo tossed a scoreless ninth for his third save.

Giménez scored on an RBI groundout by Jeff McNeil in the third after stealing second base. Giménez also doubled and scored on a base hit by Brandon Nimmo in the fourth, and came home on McNeil’s sacrifice fly in the sixth.

“We’re having fun watching him play. And this kid, he’s a sponge,” Rojas said. “Every day he’s learning more and more, and his abilities are getting better and better.”

Marlins rookie Eddy Alvarez had the first three hits of his career, stole his first base and reached four times. He also made a diving stop at second base to rob McNeil in the third and prevent a potential two-run single.
