MIAMI — With his first swing of the night, Jacob deGrom hit the ball farther than any of the Miami Marlins hit it against him.

Often they failed to connect at all.

DeGrom clubbed a homer and struck out a career-high 14 in seven shutout innings to help the New York Mets beat Miami 6-4 Wednesday night and complete a three-game sweep.

DeGrom (2-0) allowed three hits, walked one and ended his streak of five consecutive losses to the lowly Marlins. Only one Miami runner reached second base against him.

“Tonight was probably the best I’ve felt in a long time,” deGrom said.

That’s quite an admission, considering he’s the reigning NL Cy Young Award winner.

“He just does the same thing every time,” Mets manager Mickey Callaway said. “You look up at the end and it’s something really impressive. He probably has the best stuff in all the major leagues, maybe for a long time. What he’s doing is historic.”

The Mets nearly wasted deGrom’s latest gem. They took a 6-0 lead into the ninth, but Miami eventually brought the tying run to the plate.

The Mets held on, and headed back for their home opener at Citi Field on Thursday against Washington with a 5-1 record.

“You want to come out of the gates playing good baseball,” deGrom said, “and hopefully continue to do that all year.”

DeGrom extended the NL’s longest active scoreless streak to 26 innings and allowed less than four runs for the 31st consecutive start, extending his big league record. Miami was the last team to score more than three against him — last April 10.

DeGrom had made eight starts versus the Marlins since his most recent win over them on July 6, 2016. He’s 5-6 against Miami, which has beaten him more than any other team.
