New York Mets starting pitcher Kodai Senga exited Thursday’s 4-3 win against the visiting Washington Nationals with a strained right hamstring.

Manager Carlos Mendoza confirmed after the game that the major leagues’ ERA leader is headed for the 15-day injured list. Senga will have an MRI on Friday to determine the severity of the injury.

“We’ve just got to wait and see what we’re dealing with,” Mendoza said.

With one out in the sixth inning, Senga raced to cover first base on a grounder by CJ Abrams. First baseman Pete Alonso fielded the ball but made a high throw as Senga covered the bag.

Senga leaped to corral the ball and landed awkwardly on the bag for the out but immediately went down in foul territory. He was holding his right leg and exited the game after a brief consultation with Mendoza and a trainer.

Senga allowed just one hit, walked one and struck out five. The Mets held a 4-0 lead when he exited the contest.

Senga, 32, improved to 7-3 with the win and his 5 2/3 scoreless innings lowered the right-hander’s ERA to an MLB-best 1.47.
