Senga allowed just two base runners in the first 5 1/3 innings before racing to cover first on CJ Abrams’ grounder to Pete Alonso. Senga made a leaping grab of Alonso’s high throw and touched the bag with his right foot on his way down.

Kodai Senga exited his start against the Nationals on Thursday at Citi Field in the sixth inning after appearing to injure his right hamstring while covering first base.

The Mets will have their ace on the mound in Kodai Senga, who boasts a National League-best 1.59 ERA, to go along with a 6-3 record and 65 strikeouts in 68 innings.

Nimmo became the third Met to go yard in the fifth, when he took an Irvin changeup deep to left-center to push the lead to 4-0.
