Kodai Senga allowed one hit in 5 2/3 scoreless innings before exiting with an apparent right leg injury Thursday afternoon as the New York Mets extended their home-winning streak over the Washington Nationals to 10 games by holding on for a 4-3 victory.Senga (7-3) allowed a clean single to James Wood two batters into the contest and one other baserunner. He was injured covering first base on a grounder by CJ Abrams hit to first baseman Pete Alonso.With one out in the sixth, Senga raced over to cover first. Alonso fielded the ball but made a high throw as Senga covered the bag.Senga jumped to catch Alonso’s throw and immediately fell down. He was holding the back of his right leg and, after a brief consultation with manager Carlos Mendoza and a trainer, Senga exited the game.Senga retired 13 straight before issuing his only walk of the contest to Jose Tena in the fifth. Senga struck out five and lowered his ERA to an MLB-best 1.47.Before Senga’s injury marred New York’s sixth straight win and 13th in the past 14 home encounters with the Nationals, Jeff McNeil and Brandon Nimmo homered.McNeil hit a three-run homer into the right row of the lower right field seats in the first inning off Washington’s Michael Soroka (3-4) after walks to Francisco Lindor and Juan Soto.It was McNeil’s fifth homer in his past 11 games.
