Leading off the bottom of the fourth inning, Pete Alonso smashed his 42nd home run of the season -- setting the Mets single-season record.
He passes Todd Hundley and Carlos Beltran, who each hit 41 home runs in 1996 and 2006, respectively.
Mike Piazza is the only other Mets player to have hit 40 home runs in a season, as he exactly 40 homers in 1999.
In the top of the second inning, Mets CF Michael Conforto missed a diving catch, but recovered just in time to throw the ball to the cutoff man.
Amed Rosario then made the relay throw to third base, and Todd Frazier tagged out Javier Baez just in time.
