New York Mets first baseman Pete Alonso hit his 27th home run of the season on Sunday to set the franchise rookie homer record.
Alonso's homer in the top of the fourth inning off the Chicago Cubs' Cole Hamels traveled 454 feet to center field. The home run is tied for his second longest this season.
Darryl Strawberry had held the Mets' record for home runs by a rookie when he hit 26 in 1983.
He had set the National League mark for home runs before the All-Star break with his 26th home run on Saturday.
