New York Mets first baseman Pete Alonso hit his 40th home run of the season on Sunday to set the National League rookie record for home runs in a season.
Alonso homered to left field in the ninth inning. The 418-foot blast off the Kansas City Royals' Jacob Barnes broke a tie with the Los Angeles Dodgers' Cody Bellinger for most home runs by a NL rookie in a season.
Bellinger hit 39 home runs in 2017.
Alonso is the first Mets player to hit 40 home runs since Carlos Beltran in 2006.
