En route to a very likely National League Rookie of the Year Award, Cody Bellinger set a historic mark on Friday night. He smashed a three-run homer off Jeff Samardzija for his 39th big fly of the season, surpassing Frank Robinson and Wally Berger for the most home runs ever by an NL rookie.
Berger originally set the mark with 38 home runs for the Boston Braves in 1930. Robinson also hit 38 homers when he won the National League Rookie of the Year in 1956.
For 57 years that was the overall rookie home run record until Mark McGwire hit 49 as a rookie with the A's in 1987.
