In 2007, Braun had what some sportswriters called one of the most dominant rookie seasons in baseball history. Called up on May 24 by the Brewers, he hit his first major league home run two nights later. Braun was voted the National League (NL) Rookie of the Month for June, ranking first in RBIs (21) and tied for first in home runs (6) among NL rookies that month. He also recorded a .716 slugging percentage and a .435 OBP. In July, Braun became the fastest in Brewer history to hit 10 major league home runs, doing so in his 38th game. He hit his 15th home run in the 50th game of his career, and his 20th in his 64th game, making him the fastest to those milestones since Albert Pujols in 2001. He was also the fastest to 20 homers in Brewers history. At month's end, he received his second consecutive NL Rookie of the Month Award, as well as his first NL Player of the Month Award (making him the first player to have won both awards in the same month). He hit a league-leading 11 home runs, with 25 RBIs, while batting .345.
