Alex Rodriguez became the youngest player in MLB history to reach 400 career home runs at 29 years and 316 days old. The right-handed slugger launched two homers in a 12-3 victory over the Milwaukee Brewers to move into 39th all time for career longballs. Rodriguez broke the record previously set by Ken Griffey Jr., who reached the mark at age 30 years and 141 days old.
