40-year old Rockies first baseman Jason Giambi becomes the second oldest player in history to hit three homers in one game. Stan Musial set the record in 1962 when he went yard three times as a 41-year-old. Giambi only appeared in 64 games and hit 13 homers during the 2011 season. Giambi is a five time All-Star and was the AL MVP in 2000 and the runner-up in 2001. His 440 career home runs is currently 41st all-time.
