A quite literally a heavy hitter, Ortiz is one of the greatest sluggers baseball has ever seen. Big Papi terrorized the American League as member of the Boston Red Sox and while he slimmed down a little for his final season at age 40, Ortiz was always one of the heavier ball players out there. But it never stopped him from crushing home runs and helping the Red Sox reverse the curse back in 2004.
