Harmon Killebrew belted 573 home runs over the course of his Major League Baseball career, and on this day in 1975, he struck his 573rd and final home run. The longball was slugged in the second inning of a contest between Killebrew's Kansas City Royals and his former Club: the Minnesota Twins. The home run was good for one run, which was enough to help his Club edge out the Twins, 4-3.
