Harmon Clayton Killebrew ( June 29, 1936 – May 17, 2011), nicknamed "Killer" and "Hammerin' Harmon'", was an American professional baseball first baseman, third baseman, and left fielder. During his 22-year career in Major League Baseball (MLB), he played for the Washington Senators who later became the Minnesota Twins, and for the final season of his career, the Kansas City Royals. When he retired, he was second only to Babe Ruth in American League (AL) home runs and was the AL career leader in home runs by a right-handed batter (since broken by Alex Rodriguez). He was inducted into the National Baseball Hall of Fame in 1984.
Killebrew was a stocky 5'11" tall, 213-pound hitter with a compact swing that generated tremendous power. He became one of the AL's most feared power hitters of the 1960s, hitting 40 home runs in a season eight times. In 1965, he played in the World Series with the Minnesota Twins, who lost to the Los Angeles Dodgers. His finest season was 1969, when he hit 49 home runs, recorded 140 runs batted in (RBI), and won the AL Most Valuable Player Award. Killebrew led the league six times in home runs and three times in RBIs, and was named to eleven All-Star teams.
