Harmon Clayton Killebrew Jr. (June 29, 1936 – May 17, 2011), nicknamed "the Killer" and "Hammerin' Harmon", was an American professional baseball player as a first baseman, third baseman, and left fielder. He spent most of his 22-year career in Major League Baseball (MLB) with the Minnesota Twins. A prolific power hitter, Killebrew had the fifth-most home runs in major league history at the time of his retirement. 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. Killebrew was inducted into the National Baseball Hall of Fame in 1984.
Killebrew was 5 feet 11 inches (180 cm) and 213 pounds (97 kg). His compact swing generated tremendous power and made him one of the most feared power hitters of the 1960s, when he hit at least 40 home runs per season eight times. In total Killebrew led the league six times in home runs and three times in RBIs, and was named to 13 All-Star teams. In 1965, he played in the World Series with the Twins, who lost to the Los Angeles Dodgers.
