Ken Boyer (May 20, 1931 - September 7, 1982) was an American third baseman and manager in Major League Baseball who played primarily for the St. Louis Cardinals. Winner of the 1964 National League MVP Award, he became the second player at his position to hit 250 career home runs, and retired with the third highest slugging average by a third baseman (.462). His 255 homers as a Cardinal are a team record for right-handed hitters, and rank second in club history to teammate Stan Musial's 475. A five-time Gold Glove Award winner, he also led the NL in double plays five times and retired among the all-time leaders in games (6th, 1785), assists (6th, 3652) and double plays (3rd, 355) at third base.
A native of Liberty, Missouri, Boyer was one of fourteen children, and two of his brothers also played in the major leagues: older brother Cloyd was a pitcher for the Cardinals in the early 1950s, and younger brother Clete became a third baseman for the New York Yankees and Atlanta Braves. Three other brothers played in the minor leagues.
