Mantle played his entire Major League Baseball (MLB) career (1951–1968) with the New York Yankees as a center fielder, right fielder, and first baseman. Mantle was one of the best players and sluggers and is regarded by many as the greatest switch hitter in baseball history.[2] Mantle was inducted into the Baseball Hall of Fame in 1974[3] and was elected to the Major League Baseball All-Century Team in 1999.
