The 1946 World Series was played in October 1946 between the St. Louis Cardinals and the Boston Red Sox. This was the Red Sox's first appearance in a World Series since their championship of 1918.

Theodore Samuel Williams was an American professional baseball player and manager. He played his entire 19-year Major League Baseball (MLB) career, primarily as a left fielder, for the Boston Red Sox from 1939 to 1960; his career was interrupted by military service during World War II and the Korean War. Nicknamed "Teddy Ballgame", "the Kid", "the Splendid Splinter", and "the Thumper", Williams is widely regarded as one of the greatest hitters in baseball history and to date is the last player to hit over .400 in a season. His .482 on-base percentage is the highest of all time.
