William Charles Schuster (August 4, 1912 – June 28, 1987) was an American professional baseball player who played shortstop in the Major Leagues from 1937 to 1945. He would play for the Pittsburgh Pirates, Boston Bees, and Chicago Cubs.
Schuster scored the winning run in the Chicago Cubs' last victory in a World Series game, prior to 2016. He was a pinch-runner in the 11th inning of Game 6 at Wrigley Field in the 1945 World Series and scored from first base on Stan Hack's walk-off double for an 8-7 Cub win over Detroit. It turned out to be Schuster's last appearance in a Major League game.
