Grandstand Managers Night was a Major League Baseball (MLB) promotion in which fans in attendance to a St. Louis Browns game at Sportsman's Park collectively made managerial decisions for the team. The game occurred on August 24, 1951, with the Browns defeating the Philadelphia Athletics by a score of 5–3. While 3,925 fans were in attendance, only 1,115 sat behind the Browns dugout to partake in the promotion with double-sided placards reading "yes" and "no" for voting purposes. It is the only known instance of spectators making managerial decisions in an official MLB game.
