1951 Major League Baseball season

The 1951 Major League Baseball season opened on April 16. Teams from both leagues played a 154-game regular season schedule. At the end of the regular season, the National League pennant was still undecided resulting in a three game playoff between the New York Giants and the Brooklyn Dodgers. After splitting the first two games, the stage was set for a decisive third game, won in dramatic fashion on a walk-off homerun from the bat of Giant Bobby Thompson, one of the most famous moments in the history of baseball, commemorated as the "Shot Heard 'Round the World" and "The Miracle at Coogan's Bluff". The Giants would go on to lose the 1951 World Series to defending champion New York Yankees, who were in the midst of a 5-year World Series winning streak.
