The Tri-Cornered Baseball Game was a three-way exhibition baseball game held at the Polo Grounds on June 26, 1944, among the Brooklyn Dodgers, New York Giants and New York Yankees. The game, a World War II fundraiser, was played with a round-robin format in which each team batted and fielded during six innings and rested for the other three. The Dodgers won by scoring five runs in their times at bat; the Yankees scored one run, while the Giants were unable to score.
