In baseball, "Shot Heard 'Round the World" is an epithet used to describe a game-winning home run by New York Giants outfielder and third baseman Bobby Thomson off Brooklyn Dodgers pitcher Ralph Branca at the Polo Grounds in New York City on October 3, 1951, to win the National League pennant. Thomson's dramatic three-run homer came in the ninth inning of the decisive third game of a three-game playoff for the pennant in which the Giants trailed, 4-2.

This Rawlings official National League baseball was signed in blue by both Branca and Thomson, with Thomson inscribing, "Oct. 3, 1951." This baseball includes a Great Moments COA.
