Ralph Branca is perhaps best remembered for one infamous relief appearance in a 1951 NL playoff game at the Polo Grounds against the crosstown rival New York Giants. Branca entered the game in relief of Don Newcombe in the bottom of the ninth inning with one out and Whitey Lockman on second base and pinch runner Clint Hartung on third base and surrendered a walk-off home run known as the Shot Heard 'Round the World to Bobby Thomson, giving the Giants the pennant and the win to Larry Jansen.
