When Newcombe was pitching in the ninth inning of the third game of the playoff with the New York Giants on October 3, 1951, Erskine and Ralph Branca were warming up in the bullpen. On the recommendation of pitching coach Clyde Sukeforth, who thought that Branca had better stuff, Newcombe was relieved by Branca, who then gave up the game-winning home run to Bobby Thomson. Whenever Erskine was asked what his best pitch was, he replied, "The curveball I bounced in the Polo Grounds bullpen in 1951."
