For the fourth game, Toronto threw Morris against Oakland's Bob Welch. In the second inning, Olerud tagged Welch for an opposite-field homer to give the Jays the lead. However, the Athletics came back in a big way with a five-run third and tacked on another run in the sixth when Sierra doubled Rickey Henderson home, giving Oakland a seemingly secure 6–1 advantage. In the top of the eighth, however, La Russa pulled Welch, who had been cruising along, and went to his bullpen. The Jays capitalized by scoring three runs off hits by Joe Carter, Olerud, and Maldonado, cutting the A's lead to 6–4.
