Given an extra day of rest due to the postponement of Game 4 until Tuesday, the Houston Astros will instead start Lance McCullers Jr. against the Chicago White Sox, the team announced.
Game 4 of the American League Division Series was originally scheduled for Monday afternoon, but it was postponed until Tuesday because of rain in the forecast.
Jose Urquidy had been Houston's scheduled starter for Monday's game, but manager Dusty Baker instead will look to close out the series with McCullers, who was dominant in Game 1 while holding Chicago without a run in 6 2/3 innings.
The Astros lead the best-of-five series 2-1.
White Sox manager Tony La Russa said he will stick with Carlos Rodon in Game 4 on Tuesday, with Game 1 starter Lance Lynn available out of the bullpen.
La Russa said Lynn or Lucas Giolito would start a potential Game 5 Wednesday at Houston depending on how things go Tuesday.
