Smith will serve as an opener Saturday in Game 1 of the ALDS against the Guardians, James Fegan of the Chicago Sun-Times reports.
Smith tossed three scoreless frames in Game 1 of the wild-card series versus the Astros, and the White Sox will turn back to the lefty Saturday on three days' rest. The lefty will be capable of covering multiple innings against Cleveland, if needed, but it will be a bullpen game for the White Sox.
