Stewart will start Saturday's game against Arizona, Andy McCullough of the Los Angeles Times reports.
Stewart's move back into the rotation bumps scheduled starter Bud Norris back for at least one day. Stewart will undoubtedly be fresh when he takes the hill Saturday, having last pitched on Sept. 7 when he picked up his first career win against the Diamondbacks. He'll carry a 6.55 ERA and a 1.73 WHIP into Saturday's outing.
