Stewart is slated to start Wednesday against the Diamondbacks, Mike DiGiovanna of the Los Angeles Times reports.
Stewart has made three starts for the Dodgers this season, and although he tossed five scoreless innings against the high-powered Cubs last Sunday, he was sent down to Double-A afterwards. Prior to that impressive showing, Stewart surrendered 15 earned runs in 12 innings over three appearances, so he is far from a proven commodity just yet. That being said, he'll still get the call Wednesday as the Dodgers attempt to preserve the arm of 20-year-old Julio Urias.
