LOS ANGELES -- To make room for pitcher Brandon McCarthy on the active roster, the Dodgers on Sunday optioned Brock Stewart to Triple-A Oklahoma City before the series finale against the Rockies at Dodger Stadium.
The move to make room for McCarthy on the 40-man roster hasn't yet been announced.
McCarthy on Sunday makes his first major league start since April 25, 2015. He had Tommy John surgery five days later.
The Dodgers plan to start Julio Urias against the Orioles Monday, on five days rest, followed by Kenta Maeda and Bud Norris on regular rest, leaving Stewart the odd man out.
Stewart made his major league debut on Wednesday in Milwaukee, allowing five runs in five innings in a loss to the Brewers. Stewart was victimized by a pair of big hits in a five-run second inning, allowing a three-run home run to Kirk Nieuwenhuis and a two-run double to Ryan Braun. But he also struck out seven and walked two, and didn't allow a run in his other four innings.
It was the culmination of an amazing rapid rise for Stewart, who started the year in Class-A Rancho Cucamonga and was promoted twice in the minors before getting the major league call. The 24-year-old right-hander, drafted by the Dodgers in the sixth round in 2014, is 8-3 with a 1.47 ERA in 14 minor league starts this season, including 3-0 with a 2.89 ERA in three starts with Oklahoma City, with 27 strikeouts and two walks.
