Lowder is scheduled to start Thursday's game against the Astros in Cincinnati.
The 22-year-old right-hander will stick around with the big club for at least one more turn through the rotation after making his MLB debut this past Friday versus Milwaukee in the second game of a doubleheader. He struck out six batters across four innings against the Brewers, giving up one earned run on two hits and four walks. Though he issued four free passes in his debut outing, control had been a strong suit for Lowder across his three stops in the minors this season, as he had walked just 5.4 percent of the batters he faced.
