The Royals recalled right-hander Jake Junis from Triple-A Omaha on Tuesday, optioning righty Michael Maness to Omaha in a corresponding move.
Junis, who will start Tuesday night's game against the Astros, will be making his second career big league start after allowing two runs in 4 2/3 innings in a no-decision at Minnesota on May 21. The 24-year-old is 1-0 with a 2.70 ERA in three appearances for the Royals this season.
Junis has performed admirably in his seven starts for the Storm Chasers, going 2-2 with a 2.34 ERA while ranking seventh in the Pacific Coast League with 57 strikeouts across 42 1/3 frames.
Maness, 28, is 1-0 with a 3.72 ERA in eight appearances for the Royals in 2017.
