Cuas' contract was selected by the Royals on Monday.
Cuas was promoted to Triple-A Omaha late in 2021, and he began the 2022 season in Omaha after serving as a non-roster invitee this spring. Over 23 relief appearances at the Triple-A level, the 27-year-old has posted a 1.40 ERA and 0.97 WHIP in 25.2 innings. The right-hander hasn't yet made his major-league debut but will provide assistance in the bullpen after the Royals placed several relievers on the COVID-19 injured list Monday.
