The Royals selected Sisk's contract from Triple-A Omaha on Friday.
Sisk had been set to hit minor-league free agency, but the Royals will prevent that from happening by adding him to their 40-man roster. The left-handed reliever put up a 1.57 ERA and 81:26 K:BB over 57.1 innings this season at Omaha. Sisk could make his major-league debut during the 2025 season.
