The Royals selected Gose's contract from Triple-A Omaha on Thursday.
Gose has spent the entire season at Triple-A, where he owns a 4.94 ERA, 1.57 WHIP and 59:31 K:BB across 47.1 innings. Although his performance has been unremarkable, the 36-year-old will now return to the big leagues for the first time since 2024 to give Kansas City's bullpen a fresh arm, replacing Mason Black.
