The Royals acquired Hoffman from the Phillies on Monday in exchange for Manuel Colon.
Hoffman had been booted off the Phillies' 40-man roster earlier Monday, but he'll now join a new 40-man roster in Kansas City. The right-handed reliever has logged a 4.72 ERA and 40:18 K:BB over 34.1 innings at the Triple-A level this season and has given up two runs in 4.2 frames in the majors in 2026.
