The Royals made the Hunter Renfroe signing official today, and to make room for him on the 40-man roster, they designated pitcher Max Castillo for assignment. The right-handed pitcher was acquired in 2022 from Toronto with Samad Taylor in exchange for Whit Merrifield.
The 24-year-old Castillo appears in parts of the last two season with the Royals as a long reliever and spot starter. In 39 innings he had a 6.69 ERA with 27 strikeouts and 19 walks, including a 4.43 ERA in seven relief appearances this year.
The move caps off a whirlwind of activity on the roster. To recap:
RHP Matt Sauer
LHP Will Smith
RHP Seth Lugo
RHP Chris Stratton
RHP Michael Wacha
OF Hunter Renfroe
RHP Dylan Coleman (traded to the Astros)
RHP Collin Snider (claimed off waivers by the Diamondbacks)
RHP Taylor Clarke (traded to the Brewers)
OF Edward Olivares (traded to the Pirates)
RHP Jonathan Heasley (traded to the Orioles)
RHP Max Castillo (designated for assignment)
Castillo could still be traded within seven days, or re-signed to a minor league deal if he clears waivers.
