April 21, 2025 8:10 PM : Castillo (adductor) recorded two strikeouts across a scoreless inning Saturday after Triple-A Reno activated him from its 7-day injured list.
Analysis: Castillo began the season on the IL due to left adductor tightness, but he's since been given the green light to return to the mound. He entered spring camp as a non-roster invitee for Arizona before going down with the injury, so he could be an option for a mid-season promotion if he pitches well at Triple-A.
