He had a 17.18 ERA for Triple-A Albuquerque in six appearances in 2026 before the Rockies designated him for assignment.

Rockies designated LHP Luis Peralta for assignment.

It clears room on the 40-man roster for Blas Castaño, who was claimed off waivers from the Mariners on Tuesday. Peralta will now hit the waiver wire, and if he goes unclaimed, he’ll likely report back to Triple-A Albuquerque.

Rockies optioned LHPs Carson Palmquist, Luis Peralta and Welinton Herrera, RHP Gabriel Hughes and OF Sterlin Thompson to Triple-A Albuquerque.

Palmquist, 25, appeared in nine games for the Rockies in 2025 where he compiled an uninspiring 8.91 ERA and 2.04 WHIP across 34 1/3 innings. Given the Rockies’ overall lack of pitching depth, he’ll probably get another shot at the big league level at some point during the 2026 season.

Rockies placed LHP Luis Peralta on the 15-day injured list, retroactive to September 8, with left hip inflammation.

The Rockies were taking things day-to-day with the 24-year-old southpaw but it got to the point where they couldn’t afford to play short-handed any longer. Ryan Rolison was recalled from Triple-A Albuquerque to take his place in the Rockies’ bullpen.
