Rockies Claim Sammy Peralta From Brewers

The Rockies have claimed left-hander Sammy Peralta off the Brewers’ waiver wire, Todd Rosiak of the Milwaukee Journal Sentinel reports.  Colorado has officially announced the move, and shifted right-hander McCade Brown to the 60-day injured list to create space for Peralta on the 40-man roster.  Peralta has been optioned to the Rockies’ Triple-A affiliate.

The Brew Crew designated Peralta for assignment earlier this week to open up a 40-man roster spot for the newly-acquired Luis Matos.  Peralta’s tenure with the Brewers will end after two Triple-A appearances and zero big league games, as Milwaukee just claimed Peralta off waivers from the Angels last October.

Appearing in each of the last three MLB seasons, Peralta’s resume in the Show consists of 30 appearances and 45 2/3 innings with the White Sox and Angels from 2023-25.  He has a 5.12 ERA, 17.3% strikeout rate, and 11.2% walk rate, and Peralta has averaged only 89.3mph on his fastball during his brief time in the majors.

Peralta drastically cut back on his fastball in 2025 and also cut back on his changeup usage, instead incorporating a sinker a third of the time and boosting his slider up to a 49% usage rate, without any real change in results.  While his ERA jumped from 4.80 in 2024 with the Sox to 7.59 with the Angels in 2025, Peralta’s underlying metrics didn’t change much, so his change in pitch repertoire didn’t have any impact on his performance either under the hood or in terms of bottom-line results.

Peralta routinely pitches multiple innings in relief, making him a useful depth option for the Rockies’ bullpen.  Brennan Bernardino is also the only left-hander in Colorado’s current relief mix, which could give Peralta some extra opportunity to stick with the team if and when he is eventually called up from Triple-A.

Brown started the season on Colorado’s 15-day IL due to shoulder inflammation, and the move to the 60-day IL ensures that his 2026 debut won’t come until at least the last week of May.  2025 marked Brown’s first taste of the big leagues, as he posted a 7.36 ERA over 25 2/3 innings and seven starts for the Rockies.
