The Colorado Rockies announced Saturday afternoon that they had claimed left-handed reliever Sammy Peralta off waivers from the Mikwaukee Brewers.
The Rockies have optioned Peralta to the Triple-A Albuquerque Isotopes.
Peralta, 27, is not related to left-handed reliever Luis Peralta, who is also currently in Albuquerque. He was originally selected by the Chicago White Sox in the 18th round of the 2019 draft out of the University of Tampa. He made his big league debut with the White Sox in 2023 and posted
a 4.37 ERA over 45 2/3 innings across parts of two seasons with 37 strikeouts and 24 walks.
Since 2024 Peralta has spent time with multiple organizations—including several individual stints with the White Sox—and was briefly called up by the Los Angeles Angels in 2025. Over five appearances with the Angels he yielded 12 runs—nine earned—over 10 2/3 innings with eight strikeouts and six walks.
Peralta utilizes a mix of five pitches, none of which average more than 89 MPH: a slider, a sinker, a changeup, a four-seam fastball, and an occasional sweeper.
To clear space on the 40-man roster, right-handed pitcher McCade Brown has been moved to the 60-day injured list.
Brown, 25, made his MLB debut directly from Double-A last season. He posted a 7.36 ERA over seven starts and struck out 23 batters through 25 2/3 innings. Brown missed the entirety of spring training with right shoulder inflammation. He was most recently schedule to throw batting practice against live hitters on March 28th.
The Rockies’ 40-man roster is currently full.
