Rockies Bolster Bullpen with Peralta, Brown Sidelined
Peralta's Arrival: A New Arm for the Rockies' Bullpen
The Colorado Rockies announced on Saturday their acquisition of left-handed relief pitcher Sammy Peralta from the Milwaukee Brewers through a waiver claim. Peralta, who is 27 years old, has been assigned to the Triple-A Albuquerque Isotopes, signaling an immediate integration into the team's minor league system. Interestingly, he shares a surname with another pitcher in Albuquerque, Luis Peralta, but the two are not related.
Peralta's Professional Journey and Performance Insights
Peralta's baseball career began when he was drafted by the Chicago White Sox in the 18th round of the 2019 draft, following his college career at the University of Tampa. He made his major league debut with the White Sox in 2023, where he recorded a 4.37 ERA across 45 2/3 innings over two seasons, tallying 37 strikeouts and 24 walks. Since 2024, Peralta has moved between several organizations, including multiple stints with the White Sox, and had a brief call-up with the Los Angeles Angels in 2025. During his five appearances with the Angels, he allowed 12 runs (nine earned) over 10 2/3 innings, with eight strikeouts and six walks. Peralta's pitching arsenal features five distinct pitches: a slider, a sinker, a changeup, a four-seam fastball, and an occasional sweeper, none of which average above 89 MPH.
McCade Brown's Injury and Roster Implications
To create the necessary space on the 40-man roster for Peralta, right-handed pitcher McCade Brown was transferred to the 60-day injured list. Brown, 25, debuted in MLB last season directly from Double-A. He posted a 7.36 ERA over seven starts, striking out 23 batters in 25 2/3 innings. Brown was sidelined for the entirety of spring training due to right shoulder inflammation and was last scheduled to throw batting practice against live hitters on March 28th. Following these roster adjustments, the Rockies' 40-man roster is currently at full capacity.
