Luis Peralta played 2 seasons for the Rockies. He had 1 win, 3 losses, an ERA of 6.03 and 30 strikeouts.

Colorado designated him for assignment last week. The Cards had an open 40-man spot and have optioned Peralta to Triple-A Memphis, so no corresponding moves are necessary.

Peralta, 25, is the younger brother of Freddy Peralta. The younger sibling was a starter earlier in his career but got moved to a relief role when he was a minor leaguer with the Pirates. He showed tremendous promise in that role in 2024, the year he was traded to the Rockies in a one-for-one swap for Jalen Beeks.

Between the two clubs, he tossed 47 2/3 minor league innings that year, allowing only 0.94 earned runs per nine. He did give out walks at a high rate of 11.2% but his 40.1% strikeout rate was massive and his 48.8% ground ball rate above average as well. He also got to make his big league debut and put up a 0.73 ERA in 12 1/3 innings.

Things have been going downhill since then, however. He had a 9.47 ERA in the majors last year and a 9.09 ERA at the Triple-A level. For Albuquerque, his 28% strikeout rate was still pretty good but his 15.4% walk rate way too high. In the majors, things were even worse, as his ghastly 17.8% walk rate was higher than his 15.8% strikeout rate. He began 2026 back at Triple-A but but allowed 14 earned runs in 7 1/3 innings while walking 13 opponents.

His velocity is down a bit as well. His four-seamer averaged 95 miles per hour in 2024 but dropped about half a tick last year and is now down to 93.5 miles per hour so far in 2026. His curveball and changeup have had similar drops.
