Rockies Acquire Castaño, DFA Peralta

0:00On April 21st, the Colorado Rockies just scooped up right-hander Blas Castanio off waivers from the Seattle Mariners. Both teams made the announcement, and in a matching move, the Rockies designated lefty Luis Peralta for Simon. They optioned the 27-year-old Castanio straight to triple A Albuquerque to bolster their pitching death. Castanio signed with the Yankees out of the Dominican Republic back in the day, got released in 2023, and the Mariners grabbed him. Quick, he showed promise last year with a 4.3A earned run average over more than 120 minor league innings, mostly in the tough Pacific Coast league. He's got a solid ground ball rate around 46% and mixes five pitches, leaning on his 94-mile per hour sinker, slider, cutter, and change up. Mariners added him to the 40-man roster last November, but only used him once in the majors. Rockies love that versatile arm, especially with their pitching woes. Now, on Peralta, the 25-year-old came over from the Pirates in last year's deadline deal.

1:03He lit it up in 2024, with a sub-one earned run average in the minors and even flashed in the Biggs. But this year, he struggled hard, posting over nine earned run averages everywhere with Sky High Walks. Rockies are hurting for arms after the worst staff ERA and baseball last season, but they're improving a bit at 4.40 early on. Castanio gives them flexibility as a starter or reliever down the road. While Peralta hits waivers, teams might still see upside if they can fix his. Control. Keep an eye on these depth pieces shaking up the farm. Stay tuned with MLB News Today, AI-powered updates.
