Rockies Snag Castaño, Shuffle Roster

0:00It's April 21st. Welcome in. This is MLB News Today, where the game meets AI. I'm Cory with the story. The Colorado Rockies just snag right-handed pitcher Blas Castanio off waivers from the Seattle Mariners. They wasted no time optioning him down to AAA Albuquerque to make room on the roster. This move comes right after the Mariners designated Castanio for assignment about a week back, clearing space for their own tweaks. In the corresponding roster shuffle, the Rockies put lefty Luis Peralta on waivers by designating him for assignment 2, keeping that 40 man. Roster balanced. No big stats or backstory dropped yet, but these swaps show Colorado's always hunting for bullpen arms amid the grind. Expect more details soon, as both teams settle these transactions and preseason ramps up.
