Rockies Make Roster Moves Ahead of Series Against Diamondbacks

As the Colorado Rockies gear up for their three-game series against the Arizona Diamondbacks, they announced several roster changes on Thursday afternoon. The most notable move is the placement of outfielder Brenton Doyle on the Injured List due to a left oblique contusion, an injury he sustained while making a diving catch in Tuesday’s game.

To fill Doyle’s spot, the Rockies have called up Chad Stevens, who has been on a hot streak with the Albuquerque Isotopes. In 168 plate appearances, Stevens has boasted an impressive slash line of .362/.435/.523, resulting in a .958 OPS. The 27-year-old infielder has also showcased his speed on the bases with six stolen bags. Originally drafted by the Houston Astros in 2021, Stevens made his big league debut with the Los Angeles Angels last season and has continued to impress since signing with the Rockies as a minor league free agent in the offseason.

In addition to these changes, the Rockies recently recalled Blas Castaño from Triple-A Albuquerque. Castaño made his presence felt in the bullpen, pitching 2.1 innings and allowing just one earned run on two hits, while striking out three and walking one. His ability to provide bulk innings aligns well with the Rockies’ current strategy to rely on versatile relievers.

In a corresponding move, left-handed pitcher Sammy Peralta has been optioned back to Albuquerque. Peralta served as an opener for Tanner Gordon in Tuesday’s game but struggled, failing to record an out in the first inning.

Lastly, the Rockies designated lefty Carson Palmquist for assignment. This season has been challenging for Palmquist, who has compiled a 7.20 ERA over 25.0 innings, yielding 12.6 hits per nine innings. Originally selected in the third round of the 2022 draft, Palmquist made his MLB debut last season but faced difficulties, posting an 8.91 ERA in nine appearances, including seven starts, with 25 walks and 27 strikeouts.
