Castro had his contract selected from Triple-A Albuquerque by the Rockies on Saturday.
Castro will be a part of the Opening Day roster after signing a minor-league contract in January with an invite to MLB spring training. The infielder will likely spell starters all around the infield, and he could see some playing time in the outfield as well. Castro will help the Rockies in 2023, but he is unlikely to help much in fantasy formats even if he gets regular playing time.
