Castro has put together a .241/.304/.295 slash line with a home run and 11 RBI over 45 games this season for Triple-A Oklahoma City. He last surfaced in the big leagues during the 2018 campaign, though his stay lasted just 18 contests. He figures to be assigned to Triple-A Tacoma following Sunday's transaction and will serve as organizational depth.

Castro has found success early in the spring and is now 3-for-8 with three RBI and two runs scored. Although he's a long shot to break camp with the big-league team, he could see time in the majors if the Dodgers are bitten by the injury bug at any point during the regular season.

Castro has spent parts of three seasons in the majors but has very little to show for it, posting a .210/.240/.265 line in 98 games. He's unlikely to earn a roster spot in Los Angeles this spring but has the versatility to cover anywhere on the infield should injuries strike the team.

Castro appeared in 18 games for the Rockies this season but didn't do much with the opportunity, hitting a meager .174/.191/.261. His weak .210/.240/.265 career line won't make him a hot commodity on the waiver wire. Garrett Hampson's contract was selected in a corresponding move.
