The Rockies optioned Justice to Triple-A Albuquerque on Thursday.
Justice will head back to the minors just four days after joining the big club and recording one out in his season debut Sunday. The 26-year-old southpaw owns a 9.90 ERA through 20 innings at Albuquerque, though he's surrendered just one earned run across his last six minor-league appearances. Jaden Hill was selected from Triple-A in a corresponding move.
