Harvey was designated for assignment by the Rockies on Tuesday.
Harvey had his contract selected over the weekend but has been removed from the 40-man roster without appearing in a game. If he clears waivers, the right-hander should return to Triple-A Albuquerque, where he has a 2.63 ERA, 1.59 WHIP and 20:9 K:BB over 13.2 innings.
