The Rockies optioned Gordon to Triple-A Albuquerque on Tuesday.
The right-hander has been up in the majors for the past month, but he'll return to Triple-A after giving up 12 earned runs with a 20:4 K:BB across 17 big-league innings. Gordon could return to the rotation at Albuquerque, where he had a 2.76 ERA and 0.99 WHIP in three starts to begin the season.
