The Rockies optioned Chivilli to Double-A Hartford on Monday.
Chivilli received his second big-league call-up of the season June 3, and over his five appearances in the majors, he gave up five runs on eight hits while striking out two over 5.1 innings. He was sent back to Double-A to clear room on the 26-man active roster and in the bullpen for right-hander Jake Bird (elbow), who was reinstated from the 15-day injured list.
