Trejo was optioned to Triple-A Albuquerque on Sunday, Patrick Saunders of The Denver Post reports.
EDGE Analysis
Trejo mainly operated as a depth option for the Rockies early in the season, but he recently drew four consecutive starts. He appeared in 10 games and hit .257 with a homer, a double, six runs and six RBI, but he'll be demoted since Colorado will activate Garrett Hampson (hand) from the 10-day injured list Tuesday.
