The Rockies sent Trejo outright to Triple-A Albuquerque on Friday.
Trejo's move to Triple-A and off the 40-man roster comes as a result of Dakota Hudson signing with the Rockies on Friday. Trejo slashed .232/.288/.343 with 26 RBI across 227 plate appearances last season. However, he has historically performed significantly better in Triple-A, and he could still return to Colorado if he gets off to another hot start in the minors.
