Las Cucarachas The Rockies (57-67) head to the desert to take on Arizona (62-63) for the last time this season in the start of a three game set. Chi Chi Gonzalez takes the mound for the Rockies, his first after allowing five runs on eight hits over five innings in San Diego on August 10.
Zac Gallen is making his third start for the Dbacks after coming over from Miami for Jazz Chisholm. (Fun fact: this was the second time he was traded, after the Cardinals trade him to Miami with Sandy Alcanterra for Marcel Ozuna).
