The Rockies actually jumped out to a 1-0 lead on a Todd Helton RBI single in the first, but that didn't last long. Aaron Cook (3-8, 5.82 ERA) saw Dexter Fowler turn a Gerardo Parra single into a two-run triple in the third inning and the Justin Upton followed with an RBI ground out.
Chris Iannetta showed a more aggressive approach at the plate and drove in a run during the fourth inning, one of his three hits. Yet, the Diamondbacks answered right back with a three-run home run by Miguel Montero in the fifth inning. The D'Backs led 6-2 at that point. Aaron Hill's infield single an inning later added another run.
A Kevin Kouzmanoff RBI single in the eighth inning and a Dexter Fowler home run (1) in the ninth brought the Rockies' run total to four. In between that, though, Justin Upton hit a two-run home run for the Snakes' eighth and ninth runs.
D'Backs rookie Wade Miley (2-1, 3.94 ERA) allowed just two runs over six innings before handing things over to his bullpen.
The Rockies (64-72, 29-39 away) close out the series with Esmil Rogers on the mound. First pitch is scheduled for 7:40 p.m. MT.
