The D-backs got on the board first, with an A.J. Pollock sacrifice fly, but Chase Anderson struggled out of the gates, allowing a two-run homer to Nolan Arenado in a three-run first. The Diamondbacks did get one back in the second, on Chris Owings' RBI single, and Anderson settled down thereafter. He worked through five innings with no further damage, scattering eight hits and no walks, with five strikeouts. Arizona then took the lead in the top of the sixth, tying things up on an Owings' double, and going ahead on an RBI groundout by Ender Inciarte. But a one-run lead at Coors Field is so flimsy, it might as well not be anything at all.
Randall Delgado did work a scoreless sixth, but didn't retire a batter in the seventh, leaving with the bases loaded and no outs. The newly-recalled lefty specialist Keith Hessler faced one batter... and allowed a grand-slam, giving the Rockies a three-run lead. Another September call-up, Matt Stites proved little better, allowing four hits and two runs in the eighth, and Colorado cantered away to leave Arizona ruing what might have been, but for two late blown leads in Denver. Owings got three hits, there were two apiece by David Peralta and Jake Lamb, and Brandon Drury did get his first knock in the major-leagues.
