A spectacular pitching duel highlighted the night as the Rockies ended up losing 2-1 on a Diamondbacks walk-off single.
The Amazing Agnos Making his first start since high school, Zach Agnos was incredible on the mound. Coming into the game, the Rockies were hoping to get at least four innings out of Agnos, but got much more than that. Showing command of all his pitches, Agnos kept the Diamondbacks off balance as he worked quickly and efficiently, firing 71 pitches, 49 for strikes, over five innings of work while collecting four strikeouts and allowing just one walk, just the third Rockie all-time to have that stat line in his first career start.
He also induced three groundouts and six flyouts. The baserunner for Arizona didn’t come until Adrian Del Castillo drew a one-out walk, and the lone hit Agnos gave up was a soft line drive by Ketel Marte with two outs in the same inning. While it wouldn’t have been great for him to get more run support and leave with a lead instead of a 0-0 tie, the fact that he matched the veteran Eduardo Rodriguez pitch-for-pitch through five innings is a major feather in his cap and may warrant another start in five days.

Corbin Carroll then grounded into a force out, thanks to a nifty play by Chad Stevens, that drove in the run to give the Diamondbacks a 1-0 lead.
