The Dbacks are 7-2 in their last 9 overall meetings against the Rockies, and are 7-1 in their 8 meetings in Arizona. Under is 6-2-1 in their last 9 meetings.

In this Rockies vs Diamondbacks Prediction, the Diamondbacks are coming as huge -340 home favorites. The Diamondbacks are rightfully favored, as they have been the superior team this season, as it was shown in a dominating shutout 8-0 victory yesterday.  The Rockies are by far the worst team in the MLB so far, and are putting one of their weakest pitchers on the mound. Gallen has been struggling to start the season for the Dbacks, but he will have no trouble against the worst team in the league. I expect another dominant Arizona win, so take the Arizona Diamondbacks on the runline.
