Diamondbacks vs Rockies Prediction
The Diamondbacks are 6-3 in their last 9 meetings against the Rockies and have won their last two visits in Colorado.
In this Diamondbacks vs Rockies Prediction, the Diamondbacks are coming as -160 road favorites. The Dbacks need every win they can get to keep their wild card hopes alive but I don’t trust Merrill Kelly and his 5.00 ERA and 1.47 WHIP. On the flip side, Mason Adams has terrible numbers this season and has been weaker at home, so I expect a high-scoring affair at Coors Field today. The Dbacks are 3-1 to the over in their last 4 games and have scored 20 runs across their last three games, so I expect them to do most of the heavy lifting and push this game over the total.
