Key Storylines
- Pitching matchup: Eduardo Rodriguez will get the start for Arizona in this game. He is 4-7 and has a 5.53 ERA. But he looks like Nolan Ryan compared to Rockies starter Bradley Blalock. Blalock is 1-3 and has a 7.68 ERA. His struggles could benefit the Diamondbacks in this contest.
- Key Players: Hunter Goodman is the spark plug for the Rockies offensively. But he will need to have a great game to offset the contributions from players like Ketel Marte and Geraldo Perdomo for the Diamondbacks.
- Recent team streaks: The Rockies have lost five straight games. The Diamondbacks have gone 3-2 in their last five games. They snapped a two-game losing streak with their win over the Rockies on Friday.

Final Thoughts
The Arizona Diamondbacks have been inconsistent this season. But being inconsistent is better than being consistently bad. That is what the Rockies have been this year. Colorado is 55 games below .500 heading into this matchup. I think that the Diamondbacks should win rather comfortably in this contest. I recommend laying the runline with the D-Backs at a much better price than their moneyline. Eduardo Rodriguez should be able to outperform Blalock and allow the offensive talent gap to show here.
