Key Storylines
Pitching Matchup
Eduardo Rodriguez is 4-7 with a 5.68 ERA and he will take the mound for the Diamondbacks. Rodriguez gave up five runs in 5.1 innings of work against the Rockies in his last start and will look to bounce back against the same opponent here.
Bradley Blalock is 1-3 with a 7.89 ERA and he will start for the Rockies. Blalock has given up 12 earned runs over 10.1 innings of work over his last two starts and he simply has to be better for the Rockies to have a chance here.
Key Players
- Arizona Diamondbacks: Ketel Marte drove in four runs for the Diamondbacks on Wednesday and will be a key factor for the Diamondbacks again.
- Colorado Rockies: Hunter Goodman is the top producer offensively for the Rockies but he hasn’t had nearly enough help this year.
Recent Team Streaks
- Arizona has won two straight games and four of their last five.
- Colorado has won two straight games over the St. Louis Cardinals coming into this series.

Final Thoughts
The Diamondbacks should be able to win this game on the road against a struggling pitcher in Blalock. But I’m not sure that I trust Eduardo Rodriguez to pitch well enough for the D-Backs for them to secure the win here. Instead of taking a side, I think it’s a better idea to bet the over in this NL West matchup. Both offenses should generate some scoring chances against inconsistent starting pitching and the struggling bullpens on both sides should help the over as well.
