Colorado Rockies vs Arizona Diamondbacks Prediction
The Rockies continue to lose and can’t win on the road, and Agnos has been a mess with a 5.59 ERA and 1.41 WHIP. The Diamondbacks have put together a solid week and Rodriguez has been strong through 53.1 innings, where he has a 2.53 ERA and 1.26 WHIP. I have no use for the Rockies in their current form. Give me the Diamondbacks and the better pitcher on the bump. Of course I’ll lay the RL to shave down the price.
