Colorado Rockies vs. Arizona Diamondbacks Prediction

I’m on the over in this game. These are just two starting pitchers I don’t trust, and while Lorenzen’s been better on the road, he just got tuned up by Arizona in his last start. Gallen’s been very hittable this season and has been one of the lesser arms from an effectiveness standpoint in this rotation, and I think the over is where it’s at in this one. Give me the over.
