Colorado Rockies vs. Arizona Diamondbacks Prediction
I’m on the over in this game. I just think that while Quintana is one of the better starting options the Rockies have, he’s still a lefty going against an Arizona team that’s raking against southpaws right now. On the other side, Ryne Nelson’s really struggled at home this season and I think that he gets tagged here as well so I’m rolling with the over in this one.
