Miami Marlins vs. Colorado Rockies Prediction

I’m on the Marlins in this game. I get the case to be made for the Rockies as a home dog as they’ve been respectable in some of Gordon’s recent starts. However, Gordon still has had his fair share of issues at home, and the Rockies are still the Rockies in my eyes. Miami is still up and down and Alcantara has some ugly road numbers, but I think he can be good enough here to guide Miami to the win in this one. Give me the Fish.
