Rockies vs Marlins Prediction

We have no idea what we’re going to get from Alcantara night to night, but it doesn’t matter. Another Rockies game, another chance to fade one of the worst teams in baseball history. I’ve been saying it all season, and it’s paid off all year. You should be blindly fading the Rockies, as a $100 bettor is down more than $3,500 on the season. The Rockies are all-time bad, and betting against them all year has made you some nice coin. Don’t stop now. Give me the Marlins and the RL for max betting value.
