Mariners vs Rockies Prediction

We’ve been fading the Rockies all season long and there’s no reason to stop now as they’re one of the worst teams in the history of the sport. Blalock has allowed 32 hits and 30 runs in his last 22 innings. It’s historically bad, folks. The Mariners are inching closer toward an AL West title, and they should look to take advantage of the worst team in baseball. The only option here is to side with the Mariners, and of course I’ll lay the RL to shave down the juice.
