Seattle Mariners vs Colorado Rockies Prediction
I’ve been fading the Rockies all season long, and you should probably continue over the next week. However, I’m not sure what the Mariners have done to deserve to be favored with their disappointing act. For what it’s worth, Sugano is 2-0 in two career games against the Mariners with a 1.46 ERA. Outside of the Mets, the Mariners are the biggest letdown in baseball this season. Nothing to play for on either side; I’ll take a stab with the Rockies and the plus money.
