Mariners vs Rockies Prediction
The Mariners are 8-1 in their last 9 meetings against the Rockies and have won two of their last three visits in Colorado.
In this Mariners vs Rockies Prediction, the Mariners are coming as -185 road favorites. The Mariners are on the verge of elimination from the playoffs, but they still have mathematical chances and are playing against a terrible Rockies team that is 1-10 in its last 10 games and are putting Gabriel Hughes on the mound with his 6.37 ERA and 1.45 WHIP. Seattle are putting Woo on the mound, who might be far weaker on the road but has just one earned run in his last three starts, so I expect them to win this one on the road. Take the Mariners on the moneyline.
