Rays vs Mariners Prediction

The Mariners are 4-1 in their last 5 head-to-head meetings against the Rays, but the Rays are 6-4 in their last 10 overall meetings. Over is 5-3-2 in their last 10 meetings.

In this Rays vs Mariners Prediction, the Mariners are coming as -125 home favorites. The Mariners are rightfully favored, as they have a better overall record, and have been strong at home, while the Rays are below average on the road. Evans has been excellent at home for the Mariners with a 3.03 ERA, while Boyle has two shutouts in his three starts this season, and he is coming off a shutout start against the Dodgers. Both teams have top-10 bullpens this season, and yesterday’s game had only 5 total runs. I like another low-scoring affair in this one, so take the under 8 runs.
