Rays vs Mariners Prediction

The Rays are 5-1 in their last 6 meetings against the Mariners but have lost their last four visits in Seattle.

In this Rays vs Mariners Prediction, the Mariners are coming as -115 home favorites. This is by far the best pitching matchup across all of today’s game as Logan Gilbert will go up against Drew Rasmussen. Both pitchers have a combined 6.37 ERA and both have a sub-1.00 WHIP, so I expect a pitchers’ duel and a low-scoring game today. The Rays were 6-1 to the under in their 7 games before playing against the Rockies in Coors Field, while the Mariners’ offense has been struggling lately, with just 3.1 runs per game in their last 5. On top of that, the Mariners have a top-10 bullpen ERA, so everything sets up for a low-scoring affair today. Take the under 7 in this one.
