In this Mariners vs Rays Prediction, the Mariners are coming as -140 road favorites. Kirby has finally managed to put together some good starts for the Mariners lately, but he is still weaker on the road, with a 4.73 ERA, while Houser has been better at home for the Rays, with a 2.08 ERA. The Rays have dominated the Mariners in the first two meetings and are playing better baseball. They also have a better bullpen and are better than the Mariners against right-handed pitching, so I really like them in this spot as home dogs. Take the Tampa Bay Rays and the plus money at home.
