Tampa Bay Rays vs Seattle Mariners Prediction
Kirby has been solid for the Mariners this season, but it’s the Rays who have been the far and away more consistent team. Jax has also been slightly sharper with a 3.63 ERA and 1.21 WHIP. The Rays are just one of those teams that isn’t sexy with casual bettors, and you can get them at favorable prices despite them winning a good percentage of their games. The value will continue to be with the Rays at these price points, so that’s where I’m going to land.
