Rays vs Mariners Prediction
I’m on the over in this one here. I get the case to be made for either side in this game, but I think we’re getting some runs here. Kirby has had issues at times on the road, and we know how hitter-friendly Steinbrenner Field has been this season. On the other side, Adrian Houser’s been shaky at times and had issues in his lone home start as a Ray, and we’ve seen two high-scoring affairs already in this series. Give me the over.
