Nationals vs Rays Prediction

The Rays are 5-1 in their last 6 meetings against the Nationals and are 3-2 in their last 5 meetings in Tampa.

In this Nationals vs Rays Prediction, the Rays are coming as -140 home favorites. I like the Nationals in this one as road dogs with Alvarez on the mound, who has given up just four runs in his last three starts. On the flip side, Martinez has given up 12 runs in his last three starts, the Rays’ bullpen has been terrible and they are weaker against lefties, while going up the best offense in baseball. Give me the Nats and the plus money.
