Giants vs Rays Prediction
The Rays are 7-2 in their last 9 meetings against the Giants and are 4-1 in their last 5 meetings in Tampa.
In this Giants vs Rays Prediction, the Rays are coming as -125 home favorites. Both teams are coming into this matchup in opposite trajectories, as the Rays are red-hot with a 8-1 record in their last 9 games, while the Giants have lost five straight. I don’t trust either pitcher in this matchup, as they both have a 10.16 ERA combined and their home/away split are even worse. Both teams are better against the opposing starter throw hand with 8.8 runs/9 combined and the Rays rank 22nd in bullpen ERA, so I expect a high-scoring affair today. Take the over 8 runs in this one.
