Rays vs Giants Prediction

The Rays are 5-2 in their last 7 meetings against the Giants, and are 3-1 in their last 4 meetings in San Francisco. Under is 6-4 in their last 10 meetings.

In this Rays vs Giants Prediction, the Giants are coming as -130 home favorites. Both pitchers might look similar on paper, but their home/away splits are completely opposite. Roupp has been excellent at home for the Giants with a 1.80 home ERA, and he had been in amazing form before his injury in late July, as he had a 4-1 record and a 1.42 ERA in his last five starts. On the flip side, Boyle has been terrible on the road for the Rays, with a 6.89 road ERA, and he has been torched in his last two road starts, with 10 earned runs across 6.2 innings pitched. The Giants have a better bullpen, are better against righties and are playing their third straight series at home, so I expect them to get the bounce-back win today.
