Giants vs Nationals Prediction

The Giants are 6-3 in their last 9 meetings against the Nationals and are 5-1 in their last 6 visits in Washington.

In this Giants vs Nationals Prediction, the Giants are coming as -120 road favorites. The Giants won yesterday but I don’t trust them with the struggling Adrian Houser on the mound, who has back-to-back games with 4 earned runs. Cavalli is also coming off his worst start of the season with 4 earned runs, but the Nationals have the third-best offense in baseball, as opposed to the Giants’ 28th. The Giants are even weaker against righties, with 2.8 runs/9, so I like Nationals in a bounce-back spot for plus money today.
