Giants vs Nationals Prediction

The Giants are 7-3 in their last 10 meetings against the Nationals and are 6-1 in their last 7 visits in Washington.

In this Giants vs Nationals Prediction, the Giants are coming as -155 road favorites. The giants have won both games in this series and are now facing a struggling Miles Mikolas, who has given up 17 total runs in his three starts this season. On the flip side, Robbie Ray has not given up more than 2 runs in any of his four starts this season and the Nationals rank 28^th in bullpen ERA. Even though the Giants rank 26^th in runs per game, they have scored 17 in the two games of this series and I expect them to keep rolling against a struggling pitcher and a terrible bullpen.
