Phillies vs Nationals Prediction

The Phillies are 6-2 in their last 8 meetings against the Nationals and are 3-1 in their last 4 meetings in Washington.  

In this Phillies vs Nationals Prediction, the Phillies are coming as -190 road favorites. I like the Phillies in a bounce-back spot today with Zack Wheeler, who is back to his former elite self, having given up just one run in each of his last three starts. On the flip side, the Nats are starting a reliever who will probably server as an opener for Cade Cavalli, but they have the second-worse bullpen ERA in baseball this season. They have also nothing to play for, as they have been mathematically eliminated from the playoffs, so I like the Phillies to bounce back, win comfortably and cover the runline.
