Diamondbacks vs Nationals Prediction

The Nationals are 6-2 in their last 8 meetings against the Diamondbacks, having won their last two meetings in Washington.

In this Diamondbacks vs Nationals Prediction, the Diamondbacks are coming as -120 road favorites. Those two teams are the best hitting teams against lefties this season and I don’t trust either pitcher in this matchup. Eduardo Rodriguez has given up 9 runs across his last three starts and gave up 4 runs in his previous meeting against the Nationals this season, while Carson Palmquist is a reliever with terrible numbers and the Nationals have the third-worse bullpen in baseball. Both offenses have been scorching-hot, with the Dbacks having scored 35 runs and the Nationals 22 in their last three games respectively. Take the over 9.5 runs in this one.
