Nationals vs Diamondbacks Prediction

The Nationals have won their last three meetings against the Dbacks, but the Dbacks have won their previous five meetings before that. The Dbacks are 3-1 in their last 4 meetings in Arizona, and over is 6-1 in their last 7 meetings.

In this Nationals vs Diamondbacks Prediction, the Diamondbacks are coming as -200 home favorites. Both teams have identical records, and home/away splits, so this line clearly overvalues the Dbacks, who have been on a free fall lately, with just one win in their last 9 games. The line screams take the Nationals, but I would rather not mess with those two volatile pitchers.

Pfaadt has an expected ERA of 6.39, and Soroka has been terrible this season. Both bullpens are bottom-4 in the league, with a combined 11.51 ERA, and both teams are better against righties, averaging 10 runs combined against right-handed pitching. Yesterday’s game had 16 total runs and I expect another high-scoring affair today. Take the over 9 in this one.
