Diamondbacks vs Red Sox Prediction

The Dbacks are 6-3 in their last 9 meetings against the Red Sox but have lost their last two visits in Boston.

In this Diamondbacks vs Red Sox Prediction, the Red Sox are coming as -140 home favorites. Both pitchers have been scorching-hot coming into this matchup, as Pfaadt is coming off an insane four straight shutouts and has been even better on the road, while Tolle has given up two runs or less in six of his last seven games. Both teams have been in very good form offensively but those two pitchers are playing out of their minds and the Red Sox have the best bullpen in baseball, so I will go with the under 8 runs in this one.
