In this Diamondbacks vs Red Sox Prediction, the Red Sox are coming as -145 home favorites. I like the Red Sox in this one, despite the fact that they will go for a bullpen game, as they have the best bullpen ERA in baseball this season. On the flip side, Mitch Bratt has been bad on the road for the Dbacks with a 5.62 road ERA and the Red Sox have been better against lefties. Take the Red Sox to win this one at home.
