Diamondbacks vs Red Sox Prediction
The Dbacks are 6-2 in their last 8 meetings against the Red Sox and are 3-1 in their last 4 visits in Boston.
In this Diamondbacks vs Red Sox Prediction, the Red Sox are coming as -160 home favorites. I like the Red Sox at home in this one with Ranger Suarez on the mound, who has been the superior pitching option than Merrill Kelly and his 5.11 ERA, and a 1.48 WHIP. Kelly has given up 5+ runs in two of his last three starts and the Dbacks have been ineffective against lefties lately. On top of that, the Red Sox have the best bullpen ERA in baseball this season, so I expect them to get the job done at home in this one.
