Phillies vs Red Sox Prediction

Both teams are tied 5-5 in their last 10 meetings but the Red Sox have won their last three meetings in Boston.

In this Phillies vs Red Sox Prediction, the Red Sox are coming as -130 home favorites. Boston lost yesterday but they have a big pitching advantage today, as the red-hot Sonny Gray, who has just one earned run in three of his last four starts, goes up against a struggling Andrew Painter, who has given up 16 runs across his last three starts. The Red Sox also have the 5th-best bullpen to come after Gray and are also in a bounce-back spot at home, so I expect them to get the job done in a good price.
