Guardians vs Red Sox Prediction

The Red Sox are 6-3 in their last 9 meetings against the Guardians but have lost their last two home meetings.

In this Guardians vs Red Sox Prediction, the Red Sox are coming as -130 home favorites. I love the pitching in this matchup, as both starters have a combined 6.49 ERA and a sub-1.20 WHIP. They are both in a rough stretch so they are both in a bounce-back spot and yesterday’s game had just 5 total runs. Both bullpens have been excellent and Boston is 9-1 to the under in its last 10 games and the Guardians have scored just four runs in their last two games. Take the under 7.5 in this one.
