Red Sox vs Rays Prediction
Boston was able to get the low scoring win on Friday night to even this series and they have won four of their last five games. The Red Sox are 7-11 at home this year, while the Rays are 11-9 on the road. Tampa Bay had their winning streak snapped last night, but they have allowed three runs or fewer in four of their last five. The Rays are starting Martinez, who has allowed two earned runs or fewer in five straight starts, while Tolle has allowed four earned runs over 17.2 innings. This is a great pitching matchup, but I can’t fade Martinez right now. Take the Rays here.
