Red Sox vs Mets Prediction 

New York comes into this contest desperately looking for a win, but their offense has really struggled in their last five games. The Mets are 12-14 on the road this year, while the Red Sox are 13-11 at home. Boston has won two of their last three games, and they are starting Buehler, who has allowed two earned runs or fewer in three of his last four starts but is coming off the IL. New York is going with Holmes, who has allowed one earned run or fewer in three of his last five starts. I like how Buehler has pitched this season, and with the Mets struggling at the plate, I will take the Red Sox to win.
