Royals vs Red Sox Prediction 

Boston continues to be one of the hottest teams in the MLB and they have scored at least six runs in four straight games. The Red Sox are 39-21 at home this year, while the Royals are 28-30 on the road. Kansas City has allowed 18 runs in their last three games, but they are starting Wacha, who has allowed one earned run in each of his last four starts. The Red Sox are going with May, who has allowed at least four earned runs in three of his last five outings, but is making his first start since being traded from the Dodgers. I really like how Wacha is pitching right now and I think he will give the Royals a chance to win. Take KC here.
