St. Louis Cardinals vs. Kansas City Royals Prediction

In my view, the way to go in this contest is the total rather a side. Why? St. Louis starting pitcher Dustin May has pitched at a high level recently, allowing no earned runs in his last two starts made this season, while St. Louis hurler Stephen Kolek has amassed a rather impressive 2.68 ERA in eight starts made this season. With that said, I see a game where the starting pitchers minimize offensive production. I am backing under 9.5 runs in this game.
