In this Guardians vs Royals Prediction, the Royals are coming as -125 home favorites. The Royals swept the Mariners in Seattle and are now back home with Wacha on the mound, who has given up 10 runs across his last two starts. On the flip side, Bibee has given up just three runs across his last three starts and the Guardians have both a better offense and a better bullpen, so I like them as road dogs in this spot. Take the Guardians on the road for plus money.
