San Francisco Giants vs. Kansas City Royals Prediction

I’m on the Royals in this game. I just think that Avila is the better starter here and he’s been far better at home this season. San Francisco continues to be hit or miss and Mahle hasn’t been very good on the road this season. I’ll back KC to get another W at home here.
