Arizona Diamondbacks vs. Kansas City Royals Prediction

I’m on the Royals in this one. Noah Cameron has been on another level in the month of August, and I think it carries over into September as he builds solid vibes going into 2027. Arizona’s got more to fight for at this point, but the Royals have one of their best going and I think the Royals take care of business here. Give me KC.
