St. Louis Cardinals vs. Kansas City Royals Prediction

I’m on the over in this one. Noah Cameron’s been solid but he got rocked in his last start and now faces a Cardinals team that’s been solid against lefties in the month of June. On the flipside, the Royals have also been solid against southpaws and Matthew Liberatore has been giving up his fair share of damage in recent starts. I’ll rock with the over here.
