Kansas City Royals vs. St. Louis Cardinals Prediction

I’m on the Cardinals in this one. I just think that St. Louis is the better team in this matchup and Noah Cameron continues to have issues. I’m not the biggest fan of the Cardinals against a lefty, but I think St. Louis is good enough here to be able to get the job done and back Leahy up for the win here. Give me the Cardinals.
