San Francisco Giants vs. St. Louis Cardinals Prediction
I’m on the Cardinals in this one. I’m still not sold on Blade Tidwell’s game and now with San Fran losing arguably their best bat for the year with Rafael Devers out, it makes it even harder to back this team. Andre Pallante is not my favorite Cardinals option on the mound but he’s been pretty solid this year all things considered and I look for the Cards to take it here. Give me St. Louis.
