Arizona Diamondbacks vs. San Francisco Giants Prediction

I’m on Arizona in both games. The Diamondbacks are just the better team fighting for something, and Arizona has frankly owned the Giants in this season series up to this point in the year. Both Kelly and Bratt are decent options here and I think Arizona gets it done here as well. Give me Arizona.
