Arizona Diamondbacks vs. San Francisco Giants Prediction
I’m on the Diamondbacks in this one. Right now it’s just a case of two teams headed in different directions and while I think McDonald will be a decent piece for the Giants’ rotation, he’s coming off of his worst start of the year and this Diamondbacks team is too tough to step in front of right now. Give me the Diamondbacks in this one.
