Arizona Diamondbacks vs. San Francisco Giants Prediction

I’m on the Diamondbacks here. The Giants have hit left-handed pitching well, but I still don’t trust this team whatsoever in terms of offensive production and if you need an example, look at Monday. They had solid numbers across the board and still got beat up by the Diamondbacks. I think Arizona’s on a roll and they’re not a team I’m looking to step in front of right now. Give me Arizona.
