Arizona Diamondbacks vs. Pittsburgh Pirates Prediction

I’m on the over in this one. These are two starting pitchers I don’t really trust, as Mitch Keller’s been getting cranked for much of the season and Kelly is up against it against this Pirates lineup that’s been smashing right-handed pitching for much of the season. I think this game ends up being high-scoring so I’ll roll with the over in this one.
