San Francisco Giants vs. Pittsburgh Pirates Prediction

I’m on the under in this one. It might be a bit of a square under and the obvious play when you look at the pitching matchup but these are two teams that have had issues against right-handed pitching in the last couple of weeks, and both teams have their respective aces starting in this game. I think this ends up being a low-scoring duel, so give me the under here.

Chris Ruffolo's Pick: Under 7.5
