San Francisco Giants vs. Pittsburgh Pirates Prediction

I’m on the under here. The under got demolished early on Tuesday, but I think this is still two teams that have had issues against righties for much of August and into September, and two teams I don’t trust to be consistently producing double-digit runs game in and game out. I think with two solid options in their respective rotations in Roupp and Jones, I’m looking for the under to cash here. Give me the under.

Chris Ruffolo's Pick: Under 8.5
