San Francisco Giants vs. San Diego Padres Prediction

I’m on the under here. I think that until we see either one of these teams break through offensively, the under has to be the look. San Francisco’s offense has been anemic through their first three games, and the Padres were kind of in the same boat through the first three games of the year and I think this one ends up being low-scoring so give me the under here.

Chris Ruffolo's Pick: Under 8.5
