San Francisco Giants vs. San Diego Padres Prediction

I’m on the Padres here. Mahle has not been a good pitcher to back on the road this season and San Diego has been playing some pretty solid baseball over the last week or so. I think this is a spot for San Diego to build on their strong showing from Friday’s win and to add to San Francisco’s misery once again here. Give me San Diego.
