San Diego Padres vs. San Francisco Giants Prediction

I’m on the over here. These are two starting pitching options in Waldron and Houser that have been very hittable early on this season and two offenses that I think can do damage early and often against these two starters. The bullpens have been solid but we saw plenty of runs on Tuesday and I think there’s some left over for this game as well. Give me the over.
