San Francisco Giants vs. Washington Nationals Prediction

I’m on the over here. It’s cashed with ease in the first two games, and even in a lefty/lefty matchup here, I think we’re getting some runs as well. Both sides have hit lefties well this season, and these are two bullpens I’m still having some trust issues with. All in all, I think it ends up being a bit of a shootout here so give me the over.
