Houston Astros vs. San Francisco Giants Prediction
I’m backing the Astros in this one. It’ll be interesting to see who the Giants end up sending out in this game, but the Giants and consistent victories/success isn’t something we’ve been able to count on with this team over the years. I think this ends up being an Astros bounce back W as Houston’s just been the much better team this season so give me the ‘Stros in this one.
