Houston Astros vs San Francisco Giants Prediction

Not a fan of openers, and King has been hit hard lately, but the Astros are simply the better team, and we’re getting a reasonable price. The Giants have had issues all year stringing wins together, and home-field advantage hasn’t mattered much for this group. The Astros are fighting for a division title, and games like this are gifts to closing that gap. Can’t afford to blow these opportunities. Give me the Astros and the reasonable price.
