Top Astros vs. Guardians predictions
After 10,000 simulations of Guardians vs. Astros, the model is going Over 7.5 combined runs. For over-under betting, no team has hit the Over more than Houston this year, with it sporting a 16-7 record (69.6%). Houston went 0-3 outright in its most recent series versus St. Louis, but the Over went 3-0 over the set.
