How to read this:
Combined score = park factor × (1 + weather_modifier/10). Games at the top are in the most
HR-friendly environments. Great for same-game parlays — stack multiple batters from the same
high-scoring game. Park factor comes from 2025–26 Statcast data; weather modifier incorporates
temperature, wind speed, and wind direction relative to home plate.
