How Park Factors Work

Park factors represent the percentage adjustment each ballpark applies to a given stat relative to a neutral venue. A +5% K factor means pitchers throw ~5% more strikeouts at that park, while a -8% K factor (Coors Field) means significantly fewer Ks.

These factors are baked into every FullCountProps projection. Our model adjusts pitcher K/9, batter TB/PA, and HR rates using these park-specific multipliers before running Monte Carlo simulations.

Weather conditions (temperature, wind speed/direction, humidity) create additional daily adjustments on top of the baseline park factors. Hot weather and wind blowing out boost offense; cold temps and wind blowing in suppress it.
