How It Works
A concise guide to how Baseball Sim turns historical data into pitch-by-pitch games, representative rosters, era-spanning matchups, and app-generated records.
Pitch-by-pitch simulation
Baseball Sim models games as a sequence of pitches, not as a shortcut from batter to final stat line.
