How MLB Territory Conquest Works

At the start of each season, every team owns the territory closest to their ballpark. Win a game, take ALL of your opponent's land. Lose, and everything you built disappears. Simple rules, brutal consequences.

Territory Rules

  • Each team owns the land closest to their ballpark
  • Win = take ALL of the loser's territory
  • Lose = lose everything
  • Territory accumulates all season - no resets until next year
