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

Shared Venues Note

Some teams in this season share a venue location. For visualization purposes, each team's territory boundary is calculated from a slightly offset position (~300 feet apart) to create distinct territories.

  • Sportsman's Park:
    • St. Louis Browns (nudged NE)
    • St. Louis Cardinals (nudged SW)
  • Connie Mack Stadium:
    • Philadelphia Athletics (nudged NE)
    • Philadelphia Phillies (nudged SW)
