How MLB Territory Conquest Works

  • Every team starts with the land closest to its ballpark.
  • Win a game and you take all of the loser's territory.
  • Territory carries over all season, with no resets until next year.
  • Click any territory to trace every team that held it.

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)
