Playoff Seeding: Teams are seeded by win-loss record, with division winners automatically seeded ahead of wild card teams regardless of record.

Standard Tiebreakers: If teams are tied in the standings at the end of the regular season and would compete in the same playoff round, standard MLB tiebreaker procedures apply (head-to-head record, divisional record, etc.).
Tiebreaker Game(s): If teams are tied and one team would receive a playoff bye while the other would not, OR if one team would make the playoffs while the other would be eliminated, a tiebreaker game must be played.
Multiple Team Ties: When three or more teams are tied, the number of tiebreaker games played equals the number of teams involved minus one. The format and schedule for multi-team tiebreakers will be determined by the Commissioner.

League Division Series (LDS) (20 and 24-team leagues only):
Best-of-5 series
Format: 2-2-1 (Games 1-2 at higher seed, Games 3-4 at lower seed, Game 5 at higher seed if necessary)
Higher seed receives home field advantage
League Championship Series (LCS):
Best-of-7 series
Format: 2-3-2 (Games 1-2 at higher seed, Games 3-5 at lower seed, Games 6-7 at higher seed if necessary)
Higher seed receives home field advantage
World Series (WS):
Best-of-7 series
Format: 2-3-2 (Games 1-2 at team with better record, Games 3-5 at other team, Games 6-7 at team with better record if necessary)
Home field advantage determined by regular season record, regardless of league seeding
Net Play Requirement: All playoff games must be played using net play. The block system used during the regular season does not apply to the playoffs.
Advance Scheduling: All playoff games are scheduled in advance by the Commissioner. Teams must coordinate with opponents to complete games according to the playoff schedule.

Roster Composition: Playoff rosters follow the same limits as the regular season:
26 active players maximum
Maximum of 13 pitchers
All players must be on the 40-man roster
Roster Changes Between Rounds: Teams may modify their active roster between playoff rounds (e.g., between LDS and LCS, or between LCS and World Series).
Injuries During Playoffs: The injury system continues to operate during the playoffs. Players may be injured between playoff rounds using the same usage-based formula described in Rule 6.4.
Injured List Moves: Teams may make Injured List moves during the playoffs following the same rules as the regular season (Rule 6.4).

Division Series and Championship Series: Home field advantage is awarded to the higher-seeded team based on playoff seeding.
World Series: Home field advantage is awarded to the team with the superior regular season record, regardless of playoff seeding or league affiliation.
Tied Records in World Series: If both World Series participants have identical regular season records, home field advantage is determined by head-to-head record during the regular season. If teams did not play each other or split the season series, a coin flip determines home field advantage.

Playoff Teams Draft Last: Teams that qualify for the playoffs draft after all non-playoff teams in the subsequent amateur draft (as detailed in Rule 3.4).
Playoff Draft Order: Among playoff teams, draft order is determined by reverse order of playoff finish:
World Series loser picks second-to-last
World Series winner picks last
All other playoff teams pick in reverse order of elimination

Playoff Revenue and Prizes: To be determined in consultation with team owners. This section will be updated once playoff revenue distribution and prize structures are finalized.
