MLB Playoff Format and Rules

The MLB format includes 12 teams, featuring the top 6 teams in each league. The top 3 seeds are reserved for the division winners ranked on winning percentage. The final three seeds in each league are decided by the 3 wildcard teams, or the 3 teams in their respective league with the highest winning percentage that did not win their division.

Tiebreakers

1. The team with the better head-to-head winning percentage during the regular season.
2. The team with the best overall record in intradivision games.
3. The team with the best overall record in intraleague games.
4. The team with the best record in the final 81 intraleague games of the season.
5. The team with the best record in the final 82 intraleague games of the season (provided the game added is not between the tied teams), continue one game back until the tie is broken (Interleague games are skipped and ignored in this process.)
6. Coin toss or drawing of lots will be used if all the above fail.
