Major League Baseball’s postseason uses a 12-team field: six teams from the American League and six from the National League. The format rewards the top two division winners in each league with a first-round bye.
At a glance
- Each league sends three division winners and three Wild Card teams.
- Seeds No. 1 and No. 2 receive byes into the Division Series.
- The Wild Card Series is best-of-three, hosted by the higher seed.
How the six seeds are assigned
Within each league, the three division winners receive the top three seeds. The remaining three postseason clubs are the Wild Card teams, seeded fourth through sixth by record and applicable tiebreakers.
The two division winners with the best records are seeds No. 1 and No. 2, and they advance directly to the Division Series. The third division winner is seeded No. 3 and plays in the Wild Card round.
The Wild Card matchups
Seed No. 3 hosts seed No. 6, while seed No. 4 hosts seed No. 5. Each series is best-of-three, and all games are scheduled at the higher seed’s park. The winner of the 3-vs.-6 series moves into a Division Series against the No. 2 seed. The 4-vs.-5 winner advances to face the No. 1 seed.
The later rounds
The Division Series is best-of-five. The League Championship Series and World Series are best-of-seven. Home-field priority in those rounds follows MLB’s published postseason rules rather than a new reseeding after every round.
What happens when records are tied
MLB no longer relies on an extra regular-season tiebreaker game. Instead, it uses a sequence of mathematical tiebreakers, beginning with head-to-head results and moving to intradivision and intraleague records when needed. Fans should check MLB’s current standings and official bracket because seed placement can change until the regular season is complete.
