How Do the MLB Playoffs Work? (12-Team Format)
On this page5
The MLB playoffs are a 12-team bracket — six per league: the three division winners plus three wild cards. The top two division winners in each league get a bye to the Division Series; the other four play a best-of-three Wild Card Series. Winners advance through the Division Series and League Championship Series to the World Series. The field expanded to 12 in 2022.
Who qualifies
Six teams from each league reach the postseason: the three division winners, plus the three best remaining teams by record as wild cards.
| Seed | How you get in |
|---|---|
| 1–2 | Top division winners (earn a bye) |
| 3 | Third division winner |
| 4–6 | Three wild cards (best records left) |
The four rounds
- Wild Card Series — best-of-three, hosted entirely by the higher seed
- Division Series (ALDS/NLDS) — best-of-five
- League Championship Series (ALCS/NLCS) — best-of-seven
- World Series — best-of-seven
A champion wins three series to reach the World Series and a fourth to win it. Full seeding for the opening round is in our MLB wild card guide.
The bye and home field
The top two division winners per league skip the Wild Card Series — the main reward for a great regular season, though the layoff can cool a hot team. Home-field advantage otherwise goes to the higher seed, and in the World Series to the pennant winner with the better record.
No ties, ever
Baseball has no clock: a game runs into extra innings until someone leads at the end of an inning. Postseason games are played to a finish however long they take.
How it compares
MLB’s 12-team field is smaller than the 16 in the NHL playoffs, and it mixes best-of-three, five and seven series rather than all best-of-seven — plus the unique top-seed bye. For more on the sport, see our baseball guides.
Frequently asked questions
How many teams make the MLB playoffs?+
Twelve teams reach the MLB playoffs — six from the American League and six from the National League. In each league, the three division winners qualify automatically, and the three best remaining teams by record take the wild-card spots. This 12-team format has been in place since 2022, up from the previous 10-team system.
What are the rounds of the MLB playoffs?+
There are four rounds: the best-of-three Wild Card Series, the best-of-five Division Series (ALDS/NLDS), the best-of-seven League Championship Series (ALCS/NLCS), and the best-of-seven World Series. A team must win three series to reach the World Series and a fourth to win it, playing as many as 22 games across the postseason.
How does the MLB Wild Card Series work?+
The two lowest playoff seeds in each league — the third division winner and the two lower wild cards — meet the middle seeds in a best-of-three Wild Card Series, with all games hosted by the higher seed. The top two division winners in each league get a bye straight to the Division Series. See our guide to [how the MLB wild card works](/how-does-the-mlb-wild-card-work/) for the seeding detail.
Why do the top MLB seeds get a bye?+
The top two division winners in each league earn a first-round bye to reward their strong regular seasons, skipping the Wild Card Series and advancing straight to the Division Series. The bye is meant to give the best teams an edge, though some argue the extra days off can cool a team down. It is the main reward for finishing among the top two in a league.
How is home-field advantage decided in the MLB playoffs?+
Home-field advantage in each series generally goes to the higher seed, based on regular-season record. In the World Series, home field goes to the pennant winner with the better regular-season record, rather than to a league as it once did or being tied to the All-Star Game. Better regular-season performance is rewarded with hosting more games.
Do MLB playoff games ever end in a tie?+
No. Baseball has no clock and no ties — a game continues into extra innings until one team leads at the end of an inning. Playoff games in particular are played to a finish no matter how long they take, and some postseason classics have run well past nine innings. Every series is decided on the field, unlike the earlier tiebreaker games once used to settle regular-season deadlocks.
How does the MLB postseason compare to other leagues?+
MLB's 12-team field is smaller than the NBA's or NHL's 16, and its series are a mix of best-of-three, five and seven, unlike the [NHL playoffs](/how-do-nhl-playoffs-work/), where every round is best-of-seven. Baseball also uniquely rewards the top seeds with a bye. Each league shapes its bracket around how its sport is played and how long a series should be.
