How Many Teams Make the Playoffs in MLB?

By Sarah Miller · November 14, 2043

In Major League Baseball (MLB), 12 teams qualify for the playoffs each season: 6 from the American League and 6 from the National League. This expanded format, introduced in 2022, includes three division winners and three wild card teams from each league, enhancing postseason competition and fan engagement.

Understanding the MLB Playoff Structure

The current MLB playoff system is designed to balance competitive fairness with increased excitement. Since the 2022 season, the league has used a 12-team format, up from the previous 10-team structure. This change allows more teams to remain in contention deeper into the regular season, boosting viewership and stadium attendance.

How Teams Qualify for the Playoffs

Division Winners (3 per league): The team with the best record in each of the three divisions (East, Central, West) automatically qualifies.
Wild Card Teams (3 per league): The next three teams with the best records in each league, regardless of division, earn wild card spots.
Seeding: Division winners are seeded #1–#3 based on record; wild cards are #4–#6.

MLB Postseason Format and Tournament Flow

Once the 12 teams are set, the postseason unfolds in a four-round tournament:

Playoff Round Breakdown

Wild Card Series: Best-of-three series hosted by the higher seed. The #3 seed hosts #6, and #4 hosts #5 in each league.
Division Series (ALDS/NLDS): Best-of-five matchups between remaining teams.
Championship Series (ALCS/NLCS): Best-of-seven series to determine league champions.
World Series: The American League champion faces the National League champion in a best-of-seven series to crown the MLB champion.

Historical Evolution of the MLB Playoffs

The playoff format has evolved significantly since MLB's inception. Initially, only the two league champions met in the World Series. Over time, expansion and competitive balance concerns led to structural changes.

Key Changes Over the Years

1969: Introduced League Championship Series after adding divisions.
1994: Added the wild card and three-division format (delayed to 1995 due to strike).
2012: Expanded to include a second wild card team and added the Wild Card Game.
2020: Temporary 16-team format due to the pandemic-shortened season.
2022: Permanent shift to 12 teams with a best-of-three Wild Card Series.
