How It Works

The MLB postseason format determines the league champion through a multi-round playoff system involving ten qualifying teams—five from each league. The structure rewards regular-season performance while allowing wild card teams to make deep runs.

• Wild Card Games:Two single-elimination games held in each league, with the two lowest-seeded division winners hosting the two wild card teams.
• Division Series:Best-of-five series where the three division winners and the Wild Card winner compete, with home-field advantage going to the higher seed.
• League Championship Series:Best-of-seven format to determine the American and National League champions, with home-field advantage based on regular-season record.
• World Series:Best-of-seven matchup between the AL and NL champions, traditionally played in a 2-3-2 home-field format.
• Home-field advantage:Given to the team with the better regular-season record, a rule implemented in 2017 after the All-Star Game no longer decided it.
• Wild card teams:Two per league qualify based on the best records among non-division winners, adding unpredictability to the playoff picture.
