Home-field advantage in the playoffs is one of baseball’s most coveted prizes: more games in your stadium, sleeping in your own bed, and the roar of your crowd behind you. In Major League Baseball, this advantage goes to the team with the best regular-season win-loss record, regardless of division or wild-card status.
The current system: best record earns it all
Since 2022, MLB restructured its playoff format to reward regular-season excellence. The team with the best record in the entire American League and the best in the entire National League automatically earn the #1 seed and home-field advantage throughout the postseason, including the World Series. For instance, the 2023 Houston Astros (104-58) and Atlanta Braves (104-58) were the top seeds in their respective leagues and opened every series at home.
Other qualified teams—wild cards and division winners—are ranked by record. If a wild card has a better record than a division winner, that wild card gets home field in its divisional series matchup.
What changed in 2022?
Before 2022, World Series home-field advantage alternated between leagues year to year, regardless of records. Now the team with the best regular season gets to play at home in every series, including the World Series. This rewards winning games in September and October, not just making the playoffs.
How wild-card seeding works
After the three division winners from each league are set, the next six teams with the best records become wild cards. These six are ranked strictly by total wins. The #1 wild card faces the division winner with the worst record in the Divisional Series.
| Seed | Criteria | Home Field? |
|---|---|---|
| #1 Seed (best league record) | Regular-season wins | Yes, all series |
| Division Winners (2-3) | Regular-season wins | Yes, if better record than opponent |
| Wild Cards (1-6) | Wins among wild cards | Yes, if better record than division winner |
What happens in a tiebreaker?
If two teams finish with identical records, head-to-head results (games directly between them) break the tie. If still tied, run differential (runs scored minus runs allowed) is used. This rarely occurs in the modern era, but it mattered in 2011 when the Braves and Phillies both finished 81-81.
Real impact: how much does home field matter?
Analytics suggest home-field advantage adds 3-5% win probability in a playoff series. In 2023, the Astros won 104 games and earned the top seed; the Braves matched that record in the other league and also secured their advantage. Both reached their respective League Championship Series.
FAQ
Can a team lose home-field advantage in the playoffs?
No. Once assigned based on regular-season record, it cannot be forfeited. If the #1 seed loses its divisional series, the next-best team takes its place in the next round.
Does the World Series always favor the best regular-season team?
Yes, since 2022. The team with the best record across both leagues plays its first four games at home (games 1, 2, 6, and 7 if necessary).
How was it before 2022?
World Series home field alternated between leagues each year, regardless of records. This changed to better reward regular-season performance and consistency.
