How Does the MLB Wild Card Work?
On this page5
In MLB, the wild card gives each league three playoff berths to the best teams that did not win their division. Since 2022 there are three wild cards per league — seeds 4, 5 and 6 — who play a best-of-three Wild Card Series against the lower division winners, while the top two division winners get a bye. It keeps strong teams in tough divisions alive.
How the wild card works
The three best non-division-winners in each league make the playoffs as wild cards. Combined with the three division winners, that fills each league’s six-team field. The wild card exists so a very good team stuck behind an even better one in its division still gets a postseason shot.
The Wild Card Series
| Matchup | Host |
|---|---|
| Seed 3 vs Seed 6 | Seed 3 (all 3 games) |
| Seed 4 vs Seed 5 | Seed 4 (all 3 games) |
It is best-of-three, entirely at the higher seed’s park. Seeds 1 and 2 — the top division winners — skip it with a bye. The full bracket is in our MLB playoffs guide.
Why it expanded to three
MLB added a third wild card per league in 2022 to keep more teams in the race, add an extra opening round of drama and revenue, and reduce how often a great team missed October just for its division. It grew the field from 10 teams to 12.
Wild cards can win it all
A wild card is often a strong club in disguise, so entering as a lower seed doesn’t stop a title run — several wild-card teams have won the World Series. That upside is a big reason the format is popular.
Not unique to baseball
The wild-card idea appears across sports; the mechanics differ by league. Our general wild card in sports explainer covers football, baseball and hockey. For more baseball, see our baseball guides.
Frequently asked questions
How many wild card teams are in MLB?+
Three per league since 2022, for six wild cards in total. They are the three teams in each league with the best records that did not finish first in their division. Adding a third wild card expanded the playoff field from 10 teams to 12 and created the current best-of-three Wild Card Series as a new opening round.
How does the MLB Wild Card Series work?+
The Wild Card Series is a best-of-three round. In each league, the third division winner (seed 3) hosts the lowest wild card (seed 6), while the top wild card (seed 4) hosts the middle wild card (seed 5). All three games are played at the higher seed's ballpark, giving them a real home-field edge. The winners advance to the Division Series.
Which teams get a bye past the wild card round?+
The two division winners with the best records in each league — seeds 1 and 2 — receive a bye directly to the Division Series and skip the Wild Card Series entirely. That bye is the reward for the strongest regular seasons. The third division winner does not get a bye and must play in the Wild Card Series despite winning its division. See [how the MLB playoffs work](/how-do-the-mlb-playoffs-work/) for the full bracket.
Can a wild card team win the World Series?+
Yes, and it has happened several times. Because a wild card team is often a strong club that simply played in a tough division, entering as a lower seed does not prevent a deep run. Multiple wild-card teams have gone all the way to win the World Series, which is part of why the format is popular — it keeps more good teams in contention.
Why did MLB add a third wild card?+
MLB expanded to three wild cards per league in 2022 to add postseason drama, keep more teams in playoff races deeper into the season, and create the extra revenue and TV inventory of a new opening round. It also reduced how often a great team could miss the playoffs entirely just for being in the same division as an even better one.
Is the MLB wild card the same as in other sports?+
The idea is the same — a playoff berth for a strong team that did not win its division or conference — but the details differ by league. In the NFL, for example, wild cards feed directly into a single-elimination bracket. Our general explainer on the [wild card in sports](/wildcard-in-sports/) covers how the concept works across football, baseball and hockey.
Does the wild card team ever host a series?+
In the Wild Card Series, the higher-seeded wild card can host if it faces a lower seed, but the round is structured so the better regular-season record hosts all three games. Beyond that opening round, home-field advantage in each series goes to the higher seed, so a low-seeded wild card usually plays on the road until it climbs the bracket.
