A practical guide to the KBO playoff bracket, including why fourth place has a major Wild Card advantage, where each game is hosted, and what happens after ties or weather interruptions.
Key Takeaways
- Fourth place advances from the Wild Card with one win or one draw; fifth place must win both road games.
- The Semi-Playoff and Playoff are best-of-five series, while the Korean Series is best-of-seven.
- The Korean Series uses a 2-3-2 home format, with the regular-season champion hosting Games 1, 2, 6 and 7.
- Postseason games can last 15 innings before being declared draws.
- Weather-interrupted postseason games are suspended and resumed rather than declared no-games or rain-shortened final results.
The KBO postseason rewards every step up the regular-season standings. The fifth-place club begins in the Wild Card round, while the regular-season champion advances directly to the Korean Series. Between those points are two best-of-five rounds that progressively introduce the third- and second-place teams.
Current-rule note: The format below reflects KBO’s current format pages and the structural rules in the latest fully published postseason operations notice available in the supplied materials, which covers 2025. As of October 6, 2026, KBO had not yet issued the full year-specific 2026 postseason notice located for this guide. Readers following a particular season should check the linked official KBO notices for late operational changes.
KBO postseason bracket at a glance
- Wild Card: Fourth place plays fifth place in a round lasting no more than two games.
- Semi-Playoff: The Wild Card winner faces the regular-season third-place team in a best-of-five series.
- Playoff: The Semi-Playoff winner faces the regular-season second-place team in a best-of-five series.
- Korean Series: The Playoff winner faces the regular-season champion in a best-of-seven championship series.
The Semi-Playoff and Playoff go to the first team to earn three wins. The Korean Series goes to the first team to earn four wins.
How the KBO Wild Card advantage works
The Wild Card round is not a conventional best-of-three or two-game aggregate series. Both games, if the second is needed, are played at the fourth-place club’s home park.
The fourth-place club advances after recording one win or one draw. The fifth-place club must win both games to move on.
This is sometimes described in English as a “one-win advantage,” but that shorthand can cause confusion. It does not need to be understood as a win already added to a series table. Operationally, the rule is simpler:
- If fourth place wins Game 1, fourth place advances.
- If Game 1 ends in a draw, fourth place advances.
- If fifth place wins Game 1, a second game is played.
- Fifth place advances only by winning both games.
The format gives fourth place two substantial benefits: every Wild Card game is at home, and one win or draw is enough to survive.
Semi-Playoff format and home-field order
The Wild Card winner advances to a best-of-five Semi-Playoff against the regular-season third-place club. The first team to three wins moves into the Playoff.
- Games 1 and 2: Hosted by the third-place team.
- Games 3 and 4: Hosted by the Wild Card winner.
- Game 5: Hosted by the third-place team.
Games 4 and 5 are played only if the series remains undecided. This creates a 2-2-1 home arrangement, with the higher-seeded third-place team holding the potential deciding game at home.
Playoff format and home-field order
The Semi-Playoff winner then faces the regular-season second-place club in another best-of-five series. As in the previous round, three wins are required to advance.
- Games 1 and 2: Hosted by the second-place team.
- Games 3 and 4: Hosted by the Semi-Playoff winner.
- Game 5: Hosted by the second-place team.
This round also follows a 2-2-1 home pattern. The winner earns a place in the Korean Series.
Korean Series format and home-field order
The regular-season champion enters the postseason at the Korean Series, where it faces the Playoff winner in a best-of-seven series. The first club to four wins becomes champion.
- Games 1 and 2: Hosted by the regular-season champion.
- Games 3, 4 and 5: Hosted by the Playoff winner.
- Games 6 and 7: Hosted by the regular-season champion.
The current Korean Series arrangement is therefore 2-3-2. KBO introduced this allocation from the 2025 season, replacing the previous 2-2-3 arrangement. Games 5, 6 and 7 take place only when needed.
What happens when a postseason game is tied?
KBO postseason games can continue through a maximum of 15 innings. If the score remains level after that point, the game is recorded as a draw.
The Wild Card has a special consequence: a draw immediately sends the fourth-place team into the Semi-Playoff because fourth place needs only one win or one draw.
In the other rounds, a tied game does not provide either team with one of the wins needed to take the series. Under the latest fully published operations notice in the supplied materials, an additional game is effectively placed after the series’ originally scheduled final game if it is still required to determine a winner.
Regular-season standings ties are different
A tie in the regular-season standings should not be confused with a drawn postseason game. KBO has separate procedures for determining postseason positions. For the 2026 regular-season makeup schedule, KBO stated that when exactly two clubs are tied for first place or exactly two are tied for fifth place, they play a separate tiebreaker game. Because the full 2026 postseason operations notice was not yet available in the supplied materials, fans should consult the current official notice before relying on year-specific tiebreaker details.
What happens when rain interrupts a postseason game?
Under the rules effective from 2025, KBO postseason games are not handled through no-game declarations or rain-shortened final results. An interrupted postseason game is instead suspended and resumed from the point at which play stopped.
When a suspended game is completed, it is the only game played that day. The game that had previously been scheduled for that date moves to the following day. This avoids completing one interrupted game and then beginning another postseason game on the same day.
The most recently published full operations notice in the supplied materials also provides for at least one travel day between postseason series. Separately, KBO’s October 6, 2026 regular-season schedule notice stated that a Wild Card participant must receive at least one travel day between its final regular-season game and the Wild Card opener. That notice was a scheduling update rather than the complete 2026 postseason rule announcement.
What this means for each seed
- First place: Goes directly to the Korean Series and hosts Games 1, 2, 6 and 7.
- Second place: Enters in the Playoff and can reach the Korean Series with three wins.
- Third place: Enters in the Semi-Playoff and hosts the opening two games plus a possible Game 5.
- Fourth place: Hosts the entire Wild Card round and advances with one win or one draw.
- Fifth place: Must win two consecutive road games in the Wild Card round before entering the best-of-five bracket.
The central principle is straightforward: a higher regular-season finish means a later postseason entry point, more favorable hosting rights, or both. The largest single-round advantage belongs to fourth place in the Wild Card, but the regular-season champion receives the most valuable structural reward by avoiding every preliminary round.
