MLB Postseason 2026: Complete Playoff Preview
Every autumn, Major League Baseball takes centre stage as teams chase the sport’s biggest prize through a postseason packed with high-pressure games, pitching battles and dramatic swings in momentum.
The 2026 MLB Postseason is now here, with all 12 playoff places decided. The Tampa Bay Rays, Cleveland Guardians, Houston Astros, New York Yankees, Boston Red Sox and Chicago White Sox represent the American League, while the Milwaukee Brewers, Los Angeles Dodgers, Atlanta Braves, San Diego Padres, Chicago Cubs and Philadelphia Phillies make up the National League field.
The opening Wild Card Series begin on Tuesday, 29 September, before the postseason progresses through the Division Series, League Championship Series and ultimately the World Series.
Here, we’ll explain how the playoff system works, when each round takes place, which teams are involved and what to watch as the 2026 postseason gets underway.
How Does The MLB Postseason Work?
The MLB postseason features 12 teams — six from the American League and six from the National League. Each league sends its three division winners and three Wild Card teams into the playoffs. The two division winners with the best records in each league receive a first-round bye and advance directly to the Division Series.
The remaining eight teams compete in the Wild Card Series. In each league, the No. 3 seed faces the No. 6 seed, while the No. 4 seed plays the No. 5 seed. Every Wild Card Series is best-of-three, with all three potential games played at the higher seed’s ballpark.
The winners advance to the Division Series, which are best-of-five. From there, the American League and National League winners meet in their respective Championship Series. Both the ALCS and NLCS are best-of-seven, as is the World Series.
The bracket is not reseeded after the Wild Card Series. The winner of the No. 3 versus No. 6 series goes on to face the No. 2 seed, while the winner of the No. 4 versus No. 5 series meets the No. 1 seed in the Division Series.
That structure makes the opening round particularly important. Teams without a first-round bye must win a short series before entering the longer Division Series, while the top two seeds get additional time to prepare their rotations and rest their players.
When Is The MLB Postseason 2026?
The 2026 MLB Postseason begins on Tuesday, 29 September, with all four Wild Card Series starting that day. Game 2 is scheduled for Wednesday, 30 September, with Game 3 on Thursday, 1 October if required.
The 2026 Wild Card match-ups are:
- Philadelphia Phillies at Atlanta Braves
- Chicago White Sox at Houston Astros
- Boston Red Sox at New York Yankees
- Chicago Cubs at San Diego Padres
The Division Series is scheduled for 3-10 October. The League Championship Series follows from 11-20 October, with the exact dates depending on the league and series progression.
The 2026 World Series is scheduled to begin on Friday, 23 October. Games 1 and 2 are scheduled for 23 and 24 October, followed by Game 3 on 26 October and Game 4 on 27 October. If necessary, Games 5, 6 and 7 are scheduled for 28, 30 and 31 October respectively.
How Many Teams Make It To The MLB Postseason?
Twelve teams make the MLB postseason under the format introduced in 2022. Each league contributes six teams: three division champions and three Wild Card teams.
The two division champions with the best records in each league receive byes into the Division Series. The third division winner and three Wild Card teams then compete in the best-of-three Wild Card Series.
For 2026, the first-round byes belong to the Tampa Bay Rays and Cleveland Guardians in the American League, and the Milwaukee Brewers and Los Angeles Dodgers in the National League. The remaining eight clubs begin their postseason campaigns in the Wild Card Series.
The expanded 12-team format gives more clubs an opportunity to reach October while also placing greater value on winning a division and securing one of the top two records within a league.
Which Teams Are In The MLB Postseason?
In the American League, the Tampa Bay Rays are the No. 1 seed after winning the AL East, while the Cleveland Guardians are the No. 2 seed after winning the AL Central. Both receive first-round byes. The Houston Astros, winners of the AL West, are the No. 3 seed and host the Chicago White Sox, the No. 6 Wild Card seed.
The New York Yankees are the No. 4 seed and host the No. 5 Boston Red Sox in the other American League Wild Card Series.
The National League field consists of the Milwaukee Brewers, Los Angeles Dodgers, Atlanta Braves, San Diego Padres, Chicago Cubs and Philadelphia Phillies. The Brewers are the No. 1 seed after winning the NL Central, with the Dodgers No. 2 after winning the NL West. Both receive byes.
The Braves, winners of the NL East, are the No. 3 seed and host the Phillies, while the No. 4 Padres host the No. 5 Cubs.
That gives the opening postseason bracket the following match-ups:
American League:
No. 3 Houston Astros vs No. 6 Chicago White Sox
No. 4 New York Yankees vs No. 5 Boston Red Sox
No. 1 Tampa Bay Rays — bye
No. 2 Cleveland Guardians — bye
National League:
No. 3 Atlanta Braves vs No. 6 Philadelphia Phillies
No. 4 San Diego Padres vs No. 5 Chicago Cubs
No. 1 Milwaukee Brewers — bye
No. 2 Los Angeles Dodgers — bye
The final field means several teams mentioned as possible contenders earlier in the season, including the Toronto Blue Jays, Minnesota Twins, Texas Rangers, St. Louis Cardinals and Arizona Diamondbacks, will not take part in the 2026 postseason.
How Many Games In The MLB Postseason?
The number of games a team plays depends on how far it advances and whether its series go the distance.
The Wild Card Series is best-of-three, meaning a team needs two wins to advance. The Division Series is best-of-five, requiring three wins, while the League Championship Series and World Series are both best-of-seven and require four victories.
A team that wins every series by the minimum number of games can therefore reach the World Series title after 11 games: two in the Wild Card Series, three in the Division Series, three in the League Championship Series and three in the World Series.
However, a team with a first-round bye can win the championship in as few as 11 games as well, because it skips the Wild Card Series and then needs three wins in the Division Series, four in the League Championship Series and four in the World Series.
At the other extreme, a team that has to play the Wild Card Series and goes the full distance in every round could play 22 postseason games. The difference places considerable importance on pitching depth, bullpen usage, defensive consistency and the ability to withstand a demanding schedule.
Who Won The World Series 2025?
The Los Angeles Dodgers won the 2025 World Series, defeating the Toronto Blue Jays 4-3 in a seven-game series. The Dodgers became the champions after winning Game 7 by a 5-4 score in Toronto.
The 2025 World Series was notable for its length and drama. The Dodgers recovered from losses in Games 1, 4 and 5 to force a decisive Game 7, where they eventually secured the championship.
Yoshinobu Yamamoto was named World Series MVP after a remarkable postseason performance. He delivered a complete game in Game 6 and then returned on zero days of rest to contribute again in Game 7.
The result gave the Dodgers consecutive World Series championships and provides an important backdrop to their 2026 campaign as they attempt to defend their title.
Who Are Favourites To Win The World Series 2026?
The Dodgers arrive as the defending World Series champions, while the Brewers, Rays and Guardians have earned first-round byes as the top two division winners in their respective leagues. The Yankees, Astros, Braves, Padres, Cubs, Phillies, Red Sox and White Sox must begin in the Wild Card Series.
If considering any form of betting, keep wagers modest and within a planned budget. Odds can move quickly during the postseason, particularly once starting pitchers, line-ups and series results become known.
