The 2026 Major League Baseball postseason opens on September 29, 2026, launching a 12-team tournament under the Collective Bargaining Agreement format established in 2022. Twelve clubs enter the bracket across the American and National Leagues, chasing a path from the Wild Card Series through to the World Series.
Format and Postseason Structure
Postseason qualification splits evenly between leagues, taking six teams from the American League and six from the National League. Each circuit features its three division champions alongside three wild card entries. Regular-season records determine seeding across the board.
The top two division winners in each league secure the No. 1 and No. 2 seeds, earning automatic byes directly into the Division Series. The third division champion receives the No. 3 seed and hosts the No. 6 seed in a best-of-three Wild Card Series. Meanwhile, the remaining wild card entries take the No. 4 and No. 5 seeds, squaring off in another best-of-three matchup hosted entirely by the higher-seeded club.
Winners advance to the best-of-five Division Series, followed by the best-of-seven League Championship Series to crown the American and National League pennant winners. The two champions ultimately meet in the best-of-seven World Series.
American League Field and Division Winners
The organization returns to October baseball for the sixth time in eight seasons, covering 2019 through 2023 and 2026.
In the AL Central, the Cleveland Guardians claimed the division crown at 85–76. Cleveland makes its third consecutive postseason appearance running from 2024 to 2026, marking its fifth trip to the playoffs in six years.
The New York Yankees finished with a 93–68 mark, earning the best record among non-division winners in the American League. The Yankees lock down their third straight postseason berth and their tenth appearance in the last 12 seasons.
The Boston Red Sox booked their ticket with an 87–74 record, grabbing the second-best wild card mark in the AL for their second consecutive postseason appearance. The Chicago White Sox rounded out the field with an 83–78 record, securing the third wild card spot. Their qualification joins 2008 and 2020 as just the third time in history that both Chicago franchises reached the postseason in the same year.
National League Standings and Historic Milestones
The Milwaukee Brewers set the pace in the Senior Circuit, finishing atop the NL Central at 102–59. The Brewers punch their ticket for the fourth consecutive year, reflecting eight playoff appearances in the last nine seasons.
Out west, the Los Angeles Dodgers claimed the NL West crown with a 99–62 record.
The Atlanta Braves countered by winning the NL East with a 94–67 record, earning their eighth postseason berth in nine seasons. Further down the bracket, the San Diego Padres posted a 90–71 record to grab the top NL wild card spot, setting a franchise record with three straight postseason appearances. The Chicago Cubs followed with an 88–73 mark as the second wild card team, returning to October baseball for the seventh time in 12 seasons and giving the Windy City its third dual-postseason showcase alongside the White Sox.
Remaining Qualification Battles
With most of the bracket settled, final wild card positioning and remaining series matchups hinge on the outcomes of the Houston Astros and Texas Rangers in the American League, alongside the Philadelphia Phillies and Arizona Diamondbacks in the National League.
