U.S. — Major League Baseball has outlined the structure for its upcoming postseason, confirming that twelve teams will qualify for the playoffs with six from the American League and six from the National League. The league announced that the 2026 MLB postseason is tentatively scheduled to begin on Tuesday, Sept. 29, 2026.

The playoff format consists of four rounds: Wild Card Series, Division Series, League Championship Series, and World Series. Under the current seeding rules, the top two division winners in each league receive a bye to the Division Series, bypassing the opening round entirely.

Teams are not reseeded after the Wild Card Series; the bracket remains fixed throughout the remainder of the playoffs. The Division Series is a best-of-five format using a 2-2-1 home-field arrangement. The League Championship Series and World Series are best-of-seven formats using a 2-3-2 home-field arrangement.

MLB playoff seeding assigns the No. 1 seed to the division winner with the best record in the league, the No. 2 seed to the division winner with the second-best record, and the No. 3 seed to the division winner with the third-best record. The No. 4 seed goes to the Wild Card team with the best record, the No. 5 seed to the Wild Card team with the second-best record, and the No. 6 seed to the Wild Card team with the third-best record. A Wild Card team can finish with a better regular-season record than a division winner and still receive a lower seed.

The 2026 World Series is scheduled to open on Friday, Oct. 23, 2026, on FOX. If extended to a Game 7, the series is scheduled to conclude on October 31, 2026, as per the official 2026 postseason schedule announced by MLB. National League Division Series, National League Championship Series, and World Series games carried on FOX and FS1 can be streamed via FOX One.

The league champion with the better regular-season record receives home-field advantage in the World Series, regardless of postseason seed. If World Series participants finish with identical regular-season records, MLB applies its tiebreaker system to determine home-field advantage. MLB eliminates Game 163 tiebreakers for division titles or playoff spots, settling ties mathematically beginning with head-to-head record. If a tie remains after head-to-head record, MLB uses additional criteria including intradivision and interdivision records.

Postseason extra innings do not use the automatic runner at second base. Managers begin postseason games with two replay challenges instead of one.

Why It Matters

The Wild Card was first introduced in 1995 following the 1994 strike, which canceled the postseason and led to the creation of the Wild Card as the winningest non-division winner team. The Wild Card Series became a permanent best-of-three playoff format starting in the 2022 season, having been instituted as a single wild card game in a prior season and used as a best-of-three series in 2020 as a one-off. The World Series was first played to determine the championship team of baseball after the American League declared itself the second major-league circuit in the United States.

Further context notes that the National League Division Series is a Major League Baseball series to determine which two teams from the National League will advance to the National League Championship Series. In a prior season, the postseason included an extra round of series due to a midseason strike, but no Wild Card teams were involved, as the format prior to 1995 did not include a Wild Card. The 2020 World Series was held entirely at a neutral site (Globe Life Field in Arlington, Texas) due to the COVID-19 pandemic, marking the first and only time in MLB history that the World Series was not hosted by a participating team's home stadium.
