The 2025 Major League Baseball postseason ran from September 30 to November 2, 2025, featuring a 12-team bracket where the Los Angeles Dodgers ultimately defeated the Toronto Blue Jays in the World Series. With that victory, the Dodgers repeated as champions, securing their ninth title and becoming only the eighth franchise in MLB history to win back-to-back championships. The tournament was exceptionally competitive, as only two sweeps occurred across the entire bracket, with both Division Series, the ALCS, and the World Series all going to winner-take-all elimination games, and three of the four Wild Card Series needing a decisive Game 3. The field notably excluded the Houston Astros (for the first time since 2016) and the Atlanta Braves (for the first time since 2017), ending their long postseason streaks. Several teams achieved significant milestones, including the Seattle Mariners winning their first division title since 2001, the Dodgers tying the Yankees' record with a 13th straight postseason appearance, and the Chicago Cubs and Cincinnati Reds returning to the playoffs for the first time since 2020. The American League saw the Blue Jays, Mariners, and Guardians claim division titles, while the National League featured the Brewers, Phillies, and Dodgers at the top, setting the stage for a dramatic October.
