The 2017 MLB postseason bracket represented the culmination of a grueling six-month campaign, where 10 teams battled through 45 games to determine a World Series champion. This particular postseason is remembered for its dramatic narratives, from a small-market team defying expectations to a historic bullpen meltdown. Understanding the structure and key moments of this bracket provides insight into the modern era of baseball competition.
Postseason Format and Qualification
The 2017 bracket followed the established format introduced in 2012, featuring two wild-card teams from each league competing in a one-game playoff. The winners advanced to face the top seeds in the Division Series. The setup created high-leverage moments from the outset, as a single swing of the bat could eliminate a team that had won 90 or more games. This format amplified the intensity of games that would otherwise be considered routine.

The Astros dominated their division with a 101-win campaign, showcasing a lineup that would soon be considered historic. The Red Sox, despite a strong regular season, carried the weight of past disappointments into October.
National League Power Structure
In the National League, the Los Angeles Dodgers entered as the heavy favorites, having set a new franchise record with 104 wins. The Washington Nationals and Chicago Cubs completed the divisional spots, while the Arizona Diamondbacks and Colorado Rockies fought fiercely for the final two playoff berths.
