Bracket (tournament)

A 16-player, single-elimination tournament bracket. The quarterfinals have been completed, and the semifinal games will be Lisa vs. Ernie, and Andrew vs. Robert. Then the finals will be a game between the two people who win in the semifinals. |
A
bracket is the diagrammatic representation of the series of games played during a
tournament, named as such because it appears to be a large number of interconnected (punctuational)
brackets.
There are several kinds of brackets, adapted to different types of tournaments. The most common are:
*
Single elimination brackets (
tennis,
basketball)
*
Double elimination brackets (
9-ball)
The "art" of filling in brackets, especially in
NCAA basketball, is referred to as
bracketology.
Brackets are most commonly found in profesional sporting leagues. Often, at the end of the regular season, the league holds a post-season tournament (most commonly called a playoff) to determine which team is the best out of all of the other teams in the league. This is done because often in professional sports there are at least two different conferences (like the American Football Conference and the National Football Conference in the NFL, the American League and the National League in Major League Baseball, and the Eastern Conference and the Western Conference in the NBA), and teams mostly play other teams in their own conference.
When there are only two different conferences, there are two sides of the bracket. One conference is on one side, while the other is on the opposite side. Teams that qualify for the post-season tournament only compete against teams in their own conference, until only one team from each conference remains. These two teams, called the conference champions, play each other to determine the best in the league. In other leagues, like the NHL, have two conferences but are divided into divisions, usually by region. In the post-season tournament, only the teams with the best records qualify, with the exception of the division leader having an automatic entry into the tournament.
Most professional post-season tournaments are single-elimination format. If a bye is required, the top seeded teams usually gets the bye. There is usually no third place match to separate the third and fourth place teams.
