Terminology


Synonyms

In many cases, organizations that function as leagues are described using a different term, such as association, conference, division, leaderboard, or series. This is especially common in individual sports, although the term "league" is sometimes used in amateur individual sports such as

Leagues and league systems

"League" and its synonyms may be used to encompass either a single competition or a related group of competitions. Many groups use
promotion and relegation In sports leagues, promotion and relegation is a process where teams are transferred between multiple divisions based on their performance for the completed season. Leagues that use promotion and relegation systems are often called open leagues ...
, where the best-ranked team(s) in the ''lower division'' are ''promoted'' to the ''higher division'' for the next season, and the worst-ranked team(s) in the ''higher division'' are ''relegated'' to the ''lower division'' for the next season. Under this system, "league" may refer both to a league system, a group of leagues that are tied together in a hierarchical fashion by promotion and relegation, and to the individual leagues within the league system. For example, in English association football, the

An alternate system of league organization which is used primarily in Australia, Canada, and the United States is a closed model which always has the same teams playing, with occasional admission of expansion teams and relocation of existing teams. There is no team movement between the higher ''major league'' and the lower '' minor leagues''. In many of these closed-model leagues in Canada and the United States, they are divided into subdivisions on historical or geographical lines. These may be referred to as ''conferences'' or ''divisions''. For example, the

The National League predates the American by 25 years and was considered a "major" league in comparison to its early competitors, and in a sense it simply extended this recognition to the AL, the only league of similar financial clout. In addition, the leagues played no interlocking schedule of any kind until 1995, and then added only a small amount of interleague play, with the main AL-NL competition occurring between their champions in the

Each of the major leagues also has its own set of awards to recognize the separation between the two, which means there are two MVPs, two Cy Young Award winners, etc. Since its name is constructed differently—a description of the status of two leagues rather than the title of one—it is common to hear "MLB" without "the" attached to it, as in "the most home runs in MLB this year", since one would not say "the Major League Baseball".


League organization

The common thread between all sports leagues is a structure that allows teams or individuals to compete against each other in a nonrandom order on a set schedule, usually called a ''season'', with the results of the individual competitions being used to name an overall champion. A league championship may be contested in a number of ways. Each team may play every other team a certain number of times in a round-robin tournament. Usually, teams play equal number of games or matches at their own stadium and at other teams', because home advantage is a major factor in many sports. When teams competing for a tournament championship do not play the same teams the same number of times, it is known as an unbalanced schedule. In such a set-up, the team with the best record becomes champion, based on either a strict win–loss–tie system or on a points system where a certain number of points are awarded for a win, loss, or tie, while bonus points might also be added for teams meeting various criteria. Many leagues also use
playoffs The playoffs, play-offs, postseason or finals of a sports league are a competition played after the regular season by the top competitors to determine the league champion or a similar accolade. Depending on the league, the playoffs may be eit ...
, where after teams compete in a regular season in a league format, the top teams (possibly determined by conference or division) advance to the playoffs. In some such leagues having the best regular season record is relatively unimportant, though top-seeded teams in some leagues, such as the NFL, can gain byes to later rounds of the playoffs, and teams finishing with the best records usually have the advantage of playing the weakest teams that have advanced to the playoffs.


Alternatives to traditional league organization

While round-robin and modified round-robin competitions are the most common form of league organization, there are a number of ways to organize a sporting competition, almost all of which may be described as a "league". Many sports organizations fall on a continuum between a total lack of organization, as in a pick-up game, and a formal league such as is common at the highest level of professional team sports.


Non-league sports

The simplest form of competition is to allow teams to play each other whenever they see fit. In some sports, such as horse racing, the main goal of the entrants is to win individual purses, and there is little or no ranking or competition outside winning certain major races. A small amount of league organization may be imposed on these non-league sports by way of a series or tournament tying several individual events together, such as the Triple Crown. Even in team sports that normally use a traditional league format, some teams often exist outside any league; these teams are generally known as barnstorming teams and either schedule games against local professional or amateur competition or bring their own competition, such as the barnstorming Harlem Globetrotters did when they toured with the Washington Generals. As with the Globetrotters, barnstorming teams sometimes emphasize spectacle over athletic competition. In Europe, the term "cup competition" is used to describe single elimination or

Rankings and leaderboards

Individual sports often use an alternative type of league organization where competitors are ranked against each other. In the simplest cases, such as
boxing Boxing (also known as "Western boxing" or "pugilism") is a combat sport in which two people, usually wearing protective gloves and other protective equipment such as hand wraps and mouthguards, throw punches at each other for a predetermined ...

ing tournaments. In some sports, points are assigned to results at individual competitions, and the resulting points are used to generate a season rankings and determine the season champion. While not usually referred to as "leagues", but "tours" or "series", these season-long competitions with set events are very similar to league structures in team sports. Examples of this are motorsport,

are traditionally organized into groups of teams known as ''conferences''. These conferences ordinarily keep league tables and crown champions within the conference, as other sports leagues do, but the individual schools also schedule a certain number of "non-conference" games that are organized independently between two schools in different conferences, or between a conference team and a non-conference team. Also, national championships in some college sports are determined by a ranking or playoff system that is independent of the individual conferences.


Round-robin sports leagues

Most major team sports play some form of round-robin schedule, where the goal is for each team to play a relatively balanced schedule with each other team in the league or in its league subdivision. Within this structure, there are a few significant differences between leagues, a few of which are set forth below.


Single-table versus unbalanced schedule

The simplest way to organize a sports league, and still one of the most common, is in a double round-robin format where each team plays each other team twice, once at home and once away. This ensures that every team plays an equally difficult schedule and that no team has undue home field advantage. This organization is still used in many team sports around the world. One potential drawback of this simple double round-robin format is that the number of teams in the league determines the schedule. Larger leagues may not be able to play as many games as such a system would require, and smaller leagues may want more games. In addition, leagues whose teams are geographically spread out over a wide area (a common situation for leagues in North America) may face significant travel costs. One solution is to play an unbalanced schedule, with some teams playing additional games against some other teams; this is the way Major League Soccer has traditionally been scheduled, with the additional games being played against local rivals. Some leagues also break the league into subunits, often known as ''divisions'' and ''conferences'', each of which may itself play a balanced or unbalanced schedule.


Central venue leagues

A "central venue league" (CVL) is a sports league where all the fixtures take place at the same venue, instead of rotating around the venues of the 'home' team, for each fixture. Several UK basketball leagues operate on this basis, intended to keep the costs of participation as low as possible,Community Basketball League

Cups, tournaments, and playoffs

Many sports leagues also participate in a single-elimination tournament each year. In the United States, Mexico, and some other countries, these tournaments are commonly called "playoffs" and are played at the end of the season, with the teams qualifying for the playoffs based on their performance during the season. In Europe, "cup" competitions are more common, with all teams playing in a single-elimination tournament that takes place during and parallel with the regular season.
