Shaughnessy playoff system

Last updated

The Shaughnessy playoff system is a method of determining the champion of a sports league that is not in a divisional alignment. This format is also known as the Argus finals system. It involves the participation of the top four teams in the league standings in a single elimination tournament. [1] [2] While the first round of the playoffs involve the pairing of the first- and fourth-place teams in one contest (whether it be a single game or a series of games) and the second- and third-place teams in the other, [3] a variant of the Shaughnessy playoffs would pair the first- and third-place teams in one semifinal round and the second- and fourth-place teams in the other. In either variant, the winners of the first two games would then compete for the league championship. Some lower-level leagues use a Shaughnessy playoff for purposes of promotion to the next-higher league.

Another variant of the Shaughnessy system exempts a certain number of top teams from the playoffs (usually one to three teams) and instead involves the next four teams in the league standings. This variation is almost always used by a lower-level league for promotion purposes. Typically, the exempted top finishers earn automatic promotion and the playoffs determine the final promotion place.

History and usage

North America

The Shaughnessy playoff system was implemented in 1933 by Frank Shaughnessy, the general manager of the Montreal Royals minor league baseball team of the International League. After its successful implementation by the International League, the popularity of the new postseason format spread to other baseball leagues, including to the Texas League in 1933 [4] and to the Western Baseball League, [5] Evangeline League, [6] and Southern Association in 1935. [7]

In the 1940s, the Shaughnessy system spread to other sports. The All-America Football Conference, which used the Shaughnessy playoff system in 1949, the last season of the league's existence, [8] and the American Association minor American football league used the format in five of its championship seasons during that decade. [9]

In the Original Six era of the National Hockey League (1942–1967), the circuit adopted a Shaughnessy playoff system (first place vs. third place and second place vs. fourth place) in which the paired teams played in a best-four-of-seven-games series with the winners advancing to the Stanley Cup championship round. A Shaughnessy-style format is used in today's NHL in an entirely different context—since 2016, the All-Star Game has been contested as a four-team knockout tournament, with each team drawn exclusively from one of the league's four divisions. Each "game" is played in a three-on-three format (i.e., three skaters and one goaltender, unless affected by penalties) over a single 20-minute period (the same length of a period in a regular NHL game).

From its first season in 2013 through 2020, the National Women's Soccer League used a Shaughnessy playoff (using 1–4 and 2–3 semifinal pairings) to determine its champion. The league expanded its playoffs to six teams in 2021.

In NCAA college basketball, one Division I conference uses a Shaughnessy playoff for its postseason tournaments for men and women. The Ivy League launched postseason tournaments for both sexes in the 2016–17 season; the top four teams in the regular-season conference standings advance to a Shaughnessy tournament (also using 1–4 and 2–3 semifinal pairings) at a predetermined site. The winners receive the Ivies' automatic berths in the NCAA men's and women's tournaments. [10]

Europe

More recently, the Shaughnessy playoff system has been adopted outside of North America. In English rugby union, the format is currently used to determine the winner of the Premiership, [11] and from 2012–13 through to 2016–17 [12] was also used in the second-level RFU Championship to determine the team to be promoted to the Premiership. [13] The Premiership and Championship formats differ only in the number of games contested—the Premiership playoff uses one-off matches, while all matches in the Championship playoff were two-legged. The Premier 15s, launched in autumn 2017 as the new top flight of English women's rugby, uses the same playoff format as the Premiership. The Celtic League in Ireland, Scotland and Wales, now known as Pro14, adopted a system identical to that of the Premiership starting in 2009–10, the season before that league expanded to include two teams from Italy. The Shaughnessy system was replaced by a six-team playoff when two South African sides joined the league in 2017–18, bringing it to its current 14-team roster.

In French rugby union, a Shaughnessy-style playoff was used to determine the second of two promotion spots in the second-tier Rugby Pro D2 through the 2016–17 season, with the teams involved being the second- through fifth-placed teams, as the first-place team earned automatic promotion to the Top 14. This system has been abandoned for 2017–18 and beyond in favor of a six-team playoff system identical to that currently used in the Top 14, with only the Pro D2 champion earning automatic promotion and the runner-up advancing to a promotion/relegation playoff with the second-from-bottom Top 14 side. [14] Previously, the pure Shaughnessy system had been used to determine the Top 14 champion, but that league's playoffs expanded to six teams starting in 2009–10.

The Super League in rugby league, made up primarily of English sides with one from France, adopted a Shaughnessy playoff beginning in 2015. This follows a 22-match home-and-away league season and a single round-robin mini-league involving the top eight clubs from the home-and-away season. In addition, the second-level Championship adopted a Shaughnessy playoff for its Championship Shield, and the third-level League 1 adopted a Shaughnessy-style promotion playoff similar to that formerly used by Rugby Pro D2. In the Championship, the bottom eight teams at the end of the league season enter their own single round-robin mini-league, with the top four teams at the end of that phase entering a Shaughnessy playoff for the Shield. In League 1, the top team at the end of the league season is automatically promoted to the following season's Championship. The second- through fifth-place teams then enter a Shaughnessy-style playoff for the second promotion place.

Some association football leagues use Shaughnessy-style playoffs for promotion purposes. Among the countries using such a system are:

Southern Hemisphere

In rugby union, the Shaughnessy system has been widely used throughout the SANZAAR countries of South Africa, New Zealand, Australia and Argentina.

The Super Rugby competition, initially featuring teams from Australia, New Zealand and South Africa, used the Shaughnessy format throughout its history as the Super 12 and Super 14, ending in 2010. The competition's expansion to 15 teams as Super Rugby in 2011 saw the playoffs expand to six teams, with three conference champions and three "wild cards" advancing. With the addition of three more teams in 2016 (with two of the new entries in Argentina and Japan), the playoffs now involve eight teams, with four conference champions and four "wild cards". The format was discontinued in the Super Rugby competition for the 2017 season.

In South Africa, the Currie Cup uses a Shaughnessy playoff to determine the champions of both of its divisions (Premier and First).

In New Zealand, the professional Mitre 10 Cup (formerly Air New Zealand Cup and ITM Cup) adopted the Shaughnessy format in 2009, after having used an eight-team playoff bracket in its first two seasons in 2007 and 2008. In 2011, the then-ITM Cup split into two divisions, effectively re-creating the three-division system that existed in the National Provincial Championship era. The playoffs in both the Premiership and Championship divisions use the Shaughnessy system except in World Cup years, in which only the top two teams contest a final. Since its inception in 2007, the amateur Heartland Championship has used the Shaughnessy system, implemented at the last group stage, to determine the winners of both of its trophies, the Meads and Lochore Cups.

Australia's National Rugby Championship, which began play in 2014, uses a Shaughnessy playoff. The country's previous attempt to establish a national league, the Australian Rugby Championship, also used a Shaughnessy playoff, but was scrapped after its only season in 2007.

Philippines

A modified Shaughnessy system has been used by the University Athletic Association of the Philippines for its basketball tournaments since 1993. In the semifinals with a #1 vs. #4 and #2 vs. #3 match-ups, the top two seeds possessing the twice to beat advantage, a variant of the best of three series where the higher seed has 1–0 series lead. The winners advance to the best of three finals; it has never been referred to as the "Shaughnessy system" in the country. The National Collegiate Athletic Association (NCAA) adopted it for their basketball tournaments starting in 1998. It has since been adopted to other sports by other collegiate leagues, and in the Philippine Basketball Association, since then

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 either a single game, a series of games, or a tournament, and may use a single-elimination system or one of several other different playoff formats. Playoff, in regard to international fixtures, is to qualify or progress to the next round of a competition or tournament.

A tournament is a competition involving at least three competitors, all participating in a sport or game. More specifically, the term may be used in either of two overlapping senses:

  1. One or more competitions held at a single venue and concentrated into a relatively short time interval.
  2. A competition involving a number of matches, each involving a subset of the competitors, with the overall tournament winner determined based on the combined results of these individual matches. These are common in those sports and games where each match must involve a small number of competitors: often precisely two, as in most team sports, racket sports and combat sports, many card games and board games, and many forms of competitive debating. Such tournaments allow large numbers to compete against each other in spite of the restriction on numbers in a single match.

In an organized sports league, a typical season is the portion of one year in which regulated games of the sport are in session: for example, in Major League Baseball the season lasts approximately from the last week of March to the last week of September. In other team sports, like association football or basketball, it is generally from August or September to May although in some countries – such as Northern Europe or East Asia – the season starts in the spring and finishes in autumn, mainly due to weather conditions encountered during the winter.

Primarily in Australian sports, a grand final is a game that decides a sports league's premiership winning team, i.e. the conclusive game of a finals series. Synonymous with a championship game in North American sports, grand finals have become a significant part of Australian culture. The earliest leagues to feature a grand final were in Australian rules football, followed soon after by rugby league. Currently the largest grand finals are in the Australian Football League (AFL) and National Rugby League (NRL). Their popularity influenced other competitions such as soccer's A-League Men and A-League Women, the National Basketball League, Suncorp Super Netball and European rugby league's Super League to adopt grand finals as well. Most grand finals involve a prestigious award for the player voted best on field.

There are a number of formats used in various levels of competition in sports and games to determine an overall champion. Some of the most common are the single elimination, the best-of- series, the total points series more commonly known as on aggregate, and the round-robin tournament.

A wild card is a tournament or playoff berth awarded to an individual or team that fails to qualify in the normal way; for example, by having a high ranking or winning a qualifying stage. In some events, wildcards are chosen freely by the organizers. Other events have fixed rules. Some North American professional sports leagues compare the records of teams which did not qualify directly by winning a division or conference.

The Page playoff system is a playoff format used primarily in softball and curling at the championship level, and the Indian Premier League and Pakistan Super League cricket tournaments. Teams are seeded using a round-robin tournament and the top four play a mix of a single-elimination and double-elimination tournament to determine the winner. It is identical to a four-team McIntyre system playoff, first used by the WANFL, SANFL and VFL in Australia in 1931, originally called the Page–McIntyre system, after the VFL delegate, the Richmond Football Club's Secretary, Percy "Pip" Page, who had advocated its use. A form has been adopted in the Canadian Premier League national soccer competition.

Professional sports leagues are organized in numerous ways. The two most significant types are one that developed in Europe, characterized by a tiered structure using promotion and relegation in order to determine participation in a hierarchy of leagues or divisions, and a North American originated model characterized by its use of franchises, closed memberships, and minor leagues. Both these systems remain most common in their area of origin, although both systems are used worldwide.
