A Twenty20 International (T20I) is a form of cricket, played between two of the top members of the International Cricket Council (ICC), in which each team faces 20 overs. The matches have top-class status and are the highest T20 standard. The game is played under the rules of Twenty20 cricket. ICC decided to use DRS in Twenty20 internationals from October 2017.
The shortened format was initially introduced to bolster crowds for the domestic game, and was not intended to be played internationally, but the first Twenty20 International took place on 17 February 2005 when Australia defeated New Zealand, and the first tournament was played two years later, with the introduction of the ICC World Twenty20. In 2016, for the first time in a calendar year, more Twenty20 International matches(100) were played than ODI matches(99). There remain limits on how many Twenty20 Internationals a team can play each year, in order to protect Test cricket and One Day Internationals. As of 2016, there are 18 nations that feature in ICC T20I team rankings.
The shorter format of the game makes reaching the traditional milestones of scoring a century or taking five wickets in an innings more difficult, and few players have achieved these. The highest individual score in a Twenty20 International is 156, made by Australia's Aaron Finch against England in 2013, while Sri Lanka's Ajantha Mendis is the only bowler to have taken two six wickets in an innings, and fewer than twenty players have taken five wickets in an innings.
Cricket itself was probably first played in England in the Late Middle Ages, but it did not rise to prominence until the eighteenth century. A set of laws were drawn up in 1744, and the game achieved a level of relative standardisation by the late nineteenth century. One-day cricket was trialled in 1962, and the first domestic tournament played the following year, and in 1971, England and Australia contested the first One Day International. The match consisted of one innings for each side, with 40 eight-ball overs.
In the 1990s, a number of countries were exploring the possibility of a shorter game still: in New Zealand, Martin Crowe developed Cricket Max, in which each team bats for 10 eight-ball overs, while in Australia they considered an eight-a-side contest they dubbed "Super 8s". At the same time, the England and Wales Cricket Board (ECB) conducted consumer research, and proposed the idea of a 20 overs-per-side contest, which would last for about three hours. The first match was played in 2003 between Hampshire and Sussex.
The first Twenty20 International match between two men's sides was played on 17 February 2005, involving Australia and New Zealand. Wisden Cricketers' Almanack reported that "neither side took the game especially seriously", and it was noted by ESPNcricinfo that but for a large score for Ricky Ponting, "the concept would have shuddered". However, Ponting himself said "if it does become an international game then I'm sure the novelty won't be there all the time".
Two further matches were played that year; England beat Australia in June, and South Africa were defeated by New Zealand in October. Early the following year, a contest between New Zealand and the West Indies finished as the first tied match, and a tiebreak was played for the first time in men's international cricket: the two sides took part in a bowl-out to determine a winner; New Zealand won 3–0.
The game had initially been developed to boost the interest in domestic cricket, and to aid this the international teams were only allowed to host three T20Is each year. The cricket manager for the ICC, David Richardson, also commented that "Part of the success of Twenty20 cricket is making sure it can coexist with Test cricket and one-dayers." Despite this, the first international tournament was held in 2007 in South Africa; the 2007 ICC World Twenty20. That tournament was won by India, who defeated their close rivals Pakistan in the final. Writing for The Guardian, Dilip Premachandran suggested that the competition's success meant that "the format is here to stay". The next tournament was scheduled for 2009, and it was decided that they would take place biannually (more frequently than the 50 over Cricket World Cup, which occurs once every four years). In the opening match of the 2007 World Twenty20, Chris Gayle scored the first century in a T20I, the achievement being reached in the twentieth match of the format.
Teams with T20I status
The ten Test-playing nations (which are also the ten full members of the ICC) have permanent T20I status. The nations are listed below with the date of each nation's T20I debut shown in brackets:
- New Zealand (17 February 2005)
- Australia (17 February 2005)
- England (13 June 2005)
- South Africa (21 October 2005)
- West Indies (16 February 2006)
- Sri Lanka (15 June 2006)
- Pakistan (28 August 2006)
- Bangladesh (28 November 2006)
- Zimbabwe (28 November 2006)
- India (1 December 2006)
Since 2005, the ICC has granted temporary ODI and T20I status to six other teams (known as Associate/Affiliate members). Teams earn this temporary status for a period of four years based on their performance in the quadrennial ICC World Cricket League – or, more specifically, based on the top six finishing positions at the ICC World Cup Qualifier, which is the final event of the World Cricket League. On 28 June 2014, the ICC granted T20I status to Nepal and Netherlands, both of whom qualified for and took part in the 2014 ICC World Twenty20, but had both failed to gain/retain ODI status. The following eight teams currently have this status (the dates listed in brackets are of their first T20I match after gaining temporary ODI or T20I status):
Four other Associate Nations have held temporary ODI and T20I status as a result of World Cricket League performances, before being relegated after underperforming at the World Cup or World Twenty20 Qualifier:
Cricket at international multi-sport events
Cricket was played as part of the 1900 Summer Olympics, when England and France contested a two-day match. In 1998, cricket was played as part of the Commonwealth Games, on this occasion in the 50-over format. There was some talk about Twenty20 cricket being part of the 2010 Commonwealth Games, which were held in Delhi, but at the time the Board of Control for Cricket in India (BCCI), were not in favour of the short format of the game, and it was not included.
Cricket was played in 2010 Asian Games in Guangzhou, China and 2014 Asian Games in Incheon, South Korea. India skipped both times. There was further calls for subsequent Commonwealth Games and Olympic Games. The Commonwealth Games Federation asked the ICC to participate in the 2014 and 2018 Commonwealth Games, but the ICC turned down the invitation. In 2010, the International Olympic Committee recognised cricket as a sport which could apply to be included in the Olympic Games, but in 2013 the ICC announced that it had no intentions to make such an application, primarily due to opposition from the BCCI. ESPNcricinfo suggested that the opposition might be based on the possible loss of income. In April 2016, ICC chief executive David Richardson said that Twenty20 cricket can have a chance of getting in for the 2024 Summer Games, but there must be collective support shown by the ICC's membership base, in particular from BCCI, in order for there to be a chance of inclusion.
The highest team total in a T20I was made by Australia in September 2016, against Sri Lanka. Australia scored 263 runs for the loss of three wickets (263/3). The lowest total also came in a match involving Sri Lanka: in 2014, the Netherlands were bowled out for just 39 runs against them. The highest successful chase was made in early 2015, when the West Indies scored 236 runs to overhaul South Africa's target and win the match.
Brendon McCullum has accrued the most runs in the format, and is the only batsman to have scored more than 2,000 runs. He is one of less than twenty players to have scored a century in T20Is, and as of February 2015, the only one to have done so twice. The highest total in a T20I though, was scored by Aaron Finch, who totalled 156 runs in a match against England in 2013. Three Pakistani bowlers lead the records for the most wickets; each having taken over 80 in T20Is: Saeed Ajmal, Umar Gul and Shahid Afridi. Similarly, Sri Lanka's Ajantha Mendis has recorded the best two set of bowling figures in T20Is, and is the only bowler to have taken six wickets in a match, doing so against both Zimbabwe in 2012, and Australia in 2011. Virat Kohli is the fastest cricketer to score 1000 runs in Twenty20 Internationals in 27 innings.
