<P> A Twenty20 International (T20I) is an international cricket match between two teams, each having T20I status, as determined by the International Cricket Council . In a T20I, the two teams play a single innings each, which is restricted to a maximum of 20 overs . The format was originally introduced by the England and Wales Cricket Board for the county cricket competition with the first matches contested on 13 June 2003 between the English counties in the Twenty20 Cup . The first T20I took place on 17 February 2005 when Australia defeated New Zealand by 44 runs at Eden Park in Auckland, with Australian captain Ricky Ponting finishing not out on 98 . </P> <P> A century is a score of one hundred or more runs by a batsman in a single innings . This is regarded as a notable achievement . The first century in a T20I match was scored by Chris Gayle of the West Indies who made 117 against South Africa at the inaugural ICC World Twenty20 in 2007 . South Africa won the match, one of only seven occurrences which did not result in a victory to the team with the player scoring the century . The most recent century was scored by Martin Guptill of New Zealand against Australia during the 2017--18 Trans - Tasman Tri-Series . New Zealand's Colin Munro leads the list with three T20I centuries, followed by his compatriots Guptill and Brendon McCullum, West Indians Gayle and Evin Lewis, India's Rohit Sharma and Glenn Maxwell of Australia with two each . Lewis' first century came during the 2016 series against India at the Central Broward Regional Park in Lauderhill, Florida . In reply, India's K.L. Rahul finished on 110 not out, the only occasion where two T20I centuries were scored in the same match . Rahul's innings is one of the eight instances where a batsman scored a century in the second innings of a T20I match . In August 2013, Australia's Aaron Finch posted the highest score in a T20I match with 156 while Rohit Sharma and David Miller of South Africa share the record for the fastest century, both reaching the milestone from 35 deliveries . Miller was also the first player to score a T20I century batting at number five or lower . </P> <P> As of 13 March 2018, 32 centuries have been scored by 24 different players from 659 T20I matches . Players from all teams that have permanent T20I status--with the exception of Zimbabwe and Ireland--have made centuries and of the teams that have temporary T20I status only Scotland, Hong Kong and the United Arab Emirates have had a player reach triple figures . No players from teams that have previously held temporary T20I status have scored centuries, with Hiral Patel from Canada coming the closest with 88 not out against Ireland in 2010 . New Zealand lead the list with seven centuries, followed by Australia, India, South Africa and the West Indies with four . Centuries have been scored at 26 different grounds, with Pallekele International Cricket Stadium in Kandy, Sri Lanka, leading the list with three . </P>
