In the sport of cricket, a century is a score of hundred or more runs by a batsman in one innings. A Twenty20 International (T20I) is an international 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.
