Twenty20 in the context of "List A"

Cricket was played at the 1900 Summer Olympics, a men's contest with only two entrants, won by Great Britain over France. It is scheduled to be included again in the 2028 Summer Olympics in Los Angeles, with men's and women's Twenty20 tournaments.

Cricket is a bat-and-ball game that is played between two teams of eleven players on a field, at the centre of which is a 22-yard (20-metre; 66-foot) pitch with a wicket at each end, each comprising two bails (small sticks) balanced on three stumps. Two players from the batting team, the striker and nonstriker, stand in front of either wicket holding bats, while one player from the fielding team, the bowler, bowls the ball toward the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball with the bat and then switch places with the nonstriker, with the batting team scoring one run for each of these swaps. Runs are also scored when the ball reaches the boundary of the field or when the ball is bowled illegally.

The fielding team aims to prevent runs by dismissing batters (so they are "out"). Dismissal can occur in various ways, including being bowled (when the ball hits the striker's wicket and dislodges the bails), and by the fielding side either catching the ball after it is hit by the bat but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease line in front of the wicket. When ten batters have been dismissed, the innings (playing phase) ends and the teams swap roles. Forms of cricket range from traditional Test matches played over five days to the newer Twenty20 format (also known as T20), in which each team bats for a single innings of 20 overs (each "over" being a set of 6 fair opportunities for the batting team to score) and the game generally lasts three to four hours.

Women's Twenty20 is the use of the Twenty20 match format in women's cricket. In a Twenty20 match, the two teams bat for a single innings each, of a maximum of 20 overs. The wider rules and playing conditions are usually the same for both the men's format and the women's format, with some small variations.

The first women's Twenty20 matches took place concurrently on 29 May 2004, as part of the 2004 Super Fours: Braves versus Super Strikers and Knight Riders versus V Team. These matches were viewed as a warm-up for the first Women's Twenty20 International (and first T20I for either gender), that took place at Hove on 5 August 2004 between England and New Zealand.

Cricket is a multi-faceted sport with different formats, depending on the standard of play, the desired level of formality, and the time available. One of the main differences is between matches limited by time in which the teams have two innings apiece, and those limited by number of overs in which they have a single innings each. The former, known as first-class cricket if played at the senior level, has a scheduled duration of three to five days (there have been examples of "timeless" matches too); the latter, known as limited overs cricket because each team bowls a limit of typically 50 overs, has a planned duration of one day only. A separate form of limited overs is Twenty20, originally designed so that the whole game could be played in a single evening (3 hours), in which each team has an innings limited to twenty overs.

Double innings matches usually have at least six hours of playing time each day, with formal intervals on each day for lunch and tea, and additional brief informal breaks for drinks. There is also a short interval between innings. Limited overs matches often last at least six hours, with similar intervals and breaks, whilst the more streamlined Twenty20 matches are generally completed in under four hours. T10 cricket is a newer version of the game, based on the principles of other limited overs formats, but with only 10 overs per innings, and the total playing time limited to 90 minutes.

The 2004 Super Fours was the third cricket Super Fours season. It took place in May and June and saw 4 teams compete in a 50 over league and, for the first time, a knockout Twenty20 tournament. V Team were the winners of both tournaments.
