ODI Matches (One Day International) are played in the game of cricket. The game is usually very different when it is compared to a modern day test match as a ODI match has limited overs. The game will usually be 50 overs long, but it can vary.
Teams must try and score as many runs as they can before the 50 overs are up, so ODI's are usually very quick and aggressive compared to the safe play of test matches. ODI's are played with a white ball instead of the red ball used in tests. Bowlers are only allowed to bowl a limited amount of overs in a ODI compared to tests where they can have long spells.
One has to only look at the way One-DayInternationals are currently scheduled to appreciate the need for such a structured approach.
The above Triangular One-day schedule fits in perfectly with the PWC schedule for test matches, and all the ten test playing nations, including Bangladesh & Zimbabwe, take part in three one-day triangular tournaments every season, one at home and two away.
The selection of the ICC-member teams could be on the basis of their qualification to the One-DayInternational World-Cup.
In a one-day cricket match, each team bats only once, and each innings is limited to a set number of overs, usually fifty in a One-dayInternational and between forty and sixty in a List A domestic one-day match.
One-day cricket is popular with spectators as it can encourage aggressive, risky, entertaining batting, often results in cliffhanger endings, and ensures that a spectator can watch an entire match without committing to five days of continuous attendance.
One-dayInternational matches are usually played in brightly coloured clothing (leading some to give it the unflattering nickname pyjama cricket), and often in a "day-night" format where the first innings of the day occurs in the afternoon and the second occurs under stadium lights.
