Limited overs cricket
Limited overs cricket, also known as one-day cricket and in a slightly different context as List A cricket, is a version of the sport of cricket in which a match is generally completed in one day, whereas Test and first-class matches can take up to five days to complete. The name reflects the rule that in the match each team bowls a set maximum number of overs, usually between 20 and 50, although shorter and longer forms of limited overs cricket have been played.
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.
Structure
Each team bats only once, and each innings is limited to a set number of overs, usually fifty in a One Day International and between forty and sixty in a List A. List A is a classification of the limited-overs (one-day) form of cricket, technically as the domestic level.
