you don not know these ONE DAY INTERNATIONAL CRICKET RULES
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-day International and between forty and sixty in a List A domestic one-day match. Other changes to the game include additional restrictions on where fielders may be placed (preventing teams from placing every fielder on the edge of the field to prevent boundaries), a restriction on the number of overs that may be bowled by any one bowler and stricter rules on wide balls and short deliveries (to prevent teams from restricting scoring by bowling deliveries that batsmen have no chance to score from). In many games a white ball is used rather than the traditional red; the need to paint rather than stain the white ball gives it subtly different characteristics in flight as it wears.
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. However, many fans of Test match cricket regard it as ignoring the skills of bowlers, prone to random results not reflective of the relative skill of the teams, and with modern one-day tactics where batsmen take few risks outside the first and last few overs, lacking in the claimed excitement. Such criticisms have gained steam with the revitalisation, led by Australia, of Test matches.
Bowling restrictions In ONE DAY INTERNATIONAL CRICKET (ODI)
As mentioned above, in almost all competitive one-day games, a restriction is placed on the number of overs that may be bowled by any one bowler. This is to prevent a side playing two bowlers with extremely good stamina who can then bowl the entirety of their side’s overs, thus skewing the composition of a side. The classical composition of a cricket team is five specialist batsmen, five specialist bowlers and a wicket-keeper: in order to maintain this, the usual limitation is set so that a side must include at least five bowlers. For example, the usual limit for twenty-over cricket is four overs per bowler, for forty-over cricket eight per bowler and for fifty-over cricket ten per bowler.
There is at least one notable exception to this convention. Pro Cricket in the United States restricts bowlers to five overs each, thus leaving a side requiring only four bowlers.
