This rule was first introduced in 1991 but in recent times this rule has undergone major changes. This only applies to one-day matches. A maximum of two fielders can be outside the 30 yard circle in the first 10 overs power play. At any time between 18 and 40 overs, the batting team can choose 5 overs and the bowling team can choose 5 overs power play , at which time maximum 3 people can be out of 30 yards.
