The ICC's cricket committee has recommended the number of bouncers permitted in an ODI over be increased to two. They also concluded the bowling powerplay be removed and the number of fielders permitted outside the 30-yard circle reduced from five to four.
The committee's recommendations will be ratified by the ICC Board in Kuala Lumpur later this month, if they are incorporated into ODI playing conditions the mandatory Powerplay of 10 overs at the start of each innings will remain but only one period of five overs will now be nominated as a Powerplay, to be taken by the batting side and completed by the 40th over.
The changes are designed to "improve the balance between bat and ball and to create an identity for ODIs distinct from the Test and Twenty20 formats", an ICC release stated.
The committee decided there had been little impact from two five-over Powerplays being taken between the 16th and 40th overs, but did think using two new balls from each end had proven successful - both measures were recommended at last year's meeting.
"The changes will help enhance what is still an exceptionally popular form of the game," David Richardson, ICC General Manager of Cricket, said. "The committee was mindful of the need to avoid continual changes but was determined to complete the process initiated last year to enhance the format. It is now confident that these recommendations for ODI cricket, which showed its popularity during the 2011 World Cup will help create an even more attractive spectacle as we approach the World Cup in 2015."
Other recommendations of the committee, chaired by former West Indies captain Clive Lloyd, were that the Duckworth-Lewis (D/L) method of calculating scores in rain-affected matches should remain. An Indian mathematician, V Jayadevan, had proposed his system - the VJD method - replace D/L but the committee unanimously agreed there was no evidence of any significant flaws in the D/L method nor that any improvements could be offered by the VJD method.
In addition, to improve over-rates, it was recommended that drinks should not be brought onto the field other than at official drinks breaks and players should always assume a not-out decision following a review and be ready to immediately resume play after the decision is made.
