The International Cricket Council has released an updated version of the Duckworth-Lewis-Stern (DLS) system that determines the outcome in limited-overs matches shortened by rain. The latest update — the second, overall — is based upon detailed ball-by-ball analyses of scoring patterns and will be enforceable from Sunday, the ICC announced via a communique.
According to the analyses, “teams have been able to extend their acceleration patterns for longer periods, and the average scores in [One-Day Internationals] have continued to increase.” The knowledge that teams generally score “a slightly higher” proportion of their runs towards the end of their innings will now have an effect on the par-score calculations.

It has also been observed that “wicket-adjusted resource utilisation rates are essentially identical” in both formats, and in both men’s and women’s cricket. Therefore, according to the communique, a single DLS system will be compatible with all the mentioned scenarios.
Also beginning Sunday, changes in the ICC Code of Conduct will be enforced. These include the introduction of four new offences — attempting to gain an unfair advantage (cheating, other than ball tampering), personal abuse, audible obscenity, and disobeying an umpire’s instructions — and a change in the level of an existing offence. ‘Changing the condition of a ball’ has been escalated to a Level 3 offence (from two). The new offences range from Levels 1 and 3.
The ICC has also made “minor tweaks” to the existing playing conditions. It now allows for a match to be concluded before a scheduled interval, and, through Clause 19, mandates that “unless the boundary is the maximum 90 yards from the centre of the pitch, the boundary rope cannot be any more than 10 yards from the edge of the available playing area.”
