LONDON (AFP) - Tony Lewis, one of the men at the back of the Duckworth-Lewis-Stern approach utilized in climate-affected limited overs cricket fits, has died aged 78, the england and Wales Cricket Board introduced Wednesday.

"it's far with tons sadness that the ECB has learned of the passing of Tony Lewis MBE, elderly seventy eight," stated a announcement.

"Tony, alongside fellow mathematician Frank Duckworth, devised the Duckworth-Lewis method which changed into delivered in 1997 and adopted formally with the aid of the ICC (global Cricket Council) in 1999.


"Renamed the Duckworth-Lewis-Stern method in 2014, the mathematical formula continues to be utilized in rain reduced restricted overs cricket games across the globe."

The components befell in reaction to the incredible climax of a rain-interrupted 1992 international Cup semi-final in Sydney.

The method then in use become based totally on disposing of the lowest-scoring overs from every team s innings.

however it produced a farcical finish to a showpiece semi-final when South Africa, who had confronted the tough however conceivable target of 22 runs off 13 balls to beat England, have been left with the not possible assignment of scoring 21 runs off one ball after a rain put off.

Duckworth, the extra outspoken of the founding duo -- fellow statistician Steven Stern helped revise the components several years later -- said: "I don't forget hearing (commentator) Christopher Martin-Jenkins on radio pronouncing  clearly a person, somewhere could give you some thing better  and i quickly realised that it became a mathematical problem that required a mathematical solution."

The massive distinction between Duckworth-Lewis and former strategies was that it gave credit to aspects defending a target for taking wickets as well as chasing aspects for scoring runs.

considerably, this intended the goal might be adjusted proportionately in the event of a couple of stoppage.

an enduring criticism of the system is that it is difficult to understand with out getting access to a chart that shows wherein groups need to be over by means of over, for however many wickets they have lost.

however the sight of a D/L target soon became a acquainted characteristic on cricket scoreboards around the world.

numerous sides, however, have still burdened the goal had to tie with the full they require to win, with co-hosts South Africa being knocked out of the 2003 world Cup once they made this error against Sri Lanka in Durban.

The formulation has additionally been criticised for not being acceptable to Twenty20 matches, cricket s shortest format, which got here into being after Duckworth-Lewis turned into set up.
