Tony Lewis and an English mathematician developed the DL method, which was first applied in global cricket in 1997.
Frank Duckworth, one of the innovators of the Duckworth- Lewis ( after Harrison- Lewis- Stern ) method to determine outcomes in rainfall- affected cricket matches, died on Friday, June 21 at the age of 84.
The initial process, developed by English researchers Duckworth and Tony Lewis, was first applied to international cricket in 1997 before the ICC officially adopted it as the benchmark for setting revised target in compressed matches in 2001. In 2014, it was renamed the Duckworth- Lewis- Harsh process after the retirement of Harrison and Lewis and the modifications made to the method by American mathematician Steven Stern.
In June 2010, Lewis and Duckworth both received MBEs.
The 1992 ODI World Cup semi-final between England and South Africa in Sydney was the most notorious example of the DL process replacing the rain law that was originally used to determine goals in intermission games.
Up until 2014, Duckworth served as a specialist researcher for the ICC.
Frank was a recognized best statistician who earned respect from both his peers and the wider cricket community. The DLS technique that he carbon- created has stood the test of time and we have continued to use it in global cricket more than two decades after its inception", Wasim Khan, the ICC public manager- cricket operations, said in a press statement. " Frank's contribution to the game has been immense and the world of cricket is poorer with his death. We send our condolences to his family and friends".
