Tony Lewis of 'DLS method' fame passes away
London, April 2: Tony Lewis, the man renowned for devising cricket's Duckworth-Lewis rain rules, has died. He was 78.
In 1999, Lewis in conjunction with his fellow mathematician Frank Duckworth, devised the rule which was officially adopted by the ICC to help calculate fair run-chases in the event of overs being lost to rain during that summer's World Cup, reports ESPNcricinfo.
