Frank Duckworth, one of the inventors of the Duckworth-Lewis-Stern (DLS) method, passed away on June 21. He was 84.
The Duckworth-Lewis method, devised by Duckworth and fellow statistician Tony Lewis, was introduced to determine results in rain-affected cricket matches. Lewis had passed away aged 78 in 2020.
The method was first used in international cricket in 1997 and was formally adopted by the ICC as the standard method for setting revised targets in truncated games in 2001.
It was used as recently as Tuesday in the ongoing T20 World Cup when Afghanistan defeated Bangladesh in a rain affected match to qualify for their first semifinal in history.
Before the method was introduced, authorities were stumped on how to create a fair run chase in weather-hit limited overs cricket matches.
