Tony Lewis, one of the men behind the Duckworth-Lewis-Stern method used in weather-affected limited overs cricket matches, has died aged 78, the England and Wales Cricket Board announced yesterday.
Tony, alongside fellow mathematician Frank Duckworth, devised the Duckworth-Lewis method which was introduced in 1997 and adopted officially by the ICC (International Cricket Council) in 1999.
Renamed the Duckworth-Lewis-Stern Method in 2014, the mathematical formula continues to be used in rain-reduced limited overs cricket games across the globe.
The method then in use was based on removing the lowest-scoring overs from each team’s innings.
The formula has been criticised for not being suited to Twenty20 matches, cricket’s shortest format, which came into being after Duckworth-Lewis was established.
No alternative method, however, has yet found favour with the ICC.
