# Tony Lewis the 'Duckworth-Lewis-Stern method' cricket fame dies, aged 78.

Tony Lewis, was one of the two men behind the Duckworth-Lewis-Stern method (DLS method) which is used to have judgement for winning prospect of the weather-affected limited overs cricket matches, has died aged 78.

The UK origin statistician Frank Duckworth and  cricketer Tony Lewis co-developed the DLS Stern system of calculating target scores in rain-affected matches. Tony was in alongside with fellow statistician Frank Duckworth to device the Duckworth-Lewis method which was introduced in 1997 and adopted officially by the ICC (International Cricket Council) in 1999. In 2014 the method was renamed and to be used in rain reduced limited overs cricket games across the globe.

The DLS formula came about in response to the extraordinary climax of a rain-interrupted 1992 World Cup semi-final in Sydney.The method in that time in use was based on removing the lowest-scoring overs from each team's innings.

But it produced a farcical finishes in several innings and the big difference between Duckworth-Lewis and previous methods was that it gave credit to sides defending a target for taking wickets as well as chasing sides for scoring runs.

The big distinguished difference between Duckworth-Lewis and previous methods was that it gave credit to sides defending a target for taking wickets as well as chasing sides for scoring runs. That means the target could be adjusted proportionately in the event of more than one stoppage.

However, the DLS formula has also been criticized for not being suited to Twenty20 matches, cricket's shortest format, which came into being after Duckworth-Lewis was established.
