Frank Duckworth, one of the pioneering minds behind the Duckworth-Lewis-Stern (DLS) method, passed away at the age of 84.
Duckworth’s contribution to the game has left an indelible mark, revolutionizing how rain-affected matches are determined. The Duckworth-Lewis method, initially formulated by Frank Duckworth and Tony Lewis in 1997, transformed how cricket matches are adjusted during rain interruptions.
The DLS method is based on a complex statistical analysis that considers many factors, such as wickets remaining and overs lost, to set a revised target for the team batting second.
In 2014, the system was renamed the Duckworth-Lewis-Stern method after Professor Steven Stern was appointed the custodian of the method, making necessary adjustments to adapt to modern cricket’s evolving dynamics. It was during the 1997 Women’s ODI World Cup, held in India, that the DLS method was first used. It was first applied in a match between the Netherlands and New Zealand, which was reduced to 20 overs for both teams. This tournament saw the DLS method being applied to adjust targets in rain-affected matches, ensuring fair play and maintaining the competitive balance of the games.
Duckworth-Lewis’ innovation replaced the much-criticized rain rule previously used, which famously marred the 1992 ODI World Cup semi final between South Africa and England in Sydney. In that match, a sudden downpour and the subsequent application of the rain rule led to a farcical situation where South Africa needed an impossible 22 runs off one ball, highlighting the urgent need for a more equitable solution.
His work has been celebrated in the cricketing world, offering a mathematical solution to a longstanding problem in cricket.
