The cricketing world is mourning the loss of Frank Duckworth, the English statistician and co-creator of the Duckworth-Lewis-Stern (DLS) method. Frank Duckworth passed away last Friday, June 21, at the age of 82. Alongside Tony Lewis, Duckworth devised the Duckworth-Lewis System in 1997, a mathematical formula that has since become the gold standard for revising targets in rain-affected cricket matches. The International Cricket Council (ICC) officially adopted this method in 2001, recognizing its profound impact on the sport.
The DLS method, named after Duckworth and Lewis, aims to provide a fair outcome in limited-overs cricket matches affected by weather interruptions, using a complex formula that factors in wickets lost and runs scored to compute revised targets. This method replaced the previously used, often criticized, average run rate method, which was widely seen as flawed and unfair in many scenarios.
Frank Duckworth’s innovation was brought into the limelight once again during the ongoing ICC T20 World Cup 2024. In a dramatic match on Monday, June 24, Afghanistan narrowly beat Bangladesh by eight runs in Kingstown to secure a place in the semifinals. Here, the DLS method played a vital role in determining the revised target in the rain-hit match, showcasing the enduring relevance and critical importance of Duckworth’s contribution to the game.
The genesis of the DLS method can be traced back to Duckworth’s keen interest in cricket statistics and his mathematical prowess. Both Frank Duckworth and Tony Lewis were professional statisticians who saw a pressing need for a more reliable and equitable system after observing the shortcomings of the existing methods. Duckworth’s collaboration with Lewis began in the mid-’90s, and their shared passion for cricket led them to develop the DLS method, which was first trialed in 1996 before gaining formal acceptance.
Before this groundbreaking invention, completing a cricket match interrupted by inclement weather often left players, fans, and officials dissatisfied with the results, leading to significant controversies. Duckworth’s system, carefully calculated and thoroughly tested, brought a scientific approach to resolving these issues that satisfied the cricket community’s need for fairness.
Beyond his monumental contribution to cricket, Frank Duckworth had a distinguished career as a statistician. Educated at the University of Cambridge, Duckworth specialized in Operational Research and later became a fellow of the Royal Statistical Society. He also served as a lecturer at the University of Salford, where he imparted his vast knowledge to students, many of whom went on to make their mark in various fields of research and analytics.

Tributes to Duckworth from the cricketing community have been heartfelt and plentiful. ICC Chair Greg Barclay stated, “Frank Duckworth’s contribution to cricket goes beyond the numbers; he brought fairness and accuracy to a situation that often left teams with a sense of injustice. His legacy will live on every time the DLS method is applied, continuing to ensure fair play in the sport he loved.”
Former cricketers also expressed their admiration. Sachin Tendulkar, one of cricket’s greatest legends, tweeted, “Deeply saddened by the passing of Frank Duckworth. His work, through the DLS method, brought much-needed clarity to rain-affected games. My condolences to his family and loved ones.”
Not just limited to men’s cricket, the DLS method has also played a significant role in women’s cricket. Clare Connor, the Managing Director of England Women’s Cricket, noted the importance of Duckworth’s contributions: “Frank’s work has been pivotal in guaranteeing that rain-affected matches in women’s cricket are resolved fairly. His passion for the game was evident, and he leaves behind a remarkable legacy.”
The impact of Duckworth’s work resonates globally, underscoring the universal importance of fairness and equal opportunity in sports. The DLS formula he co-created is now integral to every international cricket match played under the ICC’s auspices when weather disrupts play.
Frank Duckworth’s passing marks the end of an era for cricket, but his legacy will undoubtedly endure. He transformed the way cricket matches are adjudicated in adverse weather conditions, contributing to the game’s integrity and fairness. As players and fans worldwide remember Frank Duckworth, they will undoubtedly celebrate the intellect and dedication he brought to the sport. Cricket history will forever be grateful for his pivotal role in enhancing the game’s spirit and fairness.
