Birth of DLS Method ft Frank Duckworth
Alongside fellow statistician Tony Lewis, Frank Duckworth devised the DLS method to ensure fair target adjustments when rain disrupts limited-overs cricket matches.
Officially adopted by the International Cricket Council (ICC) in 1999, the DLS method continues to be the gold standard for resolving rain-affected matches.
From Metallurgy to Statistics: Frank Duckworth
The Royal Statistical Society (RSS) paid tribute to Frank Duckworth, highlighting his contributions as the editor of their newsletter and his lasting impact on cricket through the DLS method.
Although originally trained in metallurgy, Duckworth’s passion for statistics led him to develop a method that addressed a long-standing challenge in cricket.
Inspired by Injustice: DLS method emerges
Duckworth’s ingenuity was sparked by the controversial ending of the 1992 World Cup semi-final between England and South Africa. A brief downpour resulted in an unfair target for South Africa, leaving them needing an improbable 22 runs off a single ball.
This incident motivated Duckworth to present a paper titled “A fair result in foul weather” at an RSS conference in 1992.
Collaboration and Refinement: DLS Takes Shape
Frank Duckworth’s paper led him to collaborate with Tony Lewis. Their combined efforts produced a formula that was first implemented in a one-day series between England and Zimbabwe in 1999.
Following ‘Duckworth and Lewis’ retirement, the method was further refined by Australian statistician Steven Stern, becoming known as the Duckworth-Lewis-Stern method.
