Frank Duckworth, co-inventor of Duckworth-Lewis method, passes away aged 84

Frank Duckworth MBE (Member of the Order of the British Empire), co-inventor of the widely acclaimed Duckworth-Lewis method, died on June 21 aged 84.

Duckworth devised the DLS method in 1999 along with fellow mathematician Tony Lewis MBE.

Their method was officially adopted by the ICC to help calculate fair run-chases in the event of overs being lost to rain during that summer's World Cup.

Their method was used today in the decisive tie between Afghanistan and Bangladesh in the T20 World Cup to derive the new target after rain affected an over in the match.

In 2014, the name of Steven Stern, an Australian professor from Queensland, was added to what is now known the method, now known as the ‘Duckworth-Lewis-Stern’ method, after he took over and made adjustments to the rule by taking into consideration modern day scoring rates.

The DLS method was first employed in 2015 World Cup played in Australia and New Zealand.

Duckworth and Lewis were awarded MBEs in 2010 for their services to cricket and mathematics.
