Frank Duckworth, co-inventor of the DLS method, passes away at 84
Frank Duckworth, the English statistician who co-invented the Duckworth-Lewis-Stern (DLS) method for cricket, passed away on June 21 at the age of 84, according to a report by ESPNcricinfo.
Duckworth, along with fellow statistician Tony Lewis, developed the method to determine results in rain-affected cricket matches. The Duckworth-Lewis method was first used in international cricket in 1997 and became the standard method adopted by the ICC in 2001. Later, the method was renamed to include Australian statistician Steven Stern, who made modifications to it.
Duckworth and Lewis were both awarded MBEs (Member of the Order of the British Empire) in June 2010 for their contributions to cricket. The DLS method uses complex statistical analysis to set revised targets for teams batting second, taking into account factors like wickets remaining and overs lost.
