Anthony John Lewis MBE (25 February 1942 – 15 March 2020) [1] was a mathematician who, along with Frank Duckworth, developed the Duckworth–Lewis method of resetting targets in interrupted limited-overs cricket matches. [2] [3]


Personal life

Lewis was born in Bolton, Lancashire. He attended Kirkham Grammar School and graduated from Sheffield University with a degree in Mathematics and Statistics. [4]

Lewis was appointed Member of the Order of the British Empire (MBE) in the 2010 Birthday Honours. [5] [6]

Lewis died on 15 March 2020, aged 78. [1] [7]


Lewis was formerly a lecturer at the University of the West of England (UWE). [5] In January 2008, he retired as a lecturer in Quantitative Research Methods from Oxford Brookes University. [8]

He was also a former chairman of the Western Operational Research Discussion Society [ citation needed ] and was a keynote speaker at the Second IMA International Conference on Mathematics in Sport in 2009. [4] Lewis also undertook various consultancy roles in England and Australia. [8]

Duckworth-Lewis Method

In the 1980s, Frank Duckworth had proposed a method of resetting targets in interrupted limited-overs cricket matches. [9] After the 1992 Cricket World Cup, commentator Christopher Martin-Jenkins asked for a better calculation system. [9] Lewis read Duckworth's 1992 paper Fair Play in Foul Weather and together they devised the Duckworth-Lewis Method. [9] In 2014, Steven Stern became custodian of the method, and it was renamed the Duckworth–Lewis–Stern method. [5] [9]

1992 Cricket World Cup Cricket World Cup

The 1992 Cricket World Cup was the fifth staging of the Cricket World Cup, organised by the International Cricket Council (ICC). It was held in Australia and New Zealand from 22 February to 25 March 1992, and finished with Pakistan beating England by 22 runs in the final to become the World Cup champions for the first time.

One Day International Form of limited overs cricket, 50-over format

A One Day International (ODI) is a form of limited overs cricket, played between two teams with international status, in which each team faces a fixed number of overs, currently 50, with the game lasting up to 8 hours. The Cricket World Cup, generally held every four years, is played in this format. One Day International matches are also called Limited Overs Internationals (LOI), although this generic term may also refer to Twenty20 International matches. They are major matches and considered the highest standard of List A, limited-overs competition.

Duckworth–Lewis–Stern method Statistical method for calculating target scores in rain affected cricket matches

The Duckworth–Lewis–Stern method (DLS) is a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. The method was devised by two English statisticians, Frank Duckworth and Tony Lewis, and was formerly known as the Duckworth–Lewis method (D/L). It was introduced in 1997, and adopted officially by the ICC in 1999. After the retirements of Duckworth and Lewis, Professor Steven Stern became the custodian of the method and it was renamed to its current title in November 2014.

William Howard Frindall, was an English cricket scorer and statistician, who was familiar to cricket followers as a member of the Test Match Special commentary team on BBC radio. He was nicknamed the Bearded Wonder by Brian Johnston for his ability to research the most obscure cricketing facts in moments, while continuing to keep perfect scorecards and because he had a beard. Angus Fraser described Frindall as "the doyen of cricket scorers" in his obituary in The Independent.

Cedric Austen Bardell Smith was a British statistician and geneticist. Smith was born in Leicester. He was the younger son of John Bardell Smith (1876–1950), a mechanical engineer, and Ada. He was educated at Wyggeston Grammar School for Boys until 1929, when the family moved to London. His education continued at Bec School, Tooting, for three years, then at University College School, London. In 1935, although having failed his Higher School Certificate, he was awarded an exhibition to Trinity College, Cambridge. He graduated in the Mathematical Tripos, with a First in Part II in 1937 and a Distinction in Part III in 1938. Following graduation he began postgraduate research, taking his PhD in 1942.

Frank Carter Duckworth MBE is a retired English statistician, and is one of the two statisticians who developed the Duckworth–Lewis method of resetting targets in interrupted one-day cricket matches. He attended King Edward VII School, Lytham, now part of King Edward VII and Queen Mary School, then went on to study physics and earned a PhD (1965) in metallurgy, both at the University of Liverpool. Prior to his retirement, he worked as a mathematical scientist for the English nuclear power industry. He was a consultant statistician to the International Cricket Council, and the editor of the Royal Statistical Society's monthly news magazine, RSS News, until he retired from both these roles in 2014. He also served on the editorial board of Significance before stepping down in 2010. In 2004 he delivered the Royal Statistical Society Schools Lecture, entitled Lies and Statistics.

The 2017–18 Trans-Tasman Tri-Series was a Twenty20 International (T20I) cricket tournament that was held in Australia and New Zealand in February 2018. It was a tri-nation series between Australia, England and New Zealand.

It was the first T20I tri-series contested by full ICC members.

The Average Run Rate (ARR) method was a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. Often matches interrupted by weather would use reserve days, bowl outs, or be replayed on another date, but if logistics did not allow these, the ARR method would be used.

The Most Productive Overs (MPO) method was a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances.
