The Bangladesh Cricket Board (BCB) expresses deep sadness at the passing away of mathematician and statistician Tony Lewis, co-creator of what is now known as the Duckworth-Lewis-Stern (DLS) method for deciding weather-affected limited-overs matches. Lewis was 78.

Offering his tribute, BCB CEO Nizam Uddin Chowdhury said: “Tony Lewis revolutionised the game of cricket with a method that is considered the fairest in settling weather-interrupted games. His contribution will be forever remembered.”

Lewis and fellow statistician Frank Duckworth had co-devised the system originally called the Duckworth-Lewis method which was first used in 1997 and officially endorsed by the International Cricket Council (ICC) in 1999. The system calculates targets based on the batting team’s wickets in hand, and overs in hand via mathematical formulas. In 2014, Professor Steven Stern of Australia’s Bond University   became the custodian of the system following the retirements of Duckworth and Lewis.
