A Second Look at Duckworth and Lewis in Twenty20 Cricket


This project investigates the suitability of the Duckworth-Lewis method as an approach to resetting targets in interrupted Twenty20 cricket matches. Whereas the Duckworth-Lewis method has been adopted in both international Twenty20 matches and in the Indian Premier League, there has been growing objections to its use. In this project, we develop methodology for the estimation of a resource table designed for Twenty20 cricket. The approach differs from previous analyses in the literature by considering an enhanced dataset. It is suggested that there exist meaningful differences in the scoring patterns between one-day cricket and Twenty20.
