Since luck can play a big part in tournament success, team management should use more objective measures of performance. A Linear model is used to fit least squares ratings to margins of victory in the World Cup of cricket. The Duckworth/Lewis (D/L) rain interruption rules are applied to second innings victories to create a margin of victory in runs, equivalent to that for the team batting first. Results show that while the better (earns progressed through the first round of the competition, some injustices occurred in the Super-Six round. Ordering teams by average margin of victory in runs gives similar results to the linear model, and its official publication and use as a tie breaker is suggested.
