CRICKET was difficult enough to understand before the World Cup. It has now become incomprehensible – and that’s official. Steve Waugh admitted earlier in the tournament he did not understand the scoring adjustments for rain-affected games, as worked out by the well-received but little understood Duckworth/Lewis system. On Saturday, meanwhile, Zimbabwe captain Alistair Campbell announced he was delighted with his side’s shock victory over mighty South Africa. But he had no idea whether it meant his side had qualified for the second round (it had). He might have been able to work it out if he had received an official communique to help him – or perhaps not. With the South Africans already qualified, the communique explained, two teams out of Zimbabwe, England and India, who were all in action on Saturday, would qualify. Which ones depended on complicated calculatoins of win margins and run rates.
