AUSTRALIA celebrated its cricket World Cup victory Monday as joy turned to sadness for captain Steve Waugh and twin brother Mark as their grandfather died just hours after the win. Edward Waugh, 89, died at a northern New South Wales hospital just hours after the Australians, led by the Waugh twins, thrashed Pakistan in the World Cup final at Lord’s. The twins had vowed to win the Cup for their ailing “Pop”, but never got the chance to share their triumph with him.
