COLOMBO (AFP) - Torrential rain washed away defending champions Australia's World Cup clash with Sri Lanka on Saturday, just as the eagerly awaited encounter between the fierce rivals was coming to the boil. Sri Lanka had made 146-3, with skipper Kumar Sangakkara hitting an unbeaten 73, when Colombo's R. Premadasa stadium, packed with 35,000 fans, was swamped by a downpour. After a delay of two-and-a-half hours, play was abandoned as a no result with both sides awarded a point apiece. "It's a shame, it was shaping up to be a terrific game. Sangakkara was controlling the match for them," said Australia skipper Ricky Ponting. "It would have been a tough wicket to bat on second it would have been a tough run chase."
