Adam wants to be a great Scott
Scott defied the persistent rain which soaked the Centenary Course to card a flawless second round 65 for a 12 under halfway of 132.
It gave the Australian a four-shot lead over compatriot Richard Green, who added a 71 to his opening 65, with Ryder Cup captain Sam Torrance a shot further back after a 68 alongside Welshman David Park. Scott's six-shot victory in the Qatar Masters in March - when he led by three at halfway after opening rounds of 67 and 66 - was only his second on the European Tour after a number of near misses, but he intends to get much closer to mentor Greg Norman's total of 14 tour titles before switching his attention to the US tour.
