Briton Graeme McDowell moved into a share of the lead at the Chevron World Challenge Saturday after being named as a late replacement in the field due the absence of world No. 1 Tiger Woods. Woods withdrew from the event, which he hosts, citing undisclosed injuries following a car crash last week. McDowell shot a third-round six-under 66 and is tied with South Korea's Y.E Yang at 10-under par 206. Ireland's Padraig Harrington and Britain's Lee Westwood are one stroke behind. McDowell was playing in the World Cup in China last week when he was met by his manager, who told him that he might be taking Woods' place at the event. McDowell took advantage of the back nine, making four birdies and an eagle from holes 10 to 15. His eagle putt on 15 was a curling 60-footer that dropped into the hole. His only mistake of the round was a big one, making double bogey on the 563-yard par-five 16th hole. McDowell's tee shot found a fairway hazard and his next shot went into a water hazard. Yang had been the second-round leader by two strokes, but is still suffering from flu-like symptoms and shot a one-under-par 71 as he struggled throughout his round. Harrington, who has won the event in 2002, was disappointed that he was a stroke behind the leaders after he finished with two-under 70 Saturday. Scott wins Australian Open Australia's Adam Scott broke through for his first victory at home with a five-shot win in the OneAsia Tour-sanctioned Australian Open Sunday. Scott only needed a closing par round of 72 to hold off compatriot Stuart Appleby and claim the Open with a four-round total of 15-under 273 at the New South Wales Golf Club in Sydney's south. Since turning professional in 2000, Scott, 29, has repeatedly failed to win in Australia, but he was in no danger over Sunday's final 18 holes holding a comfortable buffer against Appleby. Appleby carded a three-over 75 to finish the tournament at 10-under 278. Scott won the Byron Nelson Championship in April last year, his sixth US Tour triumph and 14th overall, and Sunday's trophy ends a 20-month dry spell. Having dived to number 54 on the world rankings, Scott will now find himself back in the top 50 when the latest list is released this week after his Australian Open triumph. American Bryce Molder, New Zealander Michael Long and Australian Nick O'Hern finished nine strokes behind Scott in joint third place. American two-time major winner John Daly capped his solid tournament with a final round 71 to finish the week at two-over par 290 and in a tie for 28th place.
