A long birdie putt on the final hole gave Northern Ireland's Darren Clarke a one-shot victory in the Asian Open on Sunday and his first title in five years. The putt – estimated at 20-30 feet – came in contrast to the dramatic closing stages of the final round when Clarke missed a series of far easier putts to fall back into a tie with Robert-Jan Derksen of the Netherlands, who himself had appeared to blow his chances on the 14th with an errant chip that went across the green and into the water. Clarke and Derksen both shot 1-over 73s in the final round of the jointly sanctioned European Tour and Asian Tour event at the Tomson Shanghai Pudong course to maintain the first and second placings they held after three rounds. Clarke's four-round total was 8-under 280, a stroke ahead of Derksen. England's Robert Dinwiddie had a 2-over 74 to also hold onto third place, sharing it with Italy's Francesco Molinari (69) and Taiwan's Lin Wentang (72) at 5-under 283. The former world's No. 1 Greg Norman of Australia finished with a 1-under 71, only eight shots off the winning score.Scott surges three strokes In Texas, Australia's Adam Scott extended his lead at the Byron Nelson Championship to three shots on Saturday to stand on the verge of a first PGA Tour victory in more than a year. The world number 10 began the third round with a one-shot cushion and was able to stretch his advantage by a further two strokes after firing a three-under par 67, moving to eight under for the tournament. The Australian capitalized on two sublime chip shots to birdie the par-five 16th and par-four closing hole as he ended his round with a flourish. A quartet of Americans – Bart Bryant, Kevin Sutherland, Charley Hoffman and Ryan Moore – are Scott's closest pursuers on five-under 205 for the tournament. Sergio Garcia (65) is tied for sixth, four shots behind Scott, as he seeks a first top-10 finish of the year.Sorenstam seizes lead In Miami, Annika Sorenstam, seeking her second LPGA victory of the season, fired a one-under par 70 Saturday to seize a one-stroke lead after the third round of the two million-dollar Stanford International. Swedish former world number one Sorenstam stood on seven-under par 205 after 54 holes but American Paula Creamer dropped an eight-foot birdie putt at the par-five 18th to finish a round of 67 and move one back of the leader. Japan's Momoko Ueda and South Korean Young Kim shared third on 207, one stroke ahead of American Cristie Kerr and two ahead of Dorothy Delasin.
