SUN CITY, South Africa: World No. 1 Lee Westwood gave a golfing masterclass to sprint three shots clear of the field after the Sun City Challenge second round Friday. The 37-year-old Briton fired an eight-under-par 64, with four birdies on each nine and no bogeys, to finish on 12-under 132 at the Gary Player Country Club. Westwood ended his round with a flourish as another immaculate approach shot to the 18th left him with a 12-foot birdie putt which he sank. Fellow Englishman and Ryder Cup teammate Ross Fisher carded a 68 to take second spot on 135. Overnight leader Padraig Harrington, another member of Europe's triumphant Ryder Cup side, could only manage a 72 as he wound up six strokes off the pace. Edoardo Molinari, who also featured in the Ryder Cup win in October, claimed eagle threes at the second and 10th to climb into contention. The Italian, though, could only add one birdie as he finished with a 67 for 138 and a tie for third place with Harrington and Ryder Cup stalwart Miguel Angel Jimenez (69) of Spain. Triple champion Ernie Els was sixth on 139 after a 68 while holder Robert Allenby of Australia was joint seventh on 140 with South African Tim Clark. Ogilvy ahead Geoff Ogilvy shot a seven-under-par 65 at The Lakes course Friday to take a one-stroke lead after two rounds at the Australian Open. Ogilvy, the 2006 US Open champion, had a 36-hole total of 11-under par 133. Australian Matt Jones shot 64 to sit one stroke back of Ogilvy, with first-round leader Matthew Griffin, also from Australia, another stroke back after a 70. American Dudley Hart, making his first tournament start in 18 months following back surgery, shot 69 and was tied for fourth with Australians John Senden (71) and Paul Sheehan (67). Ogilvy won the US PGA Tour's season-opening event in Hawaii before having a difficult year and falling to 43rd in the world rankings. “You're lying if you said you're not thinking about winning, but it's way in the back of your mind,” Ogilvy said. “The closer you get to the end the more you start thinking about it, but after 36 holes it's not going to monopolize my thoughts.” Playing partner Adam Scott also took advantage of some easy morning conditions – not much wind and slow, soft greens due to recent rain – to shoot 66. Scott, the defending champion, shot 75 Thursday. Baek, Griffiths share lead Korean youngster Baek Seuk-hyun and England's Simon Griffiths, each seeking to win their maiden Asian Tour title, shared the halfway lead in the 1.25-million-dollar Hero Honda Indian Open at DelhiFriday. The 20-year-old Baek, who has lived in Thailand for the past eight years, stunned even his father with a second-round two-under-par 70 to tie Griffiths, who fired a superb 67, on six-under-par 138 at the Delhi Golf Club. A shot back was India's Manav Jaini (69), American duo Anthony Kang (67) and rookie Ben Fox (69) and Sweden's Rikard Karlberg (69).
