Australia's Adam Scott tees off on the 11th hole during the second round of the WGC Bridgestone Invitational PGA golf tournament in Akron, Ohio, Friday. — Reuters AKRON, Ohio – Australian Adam Scott edged one stroke clear of a congested third-round leaderboard at the WGC-Bridgestone Invitational Saturday after a thrilling day of dazzling shot-making and low scoring. While Tiger Woods was among those who failed to take advantage of surprisingly calm conditions at Firestone Country Club, Scott birdied four of his last seven holes for a sparkling four-under-par 66. That left the 31-year-old Scott, who has Woods' former caddie Steve Williams on his bag, at 12-under 198 with compatriot Jason Day (66) and Japanese teenager Ryo Ishikawa (64) tied for second. American PGA Tour rookie Keegan Bradley, one of six players tied for the lead late in the third round, carded a 68 to finish at 10 under alongside Britain's Martin Laird (67). British world No. 1 Luke Donald was among a group of three at nine-under after an improved putting display helped him to a 64 but seven-time champion Woods was a distant 13 strokes off the pace after struggling to a 72. Scott, Ishikawa, Day, Bradley, Laird and Swede Fredrik Jacobson were tied at the top late on before the Japanese edged a stroke clear when he sank a five-foot birdie putt at the 17th. NZ, Singapore, Korea qualify In Petaling Jaya, Malaysia, New Zealand powered to a superb closing round of 67 Saturday to qualify for the Omega Mission Hills World Cup, with Singapore and Korea also securing their place alongside the elite. Taylor takes one-shot lead In Los Angeles, former champion Vaughn Taylor fired a bogey free six-under-par 66 at the Reno-Tahoe Open Friday to take a one-shot lead after the second round. American Taylor holed a bunker shot on the first and eagled the par-five 13th hole to lead at the halfway stage on 135, nine-under, just ahead of compatriot Will Mackenzie (69). MacKenzie, the 2006 winner, was alone in second a shot ahead of fellow Americans Hunter Haas (67), Steve Flesch (69) and Australian first round leader Nick O'Hern, who shot a level par round of 72.
