World No. 2 Rory McIlroy sealed the $2.75 million UBS Hong Kong Open Sunday by holing a birdie chip from a bunker on the last, keeping alive his slim hopes of denying Luke Donald an historic Order of Merit double. A final-round 65 clinched a two-stroke victory for the Northern Irishman and the winner's check for $458,330 means the US Open champion still has a chance of overtaking current Race to Dubai leader Donald with victory at the season-ending Dubai World Championship next week. McIlroy has collected 3,066,605 euros ($4,110,477) for the season to world No. 1-ranked Donald's 3,856,394 euros. The event in Dubai is worth just over 930,000 euros to the winner. Englishman Donald, who has already won the US PGA Tour money list, skipped the Hong Kong event as did Germany's Martin Kaymer, who had been placed second in the Race to Dubai until McIlroy's heroics today. France's Gregory Havret finished in second place on 10-under-par after a storming five-under 65, while Sweden's Peter Hanson was placed third on nine-under after closing with an even-par 70. Quiros faded with a three-over 74 to finish on seven under and joint-seventh. Juvic Pagunsan's six-under for the tournament was enough for 10th place and sealed him the Asian Tour Order of Merit, the first time a player from the Philippines has won the title. Westwood again In South Africa, world No. 3 Lee Westwood of England retained his Nedbank Golf Challenge title Sunday despite shooting a one-over-par 73 in the final round. A record third-round 62 helped him to a 15-under total of 273 — two strokes less than it took Swede Robert Karlsson to cover four rounds over the 7162-meter Gary Player Country Club at this north-west entertainment resort. Karlsson holed a tricky final-green par putt for a 68, the best round of a day when he, Graeme McDowell of Northern Ireland and American Jason Dufner tried in vain to catch the Englishman who led by seven shots overnight. Dufner (69) and McDowell (70) shared third place on 277, Korean Kim Kyung-tae (70) finished on 280 and reigning US Masters champion Charl Schwartzel of South Africa (72) occupied sixth place nine shots adrift of Westwood.
