SEOUL - Park Jun-Won scored a flawless five-under-par 67 Sunday to win the $1 million GS Caltex Maekyung Open by three shots and claim his first professional victory . The 27-year-old had shared the third-round lead with Park Sang-Hyun, but eased away on the back nine to finish the tournament on 15 under par. Lee Ki-Sang (67) and Hwang Jung-Gon (71) shared third place at nine under par, while Australian Scott Hend (72) was the best of the non-Koreans with a share of fifth at seven under. Park only joined OneAsia the day before the tournament started. His previous best finish was joint second at their PGA Championship two years ago. But he played like a veteran all week, shooting a tournament-low 64 in the second round and matching the day's best despite the pressure on Sunday.–AFP
