Veteran Thai golfer Prayad Marksaeng won the Singapore Open by a single stroke on Sunday after the tournament favorite Adam Scott blew his chances of a fourth title by hitting two balls into the water. Prayad shot a final round of four-under-par 67 to finish at nine-under 275 and capture his 20th title since turning professional in 1991, earning himself a place in this year's British Open. "I feel like I have done my country proud," Prayad said. "I am thrilled to earn a spot in The Open too. I hope I can make my country proud again by securing a good result at Royal Birkdale." Four players — Phachara Khongwatmai of Thailand, Juvic Pagunsan of the Philippines, Jbe Kruger of South Africa and the defending champion, South Korea's Song Young-Han — finished tied for second after a thrilling final day where six players had a share of the lead. Phachara, Kruger and Song also secured berths in the British Open but Pagunsan missed out because only four places in total were available and he has the lowest ranking of the runners-up. Kruger leapfrogged him for the last spot when he eagled the final hole. Scott, chasing his fourth victory at the Sentosa Golf Club, led by a stroke heading into the final round but the Australian squandered his chances with a final round of 74 to finish tied for ninth at six-under. Canada's Hadwin fires rare 59 to grab US PGA lead In Los Angeles, Canada's Adam Hadwin became only the eighth golfer to shoot 59 over 18 holes at a US PGA Tour event, sinking 13 birdies in a bogey-free third round Saturday at the CareerBuilder Challenge. The 29-year-old from suburban Vancouver was one stroke off the tour record 58 fired last year by American Jim Furyk at the Travelers Championship. It was the second US PGA Tour 59 in as many weeks, following American Justin Thomas firing 59 on the way to victory in the opening round at last week's Sony Open in Hawaii. Asked to describe the round, Hadwin said, "Perfect, I guess. I got away with a few shots on the back. For whatever reason, I was making every putt I had. "I haven't felt anything like it." Hadwin became only the second player from outside the United States to shoot a 59 in a US PGA event, after Australian Stuart Appleby at the 2010 Greenbrier Classic, and the PGA's first 59-er who has never won a PGA title. Hadwin, who shared 49th when the day began, leaped into the lead at 17-under par 199 for 54 holes, one stroke ahead of American Dominic Bozzelli. Hadwin opened with a 71 and fired a 69 Friday. Hadwin's prior US PGA low round was 63 in the final round of the 2014 Shriners Hospitals Classic in Las Vegas. Crediting playing partner Colt Knost with keeping tensions light, Hadwin said having amateurs alongside as the tournament does also eased the pressure. Bozzelli, like Hadwin seeking his first PGA title, fired a 69 Saturday on the Nicklaus course. "I've been riding a hot putter these last couple days," Bozzelli said. Fleetwood wins Abu Dhabi championship In Abu Dhabi, England's Tommy Fleetwood played superb Golf on the back nine on Sunday to win Abu Dhabi HSBC Championship. The 25-year-old won his second European Tour title three years after winning the 2013 Johnnie Walker Championship at Gleneagles. Fleetwood, ranked 102nd in the world, shot a five-under par 67 to tally 17-under par 271 for the tournament and beat world No. 3 Dustin Johnson (68) and 2014 champion Pablo Larrazabal (68) by one shot. After making the turn at even-par, Fleetwood chipped in for an eagle on the 10th, and then added three more birdies for the biggest win of his career. Three-time champion Martin Kaymer of Germany made an eagle at the last hole to tie Bernd Wiesberger (68) of Austria and Kiradech Aphibarnrat of Thailand (69) in fourth place at 273. — Agencies
