Wyndham Clark birdied five of his first seven holes and hung on for a one-stroke lead as Fiji veteran Vijay Singh stormed into contention in the third round of the Honda Classic Saturday. American Clark carded a second consecutive three-under 67 to sit atop the leaderboard at PGA National in south Florida at seven-under 203, one ahead of 56-year-old Singh who will bid to become the US PGA Tour's oldest winner Sunday. Sam Snead won the Greater Greensboro Open in 1965 at the age of 52. "It would be great," Singh, who has not won on the tour in 11 years, said of the record. "I'm physically quite capable of doing it. "Mentally, I'm going to go out there and see how my mind works. If I just don't let anything interfere, I think I can do it." Three-time major winner Singh's five-under 65 was the lowest score of the round. He was eventually joined by Keith Mitchell (70) and South Korean Lee Kyoung-hoon (68) on six-under 204. Rickie Fowler was two shots behind Clark on 205 after shooting a 66, with six players another stroke behind including first round leader Jhonattan Vegas (69). Second-round co-leader Im Sung-jae all but crashed out of contention with a seven-over 77 that left him eight strokes off the pace. Clark, seeking his first PGA Tour victory, got off to a sizzling start, but cooled as the 25-year-old suffered bogeys on the ninth, 13th and 15th holes. Mitchell, the second round co-leader with Im, shared the lead with Clark for a major portion of the day, but a bogey at the 16th ended his chances of matching Clark. Adam Schenk, who was among the six players three strokes behind after a 68, was retroactively assessed a two-stroke penalty for a rules violation Friday. Murray wins New Zealand Open win Rising Australian talent Zach Murray held his nerve to complete an end-to-end win in the New Zealand Open at Queenstown Sunday. The 21-year-old rookie fired a final round four-under 68 to finish on 21-under and two strokes clear of fellow Australian Ashley Hall and New Zealand's Josh Geary at the Millbrook Resort course. Geary had his chance when two early birdies gave him a share of the lead. But he followed with four bogeys to drop off the pace before a late eagle and two birdies brought him back up the leader board. Thailand's Jazz Janewattananond had two eagles in his final round of eight under 64 to move up to fourth place on 18 under. One stroke back were Australian Brad Kennedy and Japan's Rikuya Hoshino and Ryuko Tokimatsu who were tied for fifth. — Agencies
