Australian Nick O&aposHern has fired a final round of 66 to finish in third place behind American Hunter Mahan in the Travelers Championship in Connecticut. O&aposHern&aposs round included four birdies over the front nine, but his charge wilted on the tough back nine. Mahan captured his first PGA Tour victory by winning a sudden-death play-off against Jay Williamson. Mahan, who finished second at this event last year, sank a short birdie putt on the first play-off hole to beat Williamson. The victory gave Mahan, who finished the tournament at 15-under-par 265, the first prize of just over one million US dollars. Mahan entered the final round a shot behind Williamson, then took over the lead with three birdies on his first 10 holes. But consecutive bogeys on 16 and 17 put him a stroke behind Williamson, forcing Mahan to make a seven-foot birdie putt on 18 to force the play-off. In the play-off, Mahan hit his approach within 12 inches and Williamson missed his birdie putt from seven feet, giving Mahan the win. Williamson is a member of the Nationwide Tour who attended Trinity College in nearby Hartford. He was playing here on a sponsor&aposs exemption. Vijay Singh of Fiji was fourth, five strokes off the pace. Singh started the first round with a birdie on the first hole and a bogey on the second. He then settled down and finished the round with six birdies to post a five-under 65. Fred Funk was six strokes back for fifth place. Bo Van Pelt, Tom Lehman and David Toms finished in a three-way tie for sixth. England&aposs Justin Rose tied for ninth after a final-round 68, while Australians Steve Allan and Mathew Goggin tied for 15th place at five-under-par. Two shots further adrift was compatriot Peter Lonard, Michael Sim and Rod Pampling tied for 36th at one-under-par, while Andrew Buckle finished in equal 46th place at one-over-par.
