Tournament host Tiger Woods saw off defending champion Anthony Kim and held off a last-round charge from Hunter Mahan to win the AT&T National at Congressional Country Club, while Australian Rod Pampling crashed out of contention. Starting the day two shots behind Woods, Pampling never threatened as he posted five bogeys in his first seven holes on his way to a five-over 75, which saw him tumble down a tie for 20th. Stuart Appleby was the best placed Australian in a tie for 16th at four-under, while Nick O&aposHern, Steve Elkington, Aaron Baddeley and March Leishman all finished in a share of 25th. Woods collected his third victory of the year, having won Arnold Palmer&aposs event at Bay Hill in March and Jack Nicklaus&apos Memorial last month, by winning his own tournament by one stroke from Mahan with a final-round three-under-par 67. It was also his 68th PGA Tour win and the 79th worldwide victory of his career. Mahan had earlier shot a 62 that matched Kim&aposs course-record round from Thursday and took the American to 12-under, but Woods moved in front with a birdie at the 16th and held onto his lead down the final stretch. The world No.1 had been paired with Kim in the final group in Bethesda, Maryland, one-shot leaders at 10-under-par over fellow Americans Michael Allen and Cameron Beckman. Kim got off to a fast start with a birdie at the par-four first hole but had returned to 10-under with a bogey at the fifth, another par four, before Woods took control with back-to-back birdies at the par-four sixth and par-three seventh. Kim appeared to be blowing his childhood dream of sharing the spotlight in contention with Woods when he bogeyed the eighth to fall three shots back of the 14-time major winner. Both men sent down birdies, Kim at the ninth, Woods at the 10th but the 24-year-old defending champion was given a lifeline when his hero sent down a bogey five at the 11th, the hole that has been his nemesis on the par-70 Blue Course near Washington DC this week following two bogeys and a double there in previous rounds. The 16th proved critical as Kim&aposs chance of a successful defence disappeared as he missed from eight feet for birdie while Woods did birdie. Woods finished at 13-under, a shot ahead of Mahan with Kim, having shot a 71 to finish third on nine-under-par. Bryce Molder finished in fourth place on eight under with US Open champion Lucas Glover, level for the day, and Brandt Snedeker, who shot a 67, tied for fifth at seven under. Vijay Singh had earlier shown that low scoring was possible with six birdies in his first 13 holes before two bogeys left the Fijian with a 66 to finish at six-under for the tournament, tied for seventh with New Zealand rookie Danny Lee and Americans Jim Furyk and Cameron Beckman. Meanwhile, on the European Tour, Australian Richard Green carded an even-par final round to finish in a tie for sixth place at the French Open, with compatriot Scott Strange a further stroke back at seven-under in a share of 10th. German Martin Kaymer won the tournament in a play-off after he and Englishman Lee Westwood finished equal on 13-under.
