Robert Allenby has been pipped on the line by rookie American Dustin Johnson as four Australians claimed top-10 positions at the Turning Stone Resort Championship. Allenby, seeking his fifth victory and first since 2001, was denied when his 12-foot last-gasp putt for a birdie to tie with Johnson stopped just short. Allenby posted a two-under 70 in the final round but did not record a birdie on the back nine. He bogeyed No.15, which ultimately led to his demise. Starting the day two shots off the lead, Allenby played his first nine holes at three-under to move to nine-under overall. The Australian registered birdies at Nos. two, three and five but could not finish it off. “Yeah, I&aposm disappointed,” Allenby said. “I hit some putts that could have gone in. I mean, the greens are pretty bumpy, and it&aposs really hard. The thing is, when you&aposre putting on greens like this, it&aposs so hard to commit to hit like a foot, two feet past the hole.” Johnson, meanwhile, charged past a pack of likely last-round contenders to claim his first career win on the PGA Tour with a nine-under total. He got the better of six other players – including Aussie youngster Jason Day – who all began the final round hoping to record the first tour title of their careers. Instead, Johnson sunk an eight-foot birdie putt on the final hole at Verona, near New York, to edge out veteran Allenby by one shot. “Hasn&apost quite sunk in yet, so I don&apost really quite know what&aposs going on yet,” Johnson said. “Obviously, it&aposs a great feeling. I feel like I&aposve worked real hard the last month to get my game in shape to be in the position to win a tournament, so I&aposm very excited.” Home hopes Tag Ridings, Kyle Thompson and Jeff Overton and Day were among those who just ran out of steam. Day, who started the day tied for third, could only manage a three-over 75 to fall back to four-under for the tournament in a share of 19th spot. Mathew Goggin and Steve Allan finished in equal third place at seven-under alongside Japan&aposs Ryuji Imada and Americans Woody Austin, Robert Garrigus, Davis Love III and Charles Howell III. Nick O&aposHern took a share of 10th place one stroke further back after a closing four-under 68 saw him jump up to six-under. Of the other Australians in the field, Steve Elkington and Mark Hensby were equal 15th at five-under, John Senden (70) finished in a tie for 27th, while Nathan Green and Kiwi Tim Wilkinson took a share of 36th spot.
