WHITE SULPHUR SPRINGS - Rookie Ted Potter jnr drained a four-foot birdie at the third hole of a sudden death playoff on Sunday to edge Troy Kelly for a first USPGA tour win at the Greenbrier Classic. Potter, ranked 218th in the world, finished eagle-birdie as he erased a four-shot deficit in regulation, carding a final-round 64 to join Kelly on 16-under 264.He became the sixth first-time winner on the tour this season. He earned a winner's prize of $1,098,000 and jumped from 173rd to 51st in the FedEx Cup playoff standings. It was quite a turnaround for the 28-year-old left-hander, who had missed five straight cuts coming into the tournaments."When you're missing cuts every week, you get down on yourself," Potter acknowledged. "I mean, it's hard to pick yourself back up. But the plus side for me is I was still young. I just knew I had plenty of time and just be patient and it will come back around again."Potter said the two-year tour exemption that goes with the win "was just a big relief ... knowing that now I've got a couple years to try to improve on my game and win some more tournaments." Kelly, who started the day two shots behind overnight leader Webb Simpson, had five birdies in his four-under 66 on the Old White TPC course.Simpson, who claimed a first major title with his US Open triumph at The Olympic Club in San Francisco last month, surrendered a one-shot lead on the back nine of the final round here for the second straight year. Four bogeys in five holes from the 12th spelled the end of his challenge and he closed with a 73 that left him tied for seventh.
