Anthony Kim became the youngest winner on the PGA Tour in more than six years when he clinched an emphatic five-stroke victory at the $6.4 million Wachovia Championship on Sunday.

The 22-year-old Kim, who started the final round with a four-shot lead, was never headed, picking up four birdies on the front nine en route to a three-under-par 69 in pleasant conditions at Quail Hollow.

"This has been a dream of mine for a long time and I'm living it," he told reporters after finishing at 16-under 272.

Fellow American Ben Curtis shot the day's best score, a 65, to finish second on 11 under.

Kim recorded a tournament record low score and the largest margin of victory in the event's brief six-year history, collecting $1,152,000 and vaulting to sixth on this year's PGA Tour money list.

Born in California of American parents, Kim is aged 22 years and 10 months. The last player to win at a younger age was Sergio Garcia, who won four times on tour before he turned 22.
