The 18-year-old floated a superb chip shot from behind a hospitality marquee to within four feet as his four-under-par 68 edged out compatriot KJ Choi, who closed with a 69.

Noh finished with a winning total of 14-under 274 in Kuala Lumpur as the joint overnight leaders, Thai Kiradech Aphibarnrat and Britain's Rhys Davies, slipped back with 71s.

"It was a good up-and-down," Noh said of his finish at the 18th. "This week I've had three or four chip-ins for birdies and I also chipped it in today on number one.

"That kind of gave me a good vibe so I was able to close it out," added Noh, who has now secured Tour cards in Japan, Asia and Europe after winning the $2 million co-sanctioned Asian and European Tour event.

Noh stepped on to the final tee with a one-stroke lead but hooked his drive badly before hitting his second shot on to the cart path running along the practice putting green.

With Choi having just birdied the 18th, Noh calmly chipped over a greenside bunker to leave himself a short putt for victory.

Denmark's Soren Hansen shot a 70 for a share of third with Kiradech and Davies, while Thailand's Thongchai Jaidee, who began the final round one off the lead, fell away with an even-par 72.

Sunday's final round belonged to Noh, whose father caddied for him during the tournament at Kuala Lumpur Golf and Country Club.

In Gold Coast, Australia, Australian Karrie Webb fired an 11-under par closing round of 61 to capture her seventh Australian Ladies Masters title by six shots at Royal Pines here on Sunday.

The 35-year-old former world No. 1 left one of her finest rounds to the end to run away with the championship from compatriot and defending champion Katherine Hull.

Webb simply gave no one else a chance by carding nine birdies and an eagle to equal her career-lowest round and finish the tournament at 26-under 262.

Webb's round was highlighted by an eagle two at the seventh hole and a 10-meter birdie at the last hole.

Her nine-iron flew 120 meters straight at the flagstick at the seventh and dropped into the hole for an eagle.

Hull (67-70-65-66) and young South Korean Lee Bo-Me (69-70-63-66) finished joint second on 20-under 268.

Hull went birdie for birdie with Webb until the seven-time major winner's class kicked in on the back nine.

She was gracious in defeat: "You can never rule out a hall of fame player, it was just an absolute clinic on Karrie's part," she said.

Hull will get another crack at Webb in next week's Australian Open at Commonwealth Golf Club in Melbourne.

South Korean Seo Hee-Kyung (69-68-66-66) finished fourth on 19-under 269 and compatriot Ryu So-Yeon was fifth on 15-under 273.
 
In Miami, Camilo Villegas emerged from a shaky back nine with a three-stroke lead after shooting a three-under 67 at the third round of The Honda Classic on Saturday.

The in-form Colombian, joint overnight leader with American Anthony Kim, charged out of the blocks with four birdies on the front nine, before stumbling with three bogeys to fall back into the pack at the PGA National Championship course.

Villegas recovered with two birdies, however, to finish with a total of 11-under, three strokes ahead of Fiji's Vijay Singh and Australian Nathan Green.
 
Anthony Kim, who held a one-stroke lead with Villegas overnight, tumbled down the leaderboard with a three-over 73 after a double-bogey on the par-four sixth and three dropped shots from his last three holes.

Villegas, who came third at last month's WGC-Accenture Match Play Championship and tied for eighth at the Phoenix Open that finished Sunday, is chasing his third PGA Tour title after winning back-to-back tournaments in 2008.

The 28-year-old held firm on the course's most difficult holes, taking a birdie on the 488-yard par-four sixth, where Singh and Kim both had double-bogeys.

Villegas negotiated holes 15 through 17, known as the 'Bear Trap', with two pars and a birdie, as Kim stumbled to finish six strokes off the pace.
