SUN CITY (South Africa) • Alex Noren produced the "round of my life" to card a scintillating 63 for a tournament total of 14-under 274 and a fourth European Tour victory of the season at the Nedbank Challenge yesterday.

The Swede, who started his final round six shots behind overnight leader Wang Jeung Hun, managed eight birdies and an eagle for the lowest round of the tournament as he claimed victory by six shots from the stuttering South Korean.

After a faultless third-round display on Saturday when he carded a 64, Wang was full of nerves and errors and could manage only a 75 to close.

"It's huge," Noren said at the trophy presentation.

"It was one of those rounds, one of those you dream about. It was huge, the round of my life."

Noren, who now moves into the top 10 on golf's world rankings for the first time, is the first Swede to win four European Tour events in a single season after earlier success in the Scottish Open, European Masters and British Masters.

The Race to Dubai will go down to the wire at the season-ending DP World Tour Championship in Dubai next week after money-list leader Henrik Stenson carded a 70 yesterday for an aggregate total of six-under 282 that saw him finish eighth at Sun City.

The Swede is favourite to wrap up the title of Europe's top golfer in 2016 as his nearest rival, England's Danny Willett (69), fell further behind after finishing tied 11th on three-under 285.

At the Lorena Ochoa Invitational in Mexico City, American Austin Ernst seized a one-stroke lead after the third round on Saturday.

The 24-year-old carded a flawless five-under 67 for a 206 total.

Second-round leader Sarah Jane Smith of Australia slipped back with a level-par 72 to end the day in a tie for second with Spaniard Carlota Ciganda (68).

American Angela Stanford (69), Karine Icher of France (70) and South Korean Hur Mi Jung (71) were a further stroke back at 208.
