(CNN) -- Austria's Bernd Wiesberger has won his first European Tour title with a commanding final day performance at the Ballantine's Championship in South Korea.
The 26-year-old fired a four-under par round of 68 on Sunday to finish on 18-under par, five shots clear of Scotland's Richie Ramsey who shot a final round 65.
Weisberger, a twice runner-up on the European Tour last season, played the last 59 holes at the Blackstone Golf Club in Seoul without dropping a shot.
Two birdies in the closing three holes on Sunday capped a brilliant week for the Austrian.
"I just tried to enjoy it and I had the three best rounds of my life. I tried not to make bogeys and I did that pretty well, it was awesome," Weisberger said.
"My game plan was to hit as many greens as possible and try to make putts, and they dropped in the end," he added,
"I didn't get nervous, I had three or four shots. There was a pretty shaky moment at 12 but I made a great chip and a putt for par, but I just tried to enjoy it the last three or four holes in."
France's Victor Dubuisson who shot a final round 66 and Australia's Marcus Fraser shared third place, with England's Anthony Wall and Spain's Miguel Angel Jimenez finishing joint fourth on 10-under par.
Australia's Adam Scott produced a fine round of 65 to tie for 12th place ahead of Ian Poulter, who failed to fire in the final round.
The Englishman posted a two-under par round of 70 to finish the tournament on seven-under par tied for 15th place along with a clutch of players including local favorite Y.E. Yang who also posted a final round of 70.
Meanwhile at the Zurich Classic in New Orleans, Jason Dufner is still on course to claim his first PGA Tour title.
The American's third round 67 leaves him on 17-under par, two shots clear of Canada's Graham DeLaet and three clear of America's John Rollins (69) and South Africa's Ernie Els (68).
Dufner, who was tied for the halfway lead at the Masters earlier this month and lost in a playoff to Keegan Bradley at last year's U.S.PGA Championship, isn't thinking about victory yet though.
"For me, it means instead of two good rounds I've had three good rounds, so maybe we can make it four, starting tomorrow," Dufner said, PGATour reported.
"I don't really think about all that type of stuff. Obviously, I know that I hadn't played as well as I would like on the weekends, try to identify some of the reasons why and try to implement some of those tomorrow," Dufner added.
A tightly packed leaderboard with some big names means that Dufner, who hasn't won in 163 starts on Tour, will have his work cut out.
Four shots off the lead are a trio of Americans -- Ryan Palmer, Steve Stricker and Cameron Tringale.
One shot further back is England's Luke Donald, who will regain the world No.1 spot from Northern Ireland's Rory McIlroy if he finishes seventh or better.
Masters champion Bubba Watson, who is playing his first tournament since clinching the Green Jacket, produced a sparkling round of 65 to move up into a tie for 16th place on nine-under par after two opening rounds of 71.
