Bernd Wiesberger cruised to his first career European Tour title as he won the Ballantine's Championship in Icheon, South Korea by five shots from Scotland's Richie Ramsay.
Ramsay had the best round of any of the leaders with a seven-under 65 catapulting him up to second place, but it was not enough to catch Wiesberger who comfortably breezed home, enjoying birdies on three of the last four holes, including the 18th.
Wiesberger had begun the day with a five-shot advantage and never looked troubled
as he focused on keeping mistakes to a minimum.
"I just tried to enjoy it and I had the three best rounds of my life," said Wiesberger on europeantour.com. "I tried not to make bogeys and I did that pretty well, it was awesome.
"My game plan was to hit as many greens as possible and try to make putts, and they dropped in the end.
"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."
The 26-year-old did not drop a shot over his final 59 holes in the tournament.
Ramsay had a blemish-free round, with seven birdies lifting him five places to second, two shots clear of Frenchman Victor Dubuisson, who fired a 66 to move up to third alongside Australian Marcus Fraser, who needed a birdie on the 18th to salvage a round of 70 following a bogey on the previous hole.
England's Anthony Wall had a final round of 67 to move into a tie for fifth alongside Miguel Angel Jimenez.
Ross Fisher had struggled for most of the week here, but a closing round of 66 - four shots better than anything else he had managed in the tournament - moved him up 17 places into a share of seventh alongside Paul McGinley, Alexander Noren, George Coetzee and Felipe Aguilar.
