Erik van Rooyen birdied the final hole to win his first European Tour title at the Scandinavian Invitation on Sunday.
The South African carded a six-under 64 in the final round at Hills Golf & Sports Club to finish 19 under and a shot ahead of England's Matt Fitzpatrick (64).
South Australian Wade Ormsby, who was just one shot back heading into the final round, finished tied for fifth place after a final-round 69 to finish on 13 under for the tournament.
"I was so nervous on 18," Van Rooyen said. "I've been putting so well all day and to hole that one to win, it's my first one, it's pretty cool."
Home favourite Henrik Stenson, who held a share of the lead after making a hole-in-one on the 6th, finished in a tie for third with Dean Burmester of South Africa after both men shot 66.
Van Rooyen looked to be in control after six birdies in his first 13 holes, but bogied the 17th after Fitzpatrick birdied the same hole.
Fitzpatrick also birdied the last to draw level on 18 under but Van Rooyen held his nerve to birdie the last for the fourth day running, holing from 12 feet for the win.
