American Peter Uihlein shot four birdies on the back nine to win the Madeira Islands Open by two shots.
Uihlein carded a final-round four-under-par 68 to finish on 15 under for the tournament and see off the challenge of Denmark’s Morten Orum Madsen and Chile’s Mark Tullo, the overnight leader.
Scotland’s Craig Lee finished in fourth place, three shots off the pace, after closing with a 71.
Birdies at the first two holes gave him the ideal start to the final day, but a double bogey and a bogey on the back nine, to go with two birdies, slowed his progress.
Things appeared to be going wrong for Uihlein after back-to-back bogeys at the eighth and ninth dropped him back to level par, but he completed the second half of his round in 32 to recover impressively.
Madsen shot a 67 yesterday and would have forced a play-off had it not been for a double-bogey six at the 18th, which followed eight birdies and a bogey.
Tullo had to settle for a 71, despite a hole-in-one at the par-three fourth.
Wales’ Rhys Davies, and English pair Seve Benson and Richard Bland finished along with Finn Roope Kakko in a four-way tie for fifth on nine under par.
The success was Uihlein’s first as a professional and he could not hide his delight.
“I’m just thrilled,” the 23-year-old said. “To do it playing well on the back nine, coming down the stretch, is sweet.
“I know Morten played a heck of a round and Mark played really well so it was nice to come out on top.
“I just knuckled down I guess. It was all putting that did it today, I was just trying to free up and they started to roll in so it was nice.
“I hit some good putts coming down the stretch. When I was at the 17th I saw Morten was on 15 under and I thought it might have been a little more difficult, but when I got to the 18th green I obviously saw he had dropped back. I’m just delighted to have won.”
Tullo was disappointed not to have emerged victorious after his hole-in-one but said he could take plenty of encouragement from his performance.
“It was a very positive week,” the Chilean said.
“I could have won this tournament. I had three bogeys from 100 yards today which hurt a lot, but hats off to Peter. He played really well on the back nine and that’s what you need to do to win tournaments.
“I didn’t do that, but it was very close and that’s a positive. Maybe there’s something further along the road for me in a big tournament.”
