Julian Suri claimed his maiden European Tour title after seeing off the challenge of David Horsey in a thrilling final round at the Made in Denmark.
American Suri produced a flawless 64 on Sunday to finish the week on 19 under par and secure his first victory in just his seventh European Tour event.
Horsey was one stroke adrift of playing partner Suri as they stood at the 18th tee but finished four shots back in second after carding a disappointing triple bogey at the last.
Suri, who won the D+D REAL Czech Challenge in May, becomes the third American to win on the European Tour and Challenge Tour, following in the footsteps of Brooks Koepka and Peter Uihlein.
Englishmen Ben Evans, Steve Webster and Chris Paisley were in a tie for third on 13 under par.
Suri began the day two shots behind overnight leader Horsey but picked up an early birdie at the second after sending his tee-shot to within three feet of the pin.
The 26 year old then took the outright lead when he curled in from six feet for a birdie at the third before picking up another shot at the fourth to make it three birdies in a row.
And after making another gain at the seventh, Suri knocked in his six-foot birdie putt at the eighth to move to 17 under.
With Suri reeling off five straight pars from the ninth, Horsey joined him at the summit after making back-to-back gains at the 11th and 12th.
And the pair holed similar birdie putts from around 12 feet at the 14th to get to 18 under.
It was a blast out there. Especially in that atmosphere with the fans. It was really cool - Julian Suri
Suri then rolled in a phenomenal putt from around 15 feet at the next to open up a one-shot lead.
And after safely finding the fairway with his tee-shot at the last, Suri finished with a par to lift the trophy.
Suri was thrilled with his final-round performance. He said: "To have seven birdies and be bogey-free in the final round was really solid. I'm pretty proud of that.
"It was a blast out there. Especially in that atmosphere with the fans. It was really cool.
"Everybody is so enthusiastic out there, with such genuine appreciation for the game and spectacle.
"I just wanted to soak it up as much as I could.
"I feel like my game belongs at the top of the game. This is definitely something I've worked for and kind of expected for a long time.
"But to finally come out and do it, especially after the string of good finishes this summer, is really special."
Horsey, who won this event in 2015, opened his fourth round with a bogey but bounced back with birdies at the fourth and seventh.
The four-time European Tour winner knocked in his birdie putt from six feet at the 11th before repeating the trick from 15 feet at the next to get to 17 under and join Suri at the top.
And after watching Suri convert his birdie putt at the 14th, Horsey followed him in from a similar distance to remain in a tie for the lead.
But when he could not match Suri's birdie at the 15th, Horsey dropped into second place.
Horsey's challenge faltered when he got into trouble off the 18th tee and he made a triple-bogey seven to finish on 15 under.
"I wasn't quite firing to start with," said Horsey. "I then made a few birdies going into the back nine and put a bit of pressure on him.
"It was a great battle to be honest. He played very well and thoroughly deserved the victory.
"When someone's playing well and you don't really expect them to make mistakes, you know you've got to make birdies and it really helps you focus on what you've got to do.
"It's just a shame I couldn't quite put enough pressure on him up the last.
"My game's coming on. I've been doing a lot of work over the last three or four months and it's really starting to take effect."
