Nicolai Hojgaard has produced a brilliant eight-under-par 64 on the final day to claim victory at the season-ending DP World Tour Championship in Dubai.
The 22-year-old Dane recorded nine birdies - including six on a scintillating back nine - and only one bogey on Sunday to finish two shots clear of his Ryder Cup teammates Viktor Hovland and Tommy Fleetwood, and overnight leader Matt Wallace.
Ryder Cup star Hojgaard saw off the challenge of his rivals with a stunning run of five successive birdies from the 13th to finish on 21 under at the Greg Norman-designed Earth Course at Jumeirah Golf Estates.
Hojgaard described the win as the greatest in his career, while dedicating it to his family.
"It means a lot, it's the sweetest one," he said.
"So much hard work has been put in over the past couple years. It feels amazing, this is for family and everything they put in over the years. So much hard work going into this, for it to happen like this is unbelievable.
"We know there are a lot of birdies but we have to hit the shots and hole the putts, anything can happen we were just focused on the job today, to walk up 18 knowing there's a good chance feels good.
"I played some really good golf. I have to say this is the best golf I've played in a tournament and the strongest field in my three wins. My game feels good, I felt good before going out and to finish it like this feels good.
"This is the sweetest way to finish the year, I cant believe we finished on such a high note, I'm definitely going to enjoy this."
England's Wallace started the final day with a one-shot lead over Fleetwood and Hovland after a remarkable third round of 60 but he could only card a 69 on Sunday and had to settle for a share of second spot.
Countryman Fleetwood finished off with a 68, as did Norway's Hovland. Defending champion Jon Rahm (66) was tied for fifth at 17 under, with world No.2 Rory McIlroy seven shots back after a 70.
Australian Min Woo Lee ended up tied for 15th on 13 under after a final round of 69, while his compatriot Lucas Herbert also finished with a 69 to end up in joint 38th position at four under.
