Paul Casey won by four shots at the Dubai Desert Classic to claim his 15th European Tour title.
The world number 27 led by one stroke heading into the final round and carded a two-under par 70 on Sunday to finish clear of closest challenger Brandon Stone.
European Ryder Cup hopeful Casey was given a scare by Robert MacIntyre, who had a share of the lead at one point, before four successive bogeys put him out of contention.
Casey enjoyed a strong back nine that included a two-putt birdie on the par-five 18th hole to card 271 overall for the tournament.
Stone bogeyed three of his first seven holes but recovered as the day went on to leapfrog MacIntyre into second spot, finishing one shot better off than the Scotsman.
Victory for Casey is his first since the European Open in September 2019. It takes the 43-year-old ahead of Rory McIlroy on the all-time list of European Tour successes, and level with Thomas Bjorn and Padraig Harrington.
"It's very, very special," Casey said. "Dubai has been so good to tour, but to golf around the world as well has been so cool. I've worked so hard.
"I'm hoping for a lot of good stuff for the rest of the season. I feel like I've regained my youth; I mean that sincerely. I'm so happy."
Further down the standings, Laurie Canter finished in a tie with Kalle Samooja for fourth place, while Harrington's final-round 70 saw him share sixth place with Bernd Wiesberger and Sergio Garcia.
