Englishman Paul Waring held off Tyrell Hatton and Rory McIlroy to win the Abu Dhabi HSBC Championship by two strokes on Sunday.
The 39-year-old had taken control of the event with a course-record 61 at Yas Links on Friday but saw his five-shot halfway lead reduced to one as he posted a 73 a day later.
Waring had spoken of feeling jittery during his third round but he displayed nerves of steel in a flawless closing 66.
Race to Dubai leader Rory McIlroy, four-time Rolex Series winner Tyrrell Hatton and former Open Champion Shane Lowry were among those to turn up the heat on Waring during a thrilling final round.
But Waring, whose only previous DP World Tour title came at the Nordea Masters more than six years ago, responded to being caught by Hatton with a birdie from 40 feet at the 17th and played the last impeccably to claim the $1,530,000 winner's cheque.
"It just means so much to so many other things that come with that win," said Waring, who climbs to fifth in the Race to Dubai Rankings in Partnership with Rolex to put himself firmly on course to claim one of the ten PGA TOUR cards on offer for 2025.
"That said, early in the week, to actually keep control of myself in the way that I did today I'm really proud of myself, and (caddie) Alex (Evans) was absolutely amazing. Playing partner was amazing, Shane was great as was Niklas (Norgaard). I'm a bit taken aback right now.
"I'm not that emotional on golf courses. I tend not to fist-pump and I tend not to get up and down, and I tend to stay quite steady. It was actually the putt on 15, the par save. It was only five feet but it was such a solid putt. It just gave me so much confidence coming in that if I just keep hitting putts like that I'll be fine.
"The one on 17, I could just see it tracking in the whole way, and just knew I was going to hole it. As soon as it left the blade, I knew it was in. So yeah, it was a big moment. Big, big moment.
"I thought the second shot into 18 was absolutely perfect. To see it go long was, 'right, I've still got business, still got stuff to do'.
"So got my head back on. I'll be honest, legs were shaking a little bit over that last putt. I just wanted to make sure that nothing else could happen and great to roll that one in on the last as well.
"I don't want to sound over the top or anything but I felt like my golf game has been in such a good place over the last year. Just haven't put it all together. And then this week arrives and you know what, a week for it all to come together, putting nicely, approach play was great, great off the tee. It's nice to put it all together and get a tournament like this."
McIlroy was first to make an early charge as the four-time Major winner birdied four of his first six holes.
Waring responded with back-to-back birdies to start his round and produced a superb up-and-down to save par at the fourth – the scene of his three-putt bogey from eight feet on Saturday.
English pair Matthew Jordan and Matt Wallace closed to within one of the lead with eagles at the seventh and 11th respectively but McIlroy missed a short par effort at the seventh and missed from eight feet for birdie two holes later.
Waring was millimetres away from picking up another shot at the sixth but was rewarded for an excellent bunker shot with a gain at the next.
He made another birdie from ten feet at the tenth to keep the chasing pack at bay but missed out on the par-five 11th after driving into a bunker and missed from five feet at the 13th, before lipping out with a 25-foot effort at the next.
By this point playing partner Lowry had emerged as the main threat but the Irishman almost hit his tee shot in the water at the 14th and could only find a bunker with his second before making bogey.
It was Waring's turn to scramble a par after a wayward drive at the 15th, but former winner Hatton birdied the last two to see Waring caught for the first time in two days and set the clubhouse target at 22 under.
Then came Waring's moment of magic as he converted from 40 feet at the 17th, before hitting a perfect drive at the last, running a three-wood through the back of the green and getting up and down to seal victory with a 24-under total.
Hatton took second with his stunning closing 64, with McIlroy, Thorbjørn Olesen and Wallace sharing third on 21 under.
