Bernd Wiesberger was crowned the Shenzhen International champion after beating Tommy Fleetwood in a dramatic play-off at Genzon Golf Club.
The Austrian was in control heading into the final day in China, holding a three-shot lead, but could not have envisaged the kind of performance Fleetwood was to produce.
The Englishman, eight shots behind at the start of his final round, carded an excellent 63 to level with Wiesberger, who could only par the 18th, on 16 under to ensure another trip to the last hole in the rain.
But Wiesberger held his nerve to secure a fourth European Tour victory in his 200th event, putting for birdie despite ending up in the bank after opting to take the risky line over the water off the tee.
The play-off victory was the first for in-form Wiesberger, who has not missed a cut since the US PGA Championship, in four attempts.
He told Sky Sports: "I knew it was going to be hard, I knew I would have to shoot well under par to make it outright because the guys behind were all really playing well.
"I just wanted to get off to a good start and show them that I'm up for it and I did, scrapped around a little bit, had a couple of near misses with good looks at it early on. It could have got to me but I stayed calm, played on decently.
"I had a big save on 12 there, a big one on 17 and I'm feeling a bit relieved now I have to say. I've had a stretch of really good events the last couple of months and it's really nice to have a trophy again.
"We have really good players out here, all up for it, playing well and throwing a lot at me. At the end of the day I'm just glad I got myself into the spot where I could play for the title. Tommy has had a great day today and I'm just grateful to make that one shot when I needed to."
Frenchman Gregory Bourdy and England's Ross Fisher finished one shot behind the co-leaders on 15 under, one ahead of Fabrizio Zanotti, David Lipsky and Dylan Frittelli.
Two-time former Masters champion Bubba Watson fired a final-round two-over par 74 to finish eight under.
England's Florentyna Parker, meanwhile, claimed the third Ladies European Tour title of her career after edging out Anna Nordqvist in a play-off at the Estrella Damm Mediterranean Ladies Open.
Parker shot a five-under final round of 66 as she came from four strokes back to tie with Nordqvist and Carlota Ciganda on 15 under par and force a play-off.
The 27-year-old then birdied the fourth extra hole to take victory after Ciganda had been eliminated at the first hole.
"I knew I had to win. I know I'm not going to get picked for The Solheim Cup, so I know I have to qualify automatically. I think today I've proved that I can play against the best and best them, so I'm really happy," Parker told ladieseuropeantour.com.
"I can't remember how many times I played the 18th hole but I think I had a few birdies today, so it was fantastic and I still can't believe it.
"You're up against the best players in the world, they come over from the LPGA and it's so good to beat them! I was putting quite well towards the end and I knew that green off by heart, so I knew it was going to go in. Luckily, she missed!"
