Kristoffer Broberg won the BMW Masters in China following a play-off victory over Patrick Reed.
The Swede came into the final round two shots off the lead, but turned in 33 to hold a share of top spot and a single birdie on the back nine got him to 17 under.
Playing partner Reed picked up four shots in four holes from the 13th, including a spectacular eagle on the 15th, to take a one shot lead onto the 17th tee. But he dropped a shot on the 17th, and the leading duo parred the last to send the tournament to a play-off up the 18th.
Reed put his second shot into the bunker, and although he played an excellent recovery for par, he could only watch on as Broberg rolled in a 15-foot putt down the hill to add his first European Tour title to his four Challenge Tour triumphs.
Thongchai Jaidee had begun the day with a one shot lead and he had a putt on the last to force his way into the play-off, as did Byeong-hun An, but both men had to settle for a share of third at 16 under alongside Lucas Bjerregaard and Henrik Stenson.
Justin Rose was then a further shot back alongside Paul Casey with Julien Quesne and Søren Kjeldsen, who shot a low round of the day 64, at 14 under.
With Race to Dubai leader Rory McIlroy not present in Shanghai, the week presented an opportunity for some of the chasing pack to overtake the Northern Irishman heading into the season-ending DP World Tour Championship in Dubai.
But none of them could, with closest rival Danny Willett finishing in a tie for 28th at seven under and closing the gap to just 1,613 points.
