Gonzalo Fernandez-Castano claimed his seventh European Tour title on Sunday with victory in the BMW Masters in Shanghai, despite a messy finish to his final round.
Fernandez-Castano was three shots clear of the field with one hole to play, but ran up a double-bogey six on the 18th to mar an otherwise brilliant performance.
The Spaniard began the day one shot behind joint leaders Luke Guthrie and Rafael Cabrera-Bello but carded a closing 68 to finish 11 under par at Lake Malaren, one shot ahead of Seve Trophy team-mate Francesco Molinari and Thailand's Thongchai Jaidee.
Shane Lowry was best of the Irish after a final round of 67 left him two under with Padraig Harrington and Rory McIlroy on one under after 73s. Paul McGinley finished three over, while Graeme McDowell finished six over.
At the start of the day Molinari was six shots off the pace and despite a front nine of 34, his chances looked to have disappeared with a bogey on the 12th.
However, the Ryder Cup star then went on a brilliant scoring run, making an eagle on the par-five 13th and following that with four birdies in succession to join Fernandez-Castano on 10 under before eventually completing a superb 64.
Fernandez-Castano edged back into the lead with a birdie on the 13th and looked to have sealed a comfortable win with further birdies at the 15th and 17th, where he chipped in from just over the green.
He made hard work of the last, though, finding sand off the tee and another bunker with his third shot before holding his nerve to complete his first victory since last year's Italian Open.
Guthrie finished two shots behind on nine under after a closing 71, with Thomas Bjorn, Peter Uihlein and Pablo Larrazabal a shot further back.
Defending champion Peter Hanson finished seven under after a superb closing 63, the Swede having started the tournament - which does not have a halfway cut - with a round of 79.
"I knew it wasn't going to be an easy round, especially the way I started. I started hitting the ball pretty bad," Fernandez-Castano told Sky Sports 2. "But my caddie kept me cool and told me how good I had been hitting the ball through the week and I played fantastic after that.
"On the last I played too conservative and it was a fighting six at the end for sure."
Meanwhile, Hanson, after a round containing 11 birdies and two bogeys, joked: "I was playing with Paul McGinley, the Ryder Cup captain, and I guess I wanted to impress him.
"I had no expectations on coming back from injury and I was obviously very rusty on Thursday.
“But I have felt better and better throughout the week and to finish with a round like that is very pleasing. As a defence, it wasn't bad!"
