Chris Wood paid the price for a double bogey on the back nine as Wu Ashun held his nerve to win the KLM Open.
Wood, who took a one-shot lead into the final round, was on course for a fourth European Tour title after opening up a three-stroke advantage in Spijk.
But he dropped two shots on the 12th hole and Wu took advantage to claim victory by a single stroke on 16 under par.
Wu finished three strokes clear of Pádraig Harrington, who secured fifth spot with a closing round of 68.
Harrington made six birdies but dropped three shots on Sunday as he couldn’t ignite a serious title challenge - the three-time Major winner finishing on 13 under par for the tournament.
“I am so happy,” winner Wu told Sky Sports Golf.
“It was beautiful weather this week too and a lot of good golf played here and I like this golf course very much.
“We fixed my swing at the beginning of the year and we still trust that we are going the right way.
“My coach and me are working very hard and he has flown to Czech Republic and Denmark to help me so I think we are getting better and better; so that’s why I think last week was top 10 (in Switzerland) and then this week just win.
“I was happy to have my name on it.”
Wood clawed a shot back with a birdie at the 13th, only for Wu to storm into a one-stroke clubhouse lead with gains at the 14th, 15th and the last for a final round of 67.
That meant the Englishman needed a birdie at the par-five 18th to force a play-off, and it looked like he could snatch victory as he reached the green in two.
However, Wood raced his eagle putt past the hole and onto the fringe and his second attempt missed the left edge of the cup to hand Wu his third European Tour victory.
Japan’s Hideto Tanihara and Belgium’s Thomas Detry finished tied for third on 14 under par, with three-time major champion Padraig Harrington one shot further adrift to round off the top five.
