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 Holland.
But he dropped two shots on the 12th hole and Wu took advantage to claim victory by a single stroke on 16 under par.
The Chinese player stormed into a one-shot clubhouse lead with gains at the 14th, 15th and the last for a final round of 67.
Padraig Harrington finished with a strong three-under 68 to end a good tournament three shots of the winner.
He started his final round three behind leader Wood and rattled in six birdies but three bogeys dented his charge and the three-time major winner had to settle for fifth.
