NEWPORT, Wales -- Thailand's Thongchai Jaidee survived a poor start on Sunday to win the Wales Open by one stroke with a final-round 1-over 72 in wet conditions.
The 42-year-old Jaidee, who was the overnight leader, holed four birdies on the back nine at Celtic Manor after bogeying the fourth and double-bogeying the par-five ninth, where he went out of bounds before finding a bunker.
"The conditions were really tough today, they were not like Thailand," Jaidee said. "I was pleased to putt well on the back nine."
Jaidee finished with an overall 6-under 278 for his fifth European Tour title.
The Netherlands' Jooist Luiten (72) and Denmark's Thomas Bjorn (68) shared second place with Spain's Gonzalo Fernandez-Castano (67) and South Africa's Richard Sterne (68) at overall 5 under.
Bjorn, ranked 37th in the world, was pleased with his week despite falling short on the final day.
"I thought if I got 66 I'd have a chance," Bjorn said. "Instead, I have left a couple out there but I knew what I had to do."
England's Ross Fisher (73) tied for sixth with Ireland's Paul McGinley (65) at 4-under 280.
Fisher was given a one-shot penalty on No. 14 for time taken over his first putt. Fisher was warned two holes earlier that he would be sanctioned by a shot if he continued to play slowly.
McGinley, who was a vice-captain for Europe's 2010 Ryder Cup victory over the United States, shot a 6-under 65, which was the lowest round of the day.
"I have played well all week, but the scores haven't matched it," McGinley said. "Today, I played as well as I have in my life."
