Close fight for Wales Open crown
Joost Luiten and Thongchai Jaidee were tied for the lead after six holes of the final round in the ISPS Handa Open at Celtic Manor.
England's Ross Fisher moved alongside overnight leader Jaidee when he chipped to a foot on the long second, but the former Ryder Cup player bogeyed the fourth and three-putted the sixth for another dropped shot.
Jaidee also bogeyed the fourth after bunkering his approach, while Luiten reeled off six pars in a row.
Fisher was then joined in third place only one behind on five under par when Dane Thomas Bjorn turned in a three-under 33.
Jaidee was back in front on his own when Luiten bogeyed the short seventh, but it all changed on the 580-yard ninth when Luiten birdied and Jaidee lost a ball and ran up a double-bogey seven.
That left Luiten six under again and one in front of Fisher, Bjorn and Sjoholm, while 45-year-old Paul McGinley set the clubhouse target on four under after a brilliant 65 in the miserable conditions.
Jaidee hit back with two birdies and when Fisher also made a four on the long 11th it was a three-way tie - but only for a few moments as Luiten two-putted from the fringe for a matching birdie there.
He could not get up and down from sand at the next, however, and with Bjorn two-putting the driveable 15th for birdie four players were level on six under.
Jaidee then converted his 10-foot chance for a third successive birdie on the difficult 12th - only the third there all day - and moved back in front.
McGinley's slim hopes ended when Spain's Gonzalo Fernandez-Castano shot 67 for five under.
Jaidee remained seven under with five to play, one ahead of Fisher and Luiten after Bjorn bogeyed the short 17th as the rain lashed down again.
Fisher appeared to have remained one behind with a par on the 14th, but it turned into a bogey because of a one-stroke slow-play penalty.
European Tour chief referee John Paramor had been following the final group for several holes and Fisher had incurred his first bad time on the long 11th.
Jaidee then made an 18-foot birdie putt on the next and with that moved into a two-shot lead over Luiten.
