Little-known Jeppe Huldahl ensured there was a third shock win on the European Tour in just four weeks when he unexpectedly triumphed at the Celtic Manor Wales Open.

Following the recent out-of-the-blue victories of Irish amateur Shane Lowry and world number 449 Christian Cevaer, the 26-year-old Dane, ranked 377th in the world, beat Swede Niclas Fasth by one - his first top-10 finish on the circuit in 45 attempts going back six years.

"It feels amazing," he said. "I couldn't feel my hands the last three holes. I knew I was doing well, but I didn't know how well until I asked my caddie on the 18th tee.

"He told me I needed a par - and it's nice to have a par five and have a chance to lay up. But I couldn't put winning out of my head and it was quite emotional."

The £300,000 first prize was almost 30 times Huldahl's previous biggest cheque, but he won in real style on the course which in October next year will stage America's defence of the Ryder Cup.

Joint leader with England's Nick Dougherty and Spaniard Ignacio Garrido with a round to play, the 2008 Challenge Tour graduate did not drop a stroke in shooting a four under par 67.

Fasth joined him out in front by pitching in for eagle on the long 11th, but Huldahl instantly birdied his next two holes.

Fasth came back at him with birdies on the 13th and 15th, but the former world top 20 player then bogeyed the next two holes and despite piling on the pressure again with a closing 20-foot putt, Huldahl parred the last seven holes to triumph.

He finished at nine under par for the tournament, with Fasth eight under after a 66 and Garrido third a further shot back.

Dougherty, though, tumbled all the way down to 37th with a nightmare 79.

Halfway leader Richie Ramsay, meanwhile, finished tied 10th, but it was a weekend the Scot will not forget in a hurry.

After two-hour talks with officials late on Saturday night he escaped a two-stroke penalty over an incident on the eighth when he pressed down ground behind his ball in testing for casual water, but on Sunday had his par five on the last turned into a six because of the way he took relief on the fairway there.

"I didn't sleep because I was concerned about what people might think and my head was in a bit of a spin," said the Tour rookie, who during his US Amateur victory three years ago lost two holes over rules matters.

"A lot of things go through your head, but all I can do is tell the truth.

"That's what golf is about - honesty and etiquette. Being up most of the night it wasn't the easiest thing to come out and play. I just need to sit down now, have a rest and clear my head."

Tour chief referee John Paramor, shaking his head in disbelief when the second incident happened, said of the first: "He now knows that's not the way to go about it.

"If he's absolutely positive he did not improve his area of swing then I can't impose a penalty on him based on what I've seen. I must have looked at it about 20 times on television, but we had only one camera angle."

Focal points at the start of the week were Ryder Cup captains Colin Montgomerie and Corey Pavin, but they finished 38th and 43rd respectively on three and four over.
