Finland's Mikko Ilonen claimed his second European Tour victory of the 2007 year in dramatic fashion in the Scandinavian Masters in Stockholm.
Ilonen, who won the Enjoy Jakarta Astro Indonesia Open in February, birdied the par three 18th hole at Arlandastad Golf after a fantastic four iron tee shot to join Martin Kaymer on six under par as the young German looked on from the tee.
Kaymer then missed the green with his approach and was unable to save par, his weak chip failing to climb the steep slope up to the green and rolling halfway back down.
The resulting double bogey five dropped him back into a share of second place on four under par 276 with French pair Jean-Baptiste Gonnet and Christian Cevaer, local favourite Peter Hedblom and England's Nick Dougherty.
Ilonen, who collected the first prize of €266,660 (£180,000) to move to 27th on The European Tour Order of Merit, looked to have blown his chances when he double bogeyed the par three 16th after finding water with his tee shot.
But the 2000 Amateur champion shrugged off missing a short birdie putt on the next to hole from five feet on the 18th for a closing 68 and a six under par total of 274 and it was Kaymer who eventually cracked under the pressure.
"It's an unbelievable feeling," said Ilonen. "If I had to pick one tournament to win, alongside the Majors, it would be this one.
"You all saw the support we get from the crowds, it's something we don't get every week and I hope some other tournaments can learn from this. It's unbelievable for the players to be out there."
Three behind Kaymer and South African James Kingston going into the final round, Ilonen led by one after a birdie on the 15th but promptly found water on the next and, after donning his waterproof trousers, could only splash the ball out a few feet.
It rolled back almost into the water again and from there the 27 year old chipped to five feet and missed the bogey putt.
Asked if he thought his chance had gone, Ilonen said: "No, I knew Martin still had to play the 16th and you can make a bogey there in a heartbeat. I knew it was going to be a tough finish for him if could make one or two birdies and that's what happened.
"It's the first time I've hit the 18th green all week, including a couple of attempts in the practice rounds. My playing partner Paul Broadhurst hit his three-iron a little fat and it still ran through the green so I knew it was a perfect four iron for me."
Kaymer won two tournaments on the Challenge Tour last year but has now twice failed to convert winning positions on The European Tour.
The 22 year old shared the lead going into the final round of The Celtic Manor Wales Open before fading to 14th with a one over par 70 in the final round, and finished with a 73, three over, at Arlandastad .
"I'm very disappointed, especially with my play over the first five holes when I made two bogeys," he said. "That really wasn't the start that I wanted and after that it was always a bit of a battle all day.
"I tried to stick to my game plan but it didn't work out, but now I'm looking forward to my next tournament in the Johnnie Walker Championship at Gleneagles and I'll try to go one better there. But this is another tournament where I think I have learnt a lot about myself."
Dougherty's second place was his seventh top ten of the season but the 25 year old Englihsman never threatened to claim his second European Tour victory.
Starting the day three off the lead, the protege of six-time Major winner Nick Faldo bogeyed the second and despite a birdie on the fourth, effectively saw his chances ended with another dropped shot on the 13th.
Playing alongside Ilonen, Broadhurst had hoped to mark the premature end to his season in style with a victory, but could only manage a closing 71 for a share of seventh place.
The 42 year old's wife Lorraine is undergoing surgery next week and Broadhurst will take a long break to look after her and their four children.
A superb third-round 64 had dragged the former Ryder Cup player into contention on four under par but birdies at the sixth and 11th were cancelled out by bogeys on the ninth, 13th and 18th.
