Lancashire's Paul Dwyer missed two crucial putts - one on the final green and another at the first play-off hole - to hand victory at the Aa St Omer Open in northern France to Sweden's Joakim Backstrom.

The Clitheroe golfer watched a 12-foot birdie attempt on the 18th slide narrowly past which would have given him the outright lead at five under.

He had to settle for a round of 68 and when Backstrom shot a 70 to also finish four under the pair headed to the first at this co-sanctioned event between the European and Challenge Tours.

Dwyer dragged a two-foot par putt wide and the 27-year-old Swede, ranked 810 in the world, claimed the £44,500 first prize and a one-year main tour exemption from inside that range.

"This means the world to me. I have guaranteed starts until the end of 2006 and I can start to plan and play in the really big events," said the Swede.

St Helens-born Dwyer went to the turn in 34 with birdies at the fourth and eighth and two more followed at the 12th and 17th with his only dropped shot of the day at the par-five 14th before he almost snatched it at the last.

He then had to sit for more than 90 minutes but only Backstrom matched his total as the strong English challenge, led by Surrey's James Heath, faded away.

The 22-year-old Nick Faldo protégé finished in a tie for third despite leading by two at six under with five holes to play.

Dwyer headed to the range to begin his preparations for the play-off but discovered there were no balls and so had to resort to a spot of chipping and putting but he refused to blame that on his near-miss.

"It is tough way to finish. I was in the clubhouse for an hour and a half and was on a massive high when I came in and felt a little jaded on the [first] tee," said Dwyer, who finished fifth in this event in 2002.

"I missed a little putt but that's the way it goes. It is the first time it (a play-off) has ever happened for me so I'll learn from that.

"Obviously it is nerve-wracking, you see people coming in, and there is so much to play for - your tour card for next year."

The tournament swung on the 15th when Heath, with a two-shot lead over his rivals, missed the green on the short side and left himself with an impossible flop shot over a bunker with only eight feet of putting surface to work with.

He finished in the fringe a good 15 feet away, raced his par putt six feet past and missed the return.

Then on the last he again missed the green to the right, duffed his chip and failed to hole a 10-foot par putt to book his place in the play-off.

Heath had gone out in 35 after birdies at the first and ninth and a bogey at the par-four fifth.

Another birdie at the 14th gave him that two-shot cushion before disaster struck at the next and his position of strength dissipated.

"I'm extremely disappointed but at the same time I hit bad shots at the wrong time it wasn't anything else," said the 22-year-old.

"On 15 my grip slipped on the way down and I hit a bad shot. I was maybe a bit aggressive with my par putt but I was happy with the way I conducted myself after that.

"I hit some good shots on the way in but unfortunately a bad chip and a bad putt and I lose the tournament - but it happens unfortunately."

English trio Ross Fisher, James Hepworth and Ben Mason all finished tied for sixth.
