Sweden’s Joakim Backstrom won the Aa St Omer in northern France with a par at the first play-off hole to defeat England's Paul Dwyer.
Dwyer had a two-foot putt for par on the first green but dragged it wide and the 27-year-old Backstrom holed from inside that range to claim a one-year exemption on the main tour for winning this co-sanctioned event between the European and Challenge Tours.
The tournament swung on the 15th when leader James Heath, with a two-shot lead over his rivals, missed the green on the short-side and left himself with an incredibly difficult 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.
Ireland's Stephen Browne finished tied for 17th place on par after he shot a 72 today which included four birdies and five bogies.
David Higgins finished tied for 30th place on two over after his 71 today.
