Bourdy played his last 20 holes at Pula Golf Course without a bogey, carding three birdies in the final round to win by two shots over Sam Little at 12-under 268.
Perhaps anticipating the inevitable champagne shower from his fellow Frenchmen, Bourdy missed a 3-foot birdie putt at the 18th green with a chance to close out his maiden victory in style.
He led by two shots already, so it didn't matter. With a noticeable smirk on his face, Bourdy calmly tapped in for par and awaited the celebration.
It came in the form of several charging Frenchman and a wall of bubbly, nobody taking more pleasure in spraying the new champion than former Ryder Cupper and three-time European Tour winner Thomas Levet.
Bourdy became just the ninth Frenchman to win on the European Tour. The champagne celebration has become customary for many of them over the last several years.
'To get my first win on tour feels absolutely fantastic,' said Bourdy, who won on South Africa's Sunshine Tour last year. 'I had a great day out there and this is just unbelievable.'
Little carded a 67 in the final round and ended alone in second place at 10-under 270, his best finish on the European Tour. It clinched his playing status for 2008.
Robert-Jan Derksen shared the lead with Bourdy when the third round was completed Sunday morning, but he managed only an even-par 70 in the final round to end three shots back at 9-under 271.
Alastair Forsyth shot a 66 and finished in fourth place at 7-under 271, while Johan Edfors (67) and Peter Lawrie (72) tied for fifth at 6-under 274.
Sergio Garcia, the 2004 champion, had a 73 in the final round and was nine shots off the winning score at 3-under 277.
Bourdy's most important score of the day was not a birdie -- it was his scrambling par at the 442-yard 16th. He pulled his drive into the rough, then had his club get stuck in the grass on his second shot.
The ball looked for sure like it would land in the water. But, with Little looking on from the next fairway, it landed just a foot above the edge of the hazard and Bourdy managed a nice up-and-down for par.
'I did think it was in the water at the 16th, so I was very relieved when I saw it bounce in the rough in front of the green,' said Bourdy, the 18th first-time winner this season.
'It was a bit lucky, but sometimes these little things go your way and perhaps that signifies that it is your day.'
