David Duval kept his cool on a dramatic final day to claim his first major title in the 130th Open championship at Royal Lytham.

But Ian Woosnam was left to ponder what might have been after an elementary blunder ruined his chances of victory.

Duval carded a final round 67 to finish on 10 under par for a three stroke victory over Niclas Fasth, a result that almost certainly earns the Swede a place in the European Ryder Cup team.

Woosnam had to settle for joint third on six under, alongside Darren Clarke - who was Duval's closest challenger until a double bogey six on the 17th - Bernhard Langer, Miguel Angel Jimenez, Ernie Els and American Billy Mayfair.

The Welshman had made a spectacular start to his final round when he almost fired a hole-in-one on the first, his tee shot stopping inches short of the hole to set up a simple birdie that earned him a share of the lead at the time alongside Fasth.

That lasted only a matter of seconds however as the former Masters champion discovered to his horror on the second tee that he had 15 clubs in his bag, one more than the number allowed.

It meant an automatic two shot penalty - and would have cost him two more shots if he had hit his tee shot - and turned a birdie two into a bogey five, the 43-year-old snatching the offending club from his bag and throwing it across the tee in disgust.

Somehow he managed to par the second hole but it was no surprise when he bogeyed the third and fourth before an eagle on the sixth kept his slim hopes alive.

Further birdies on the 11th, 13th and 16th followed but bogeys on the 15th and 17th kept him out of a share for second place and forever wondering what might have been.

Duval meanwhile went calmly about his business, carding five birdies and just one bogey, and could enjoy the ovation on the 18th hole with a three shot he kept in tact with a routine par.
