Yes. Huge mental choke.
Far-AwayFairways. com - "The 18th hole went into legend however when the Open returned to Carnoustie for the first time again in 1999. Frenchman Jean Van de Velde stood on the 72nd tee with a three shot lead of the Open Championship. As he withdrew a driver from his bag people looked on with incredulity and some audible murmurs of disapproval were clearly heard. He duly hit a wayward shot that went off towards the seventeenth fairway, but it was playable, surely he’d learnt his lesson? Nope!!!. The next club he took was a 2 iron!!! He hit the grandstand and with a wicked bounce found a horrible lie in deep rough. Not to be deterred though he duly turned concern into disaster and chipped into the ‘Barry Burn’ in his attempt to reach the green rather than playing laterally. Assessing his worsening predicament Jean decided the only answer was to go fishing, and began the torturously slow process of theatrically removing his socks and shoes!!! In truth, it was probably this animated act that cost him the Open.
The ball had come to rest on a water shrub. Enough of it was clear of the water to permit a shot. It was this that persuaded him to investigate. Van de Velde later said that the weight of the ball had pushed down on the shrub causing it to dip below the water. No it hadn’t! What he didn’t know was that the burn is tidal. As he continued the ceremonial socks and shoes routine time was ebbing away. The tide was coming in. Had he got straight into the burn and played it, he would in all likelihood have escaped, and been holding the claret jug with wet feet
After much deliberation and surveillance of his stricken ball, he started to take some practise swings. Ultimately common sense prevailed. Contrary to popular folklore Van de Velde didn’t actually try extracting his lie from Davy Jones’s locker and elected to take the penalty drop. His pitch however fared little better and scurried across the putting surface before dribbling into a green-side bunker. He completed a triple-bogey 7 to see him tie and ultimately lose in a play-off to Paul Lawrie. Today his exploits have been cemented into the walls of the Barry Burn by way of a tribute."
