Jean Van de Velde, 1999 British Open
Jean Van de Velde needed only a double bogey on 18 to win the 1999 British Open at Carnoustie. His third shot on 18 landed in the Barry Burn, and for a moment he considered hitting out of the water. He took a drop and hit his fifth into a bunker. He got up and down for a triple bogey and a spot in a playoff, which he eventually lost to Paul Lawrie.
