Adam Scott was on the verge of winning his first major championship. He had a four-stroke lead going into Sunday's final round of the British Open at Royal Lytham & St. Annes and held that same advantage after a birdie on the 14th hole.
It was the last time he was under par for the rest of the day -- he never even made par on those last four holes. Instead, the Australian put together a stunning string of bogeys that gave Ernie Els the victory and left Scott's major championship drought intact.
Such a collapse is always tough to watch, and we've had to endure some pretty colossal ones over the years. Perhaps the one that jumps to mind first, at least when thinking about the British Open, is Jean Van de Velde's triple bogey on the 18th in 1999, forcing a playoff that was won by Paul Lawrie.
Rory McIlroy's utter implosion at last year's Masters is still fresh in everyone's mind. Who can forget the poor guy knocking the ball around places at Augusta many people had never even seen before to finish after looking like he was going to run away with the green jacket for most of the tournament.
Even some of the all-time greats had days similar to Scott's, such as Phil Mickelson at the 2006 U.S. Open, Arnold Palmer at the 1966 U.S. Open and Greg Norman at the 1996 Masters.
