Tournament: 2005 Masters Tournament, Augusta National GC.

Hole: 16.

Golf can be cruel. Billy Casper (pictured, red sweater) won the Masters in 1970, which allowed him a lifetime entry into the tournament. Years later, in 2005, Casper teed it up on the fabled par-3 16th hole, and what followed was a nightmare that would go down in the history books as the highest single-hole score ever at the Masters. Five shots in the water were only the start of his infamy.

Score: 14.
