David Duval was the third golfer to ever shoot a 59 but the first to do it in the final round of a tournament.
Duval pulled it off at the 1999 Bob Hope Classic. Despite a tremendous round, Duval still needed a an eagle three on the par-5 18th hole.
His second shot was a 5-iron that drew him to within six feet of the hole. That set up a dramatic putt for his 59.
