T-7. David Duval
Tournament: 2019 British Open, Royal Portrush.
Hole: 7.
Much like Billy Casper, golf welcomed Duval’s lifetime entry into the British Open with nightmarish arms. The 2001 Open champ got to the par-5 seventh in pretty good shape. But the hole quickly turned into an assortment of errant tee shots, playing the wrong ball, and yes, a miscalculated score: It was originally marked a 13, but Duval found later it was even worse.
Score: 14.
