Tom Watson unveiled a plaque to commemorate his famous Duel in the Sun with Jack Nicklaus 35 years ago upon his return Wednesday to Turnberry on the eve of the Senior British Open.

In 1977, Watson hit a 7-iron approach within two feet of the 18th hole in beating Nicklaus in a head-to-head battle to seal the second of his five British Open titles. The weather was remarkably similar 35 years later for the plaque's presentation on the right side of the final fairway.

Watson says "I remember hitting the shot which meant so much to me and so many other people."

Watson will tee off Thursday alongside another former British Open champion at Turnberry, Greg Norman, plus Roger Chapman of England, who has two senior majors this year.
