Pebble Beach saves its best for last. After a downhill plunge on the 16th, players emerge from the trees and back out onto the cliffs overlooking the Pacific. There they are faced with one of the most difficult par 3s in golf. The tee shot is made straight towards the ocean and always into the teeth of an unpredictable wind. To get anywhere near the pin, the ball must carry 200 yards of fairway and avoid the catcher's mitt of sands that grips the green. Tournaments are often won or lost here, and if not on this very hole, then on the next. Should dreams of victory survive the 17th, there is still the 548-yard clifftop 18th waiting to spoil them.
