No. 4, 331 yards, par 4: This was the only par 4 that played under par during the U.S. Open, and it begins a beautiful, seven-hole stretch along the ocean. The tee shot must clear a cross bunker. A driver will put the ball just short of the green, although it's a high risk for a shot demanding accuracy with a bunker to the left and ocean to the right. Most players will hit a fairway metal, leaving a wedge to a green that is surrounded by bunkers and pitches steeply to the front. Anything above the hole leads to a difficult putt. John Wood, Hunter Mahan's caddie: "It's one of the best birdie chances you'll have during the U.S. Open."
