No. 4 combines the classical routing of Donald Ross with the contemporary vision of Tom Fazio, who re-imagined the course in 2000. Fazio tipped his hat to Ross with crowned greens on many holes, and the addition of more than 140 pot bunkers. These, combined with several sprawling waste bunkers and more traditional sand traps, give the track a dizzying 188 sand hazards.
Though adjacent to No. 2, No. 4 has a distinctively different look, in large part thanks to the lake that acts as its centerpiece. The lake comes into play on several holes, including the par-5 13th, which demands a drive to a small landing area bounded by the lake on the left and bunkers on the right.
The co-site of the 2008 U.S. Amateur, the course will host the 2017 U.S. Amateur Four-Ball Championship.
