No. 4 combines the classical routing of Donald Ross with the contemporary vision of Tom Fazio, who re-imagined the course. Fazio, who considered No. 4 his tribute to Pinehurst, 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.
Most agree that Fazio elevated a good course to a great one with his work on No. 4. Indeed, it was selected as the co-site of the 2008 U.S. Amateur.
