10. Baltimore Country Club (Five Farms East) (above)
Timionium, Md., 1926
Leo Diegel snapped Walter Hagen's PGA Championship winning streak at four when he triumphed here in 1928. More recently, Loren Roberts captured the Senior Players Championship in 2007 by skillfully handling the severely breaking greens and memorable par-5s such as the "Barn Hole" 6th and the endless 14th, with its "Hell's Half Acre" bunker complex.

9. Ridgewood Country Club
Paramus, N.J., 1929
• Ranked No. 87 in the U.S. by GOLF Magazine
The classic argument at Ridgewood centers on which of the three nines is best — the East, West, or Center. Holes from each have been used at tournaments such as the 1935 Ryder Cup, the 1990 U.S. Senior Open (when Lee Trevino defeated Jack Nicklaus) and the 2001 Senior PGA when Tom Watson got it done. Best of the bunch might be the 291-yard 6th on the Center, which offers a half-dozen routes to the elevated green.
