Congressional Country Club, where Tiger Woods won the 2012 AT&T National, is one of the most difficult courses players will face all year.
Not all PGA Tour golf courses are created equally. Aside from the contrast in terrain, types of grass and natural surroundings, the scores players shoot at particular courses highlights the divide between those where we expect to see a birdie-fest and those where par can be a man's best friend.
For example, Russell Henley, a Tour rookie, won in his very first start at the Sony Open in Hawaii with a remarkable 72-hole score of 24 under at Waialae Country Club. While beautiful, no doubt, Waialae is flat and lends itself to low scores.
