I eavesdropped on Saturday setup and came away just astounded at the difficulty of Shinnecock Hills under tournament conditions. The difference in speed and firmness from a week ago is pretty profound, with more dryness and difficult days ahead.
So if you're wondering how you'd handle this monster of a course, you'll enjoy Eamon Lynch's premise of asking players what a 4.3 Index like USGA CEO Mike Davis would shoot on the course he's preparing with Jeff Hall.
Davis's answer might be the best:
“90 plus,” he shot back with the good humor of a man who knows this course is designed to test the best, not the rest. “Assuming I did not run out of balls.”
