The old horse racing expression often applies in golf as well.
"There are horses for courses and courses for horses."
Sometimes a horse can feel great at one racetrack and run his best race there, but he may struggle at a different track even if nothing in his pre-race routine has changed.
It's certainly true in golf, and Tiger Woods is one of the greatest examples. He won in stellar fashion last week at the Bridgestone Invitational. But moving from Firestone Country Club in Ohio to Oak Hill Country Club in New York showed that Tiger was simply not able to translate his skill from one classic course to the next.
Tiger was never able to contend for the PGA Championship, and he did not break par in any of his four rounds. That means he has failed to accomplish that feat in any of the eight PGA Championship rounds he has played at Oak Hill.
