An interesting note: John called me Sunday morning before the forth round. He said "I'm hitting it on the button but I can't make a putt. I'm leaving everything short, any suggestions". I said "use your Horizontal Hinge just like you do in your swing for maximum compression". He when out and shot 66. He called back Monday morning and said "it worked".
In a relative world, this fact is relevant:
John Riegger's final round 66 tied for third low of the day.
