Ah my friend, you have forgotten our old friend Shivas Irons, who reminded us: “Aye one field afore ye e'er swung. Our boy TW has lost his connection to the "field". FEAR, (False Expectations Appearing Real) has reared it's ugly head and set up camp in his golfing soul (AKA the putting stroke) He is headed into the abyss, the eternal resting place for the greats of yesteryear... Foley, Haney, Harmon- all pawns, mere bit players on the stage where fear and doubt are featured. As that great American Philospher, Sam Snead, once so eloquently quipped: "The yips: once you've had em, you got em"!
Take the same putting stroke and wedge swing he has right now, not one change, execute them with more self belief (will) and my money is on better results. Ever play a great practice round and suck in the tournament?
