Put yourself in his shoes. It is the final round of the year’s final major – the PGA Championship. You are not in contention to win but you want to finish well. You are on the 11th hole and a little frustrated at not making par. You go to tap in your bogey putt. It is only 3 inches. As you move toward the ball, your not thinking. You just move to tap it and go right over the top of the ball. You move again, reflexively, and tap it in. On to the 12th hole, where you grind out the first of five pars before birding the 18th for a final round 69. You tie for 33rd and earn $53,000. Not bad but you had hoped for more. You were hitting the ball so well all week. The thought even came to your mind that maybe this was your week to win. Just couldn’t get the putts to fall.
Later that day, as you reflect on the round, something starts gnawing at you. Did you actually make a stroke and whiff that putt on 11? You try to remember but it happened so fast. Because you were acting on reflex, you can’t really remember. You dismiss it, “No, if I would have whiffed it outright I would remember that.
