One thing that I observed at the Masters was differences in pre-shot routines and temperament. Basically the less time the players took over the ball before they hit it, the better the shot was. I watched Jordan Speith take an eternity over his tee shot with lots of pumps and waggles then chunk it 30 yards short of the green, while Tiger just got up and hit it. The clearer the decision making and less hesitation, the better the outcome. I did watch Henrik Stenson lose his cool on hole #13. He hit his second shot into the azaleas, which needed an unplayable ball drop. He took his drop, then chipped it out into the water on the other side of the green. After learning that his ball went into the water he attacked some azalea bushes then tried to put them back after the attack. I bet he got a huge fine for that incident!
