→Erasing your mistakes—not hitting perfect shots—is what good golf is all about. I've certainly had tournaments where I felt I was swinging great (like the 2011 U.S. Open, when I hit 86 percent of the greens in regulation). But as special as those weeks are, I have to say that nothing makes me more confident than when I'm getting up and down from almost any missed approach shot. Perfect example: This spring when I won the BMW PGA Championship at Wentworth, I got up and down four times and chipped in another to shoot 32 on the back nine on Sunday. If you're confident with your short shots, you can manage your game when other areas are weak. And when your greenside play is strong, every part of your game gets stronger. Study all your options for shots around the green. The shot you hit should be the shot you know you can hit, not the one you think you might be able to hit.
