Day 12: The Only Yardage You Really Need

It's amazing how an obstacle between you and your target—a water hazard, deep bunker, even really thick rough—can get into your head and mess up what's otherwise a pretty basic shot. Do what tour players do on an approach shot like this. Get three yardages: a safe number that puts you clear of the trouble, a distance to your ultimate target and one to the back of the green. The distance you want to use for club selection should be a little less than the back-of-the-green number. Knowing you have plenty of leeway if you don't catch it exactly right, you should feel free to swing under control.
