You often encounter shots from non-level stances on uneven contours around the greens which wreak havoc on your wedge results. Suddenly your wedge swing is bottoming out in a different spot relative to your stance and you may be at a loss as to where you should position the ball. Enter green-then-white contact and a heavy dose of extra strokes from short range.
The danger is hitting your approach past the hole. Make this mistake and you’ll face one of the most challenging putts you can imagine. From the back-left to a front-right pin it’s a roller-coaster ride. Expect a lot of three-putts.
To launch a good wedge shot it’s important to strike the little white ball (with the dimples) before you hit the big green one (the earth). And since every swing has a bottom to its arc you need to position the white orb just behind it so that your contact goes “white-then-green”—not vice versa.
