This is not where you want to be especially during a major. To prove it I threw six balls into the grass in this area during my fall visit; the photo at right shows the only time I was able to lash the ball onto the green (and it eventually rolled off the back).
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.
For this “Backspin vs. Lie” experiment you’ll need your lob wedge a tee and three balls. Select a 20- to 30-yard shot around a green that forces you to carry a bunker but that provides plenty of room between the apron and the pin.
