Rule 21 of 25 · Chapter IV — Numbers, Lies, and Greens
Change trajectory with ball position and finish height, not by adding or subtracting wrist action.
Why this rule exists
Flighting a ball by manipulating your wrists through impact changes the low point and the face angle at the same time, so you get a different height and a different direction and a different strike quality. Ball position and finish height move the flight while leaving the delivery you already trust intact. One is a setup change you can repeat; the other is a hand action you have to time.
In practice
To hit it lower, move the ball back a ball-width or two, let your hands sit slightly more forward, and finish with the club lower and shorter — chest-high rather than over your shoulder. To hit it higher, put the ball a touch further forward and finish tall and full. Make the same swing at the same speed either way and let the setup and the finish do the work.
When it doesn't apply
A genuine punch-out under branches or a deliberate high, soft lob from a tight lie are specialty shots with their own techniques, and both involve hand and face changes you should practise separately. Advanced players who have grooved a flighted wedge with a shorter, quieter release can use it — but not as a fix for a strike problem.
