Your distance is hiding in your wrists — but not in the way most golfers try to spend it.
At the top of the backswing, your lead wrist and the club form an angle, somewhere near 90 degrees. That angle is stored speed. Keep it deep into the downswing and the clubhead whips through at the last moment, arriving at the ball at maximum velocity. Spend it early and the whip happens up near your shoulder, where there's no ball to hit.
Casting is spending it early. The name comes from fishing: the first move down throws the clubhead outward, wrists unhinging immediately, exactly like casting a line. By the time the club reaches the ball, the angle is gone, the speed has peaked and faded, and the clubface arrives with extra loft — those high, soft irons that land two clubs short of your friends'.
Why you cast
Almost never because your wrists misbehave on their own. Casting is usually a transition problem in disguise. When the downswing starts with a snatch from the top — arms and shoulders firing first — the throwing motion is baked in from the first inch. And under it all often sits the oldest instinct in golf: trying to help the ball into the air, when the loft was going to do that anyway.
There's a number that tells on this pattern. A swing that snatches from the top compresses its backswing-to-downswing ratio well below the 3-to-1 tour benchmark — and that ratio is a number CoachVision pulls from one slo-mo clip. A rushed ratio and a cast tend to travel together.
The drill — L-to-L Swings
This drill teaches your wrists where the angle gets spent — not by holding anything, but by rehearsing the shape.
Take a wedge. Swing back until your lead arm points at 9 o'clock — parallel to the ground — with your wrists fully hinged, so arm and club form an "L." Then swing down and through to the mirror image: trail arm at 3 o'clock, wrists rehinged into an "L" on the other side.
The magic lives between the two L's. To arrive at that finish position, the wrists have to unhinge at the ball — not before — and rehinge after. You're not gripping tighter or holding lag by force; the shape itself schedules the release for the right moment.
Do 15 reps with a wedge, smooth and unhurried, ball optional at first. Listen to the strike when you do add a ball: a cast sounds like a scoop and feels like nothing; a properly timed release makes that compressed click and comes off lower and hotter than you expect from a half swing.
The speed you've been muscling after has been in your hands all along — just spent at the top, where nobody can use it. Move the spending to the ball, and the same swing finds a gear you didn't know it had.
