Cupped Wrist
Also known as: extended wrist, open face at the top
A cupped wrist is a lead wrist bent backward (away from the palm) at the top of the backswing. It opens the clubface and often contributes to slices or weak fades.
In golf, a cupped lead wrist is a position where the back of the lead wrist bends backward, away from the forearm. This creates a concave "cup" shape on the back of the wrist. At the top of the backswing, a cupped lead wrist opens the clubface relative to the swing plane. That makes a slice or a fade more likely. The hands must also work harder through impact to square the face. It is one of the most common characteristics of recreational golfers who reliably slice or fade the ball.
The mechanism is direct: the lead wrist angle controls the clubface angle throughout the swing. When the lead wrist cups, the toe of the club falls away from the palm direction and the face opens. An open face at the top of the backswing leads to one of two outcomes. Either the golfer must rotate the hands aggressively through impact to close the face, which makes the swing depend on timing and less consistent. Or the face arrives at impact still open, producing the left-to-right ball flight of a slice.
Cupping occurs for several reasons. One is a weak grip that does not support the wrist through the backswing. Another is a takeaway that swings the club too much around the body. That forces the wrist to cup to keep the face pointed at the target. A third is a deliberate attempt to "keep the face square" by holding it pointed at the target during the backswing. The fix usually begins with a grip adjustment. Moving to a neutral or slightly strong grip removes much of the structural pressure that creates cupping. Then the golfer lets the wrists respond naturally to the arm swing instead of consciously holding them.
A cupped wrist is most easily corrected by strengthening your grip slightly: rotate both hands clockwise on the grip (for a right-hander) until you can see 2–3 knuckles on the lead hand at address — this structural change reduces the tendency to cup without requiring any conscious wrist adjustment during the swing.
Practice the top-of-backswing position in front of a mirror: at the top, the back of your lead wrist and the back of your lead forearm should be in a continuous flat plane — any cupping or bowing visible in the mirror tells you immediately how much correction you need, and you can train the position in slow reps without having to hit balls.
Example
A golfer at the top of the backswing where the lead wrist bends backward (thumb points at the sky) has a cupped wrist and an open face.
How it shows up on video
From a face-on camera angle at the top of the backswing, a cupped lead wrist is visible as the back of the lead hand arching upward and away from the forearm, with the clubface appearing to point at the sky (open). The palm of the lead hand will appear to face the sky. From a down-the-line camera angle at the top of the backswing, the cupped wrist shows the clubface tilted skyward rather than parallel to the lead forearm — if the clubface were to show in the camera, it would point more toward the sky than the down-the-line view angle.
Common mistakes
- Trying to "keep the clubface square" throughout the backswing. This well-intentioned goal often produces cupping because the golfer manually holds the face pointing at the target as the body rotates. This forces the lead wrist to cup to accommodate the rotation.
- Using a weak grip and expecting good face control. A weak grip (hands rotated to the left on the club for a right-hander) provides no structural support for the lead wrist and almost inevitably produces cupping. Grip adjustment is the first step.
- Correcting cupping by adding forearm rotation rather than wrist position — rotating the forearms in the backswing closes the face but does so by a different mechanism than correcting the wrist cup. The two movements have different feels and different implications for the downswing.
- Fixing the cupped wrist at the top without checking impact — correcting the wrist position at the top is only useful if the new top position translates into better face control at impact. Some golfers have cupped wrists at the top but square impact through strong compensations; for them, changing the top position disrupts working impact habits.
In SwingVantage Motion Lab
Golf gets no wrist angle in Motion Lab, so a cupped lead wrist is not detected. The clubface is not tracked either. Imported launch-monitor face-to-path numbers, labeled with the device, show the open face a cup can cause. For your own check, pause a face-on clip at the top: a cupped wrist arches the back of the hand away from the forearm.
Related terms
- Bowed WristA bowed wrist at the top of the backswing means the lead wrist flexes toward the palm (like a bow), closing the clubface and storing power for a powerful, face-controlled delivery.
- Lead WristThe lead wrist is the wrist of the top hand (left for right-handers). Its position throughout the swing — especially at the top of the backswing and at impact — directly controls clubface angle and low point.
- SliceA slice bleeds away to the right for a right-handed golfer, costing both distance and fairway. It is the most common miss in the game, and it comes from a face pointing right of the head's direction of travel.
- Face AngleFace angle is where the clubface points at impact, relative to the target line, in degrees. It determines roughly 75–85% of the ball's starting direction.
