What Is Cupping the Wrist in a Golf Swing?

By Spencer Lanoue

A cupped wrist at the top of your golf swing quietly sabotages your power, accuracy, and consistency by leaving your clubface wide open. This common position issue is one of the leading causes of the dreaded slice and weak, high-flying shots. In this guide, we'll break down exactly what a cupped wrist is, show you how to see it in your own swing, and give you practical drills to fix it for good.

What Exactly is a "Cupped" Wrist in Golf?

To understand what it means to "cup" your wrist, let's first get a clear picture of the three main positions your lead wrist (the left wrist for a right-handed golfer) can take at the top of the swing.

  • Cupped (Extension): This is when the back of your lead hand creates a U-shaped angle, with your knuckles pulling back towards the top of your forearm. If you were holding a tray, you'd be spilling it backwards. This action moves the clubface into an open position.
  • Flat (Neutral): A flat wrist means the back of your hand and forearm form a relatively straight line. It's a strong, neutral position that most elite golfers strive for. This position typically keeps the clubface "square" relative to your swing path at the top.
  • Bowed (Flexion): This is the opposite of cupped. Your knuckles move down towards the ground, rounding your wrist forward. Think of the motion you make when revving a motorcycle throttle. Famous examples include Dustin Johnson and Jon Rahm. This position closes the clubface.

While a tiny bit of cupping, or extension, is normal in many golf swings, the term "cupping the wrist" generally refers to an excessive angle. This over-extension creates a disconnect between your arms and the club, making it incredibly difficult to deliver a powerful and square clubface to the ball.

Why a Cupped Wrist Is a Secret Swing Killer

It might not look like a huge deal, but that slight angle in your wrist at the top of your swing sets off a chain reaction that ruins impact. The position of your lead wrist is the undisputed steering wheel for your clubface. When you cup it, you're pointing that steering wheel off the road. Here’s why it’s so damaging.

It Opens the Clubface and Causes a Slice

This is the big one. Cupping your wrist directly opens the clubface. An open clubface at the top of your swing means you have to make a heroic, perfectly-timed compensatory move on the way down just to get it back to square. Most recreational golfers simply don't have the time or a fast enough rate of clubface rotation to save the shot. The inevitable result? The club slaps across the ball with an open face, putting left-to-right spin on it and sending it slicing into the trees.

It Robs You of Power and Compression

To hit a golf ball with that satisfying "thump" of pure compression, you need to deliver the clubface squarely with a slightly descending blow. A cupped wrist makes this almost impossible. As you come into impact with an open face, you end up adding loft and wiping across the ball instead of compressing it. Shots don't have that penetrating flight, instead, they fly high, float weakly, and land short of your target. You’re swinging hard but the energy isn't transferring into the ball because the clubface isn't stable.

It Breeds Inconsistency

A golf swing that relies on a last-millisecond "flip" of the hands to square an open clubface is a recipe for wild inconsistency. On the rare occasion you time it perfectly, you might hit a great shot. More often, you’ll be slightly too early or slightly too late.

  • Slightly late? That’s your classic slice or high, weak push to the right.
  • Slightly early? You over-correct and snap the clubface shut, causing a violent pull hook to the left.

If you suffer from the dreaded two-way miss, an overly cupped wrist is one of the first places you should look.

How to Know If You're Cupping Your Wrist

Alright, so you suspect you might be a victim of the cupped wrist. How do you find out for sure? Luckily, it's pretty easy to diagnose. Forget guesswork, you need to see it for yourself. Here are two definitive ways to check.

1. The Video Test (Most Accurate)

Your smartphone is your best friend here. You can't rely on feel alone because your bad habit will feel "normal" to you.

  1. Prop your phone up on a golf bag or tripod to film your swing. You need a "down-the-line" view, which means the camera is positioned directly behind you, looking straight down your target line.
  2. Take a few normal swings like you're on the course.
  3. Review the footage in slow motion and pause your swing at the exact top of your backswing.
  4. Look at your lead wrist: Do you see a distinct 'V' or 'U' angle in the back of your wrist? Does it look like the back of your hand is angled up towards the sky? If yes, that's cupping. A flat wrist will look like a straight line from your forearm through your knuckles.
  5. Look at the clubface: With a cupped wrist, the toe of the club will be pointing more towards the ground than it should. A square clubface (usually associated with a flat wrist) will typically be at about a 45-degree angle or parallel to your lead forearm. An open face pointed toward the ground is a dead giveaway.

2. The Tabletop Drill (Feel Check)

If you don't have a camera handy, this simple drill can help you feel the difference between a cupped and a flat wrist.

  1. Take your normal setup without a club.
  2. Make a practice backswing rotation with just your arms.
  3. At the top of your swing, hold your lead hand (left hand for righties) out as if you were a waiter balancing a tray of drinks. Your palm should be facing the sky. Can you get the back of your wrist and forearm perfectly flat?
  4. Now, try to "cup" your wrist. You’ll feel the tray want to tip over and spill everything behind you. That weak, unstable feeling is what’s happening in your swing when you cup your wrist. The goal is to feel the solid, supportive structure of a flat wrist.

How to Fix Your Cupped Wrist: Practical Drills

Fixing a cupped wrist is about replacing an old habit with a new feeling. It takes repetition, but these drills are incredibly effective at teaching your hands and body what a powerful, flat-wrist position feels like.

Drill 1: The Handle Drag Takeaway

Often, cupping happens right at the start of the swing when a player incorrectly rolls the wrists open. This drill fixes that initial move.

  • Take your normal address position.
  • Begin your backswing by focusing on moving your hands, arms, and chest together as one unit.
  • The feeling you want is one of "dragging" the handle away from the ball, keeping the clubhead outside your hands until the club is parallel to the ground.
  • Pause at this waist-high position. The toe of the club should be pointing straight up at the sky, and the back of your lead wrist should be perfectly flat.
  • Repeat this takeaway rehearsal 10 times, focusing on that flat-wrist, toe-up checkpoint. This move sets the club on the right path and prevents the premature roll that leads to cupping.

Drill 2: The Motorcycle Rev

Sometimes, the best way to find neutral is to feel the opposite extreme. If you're stuck in extension (cupping), you need to feel flexion (bowing).

  • Take your club and make slow-motion backswings.
  • As you reach the top, consciously work on feeling like you're revving a motorcycle throttle with your lead hand. Your knuckles should feel like they are moving down towards the ground. This will put your wrist into a "bowed" position.
  • Start by hitting very small, 30-yard punch shots while trying to maintain this bowed feeling through impact. The ball will likely fly low and start to the left - that's okay! We are exaggerating to find the middle ground.
  • After hitting several shots with the motorcycle feel, try to go back to what you believe is a "flat" wrist position. It will now feel completely different, and you’ll have a much better awareness of what real extension (cupping) feels like.

Drill 3: The Business Card Drill

This drill provides direct tactile feedback, alerting you the moment your wrist starts to cup.

  • Tuck a business card, credit card, or small ruler under your golf glove so it lies flat against the back of your lead hand and wrist.
  • Make some half-swings. The goal is to keep the card resting flat and flush against your skin.
  • If you start to cup your wrist, the top edge of the card will press uncomfortably into the back of your forearm. This is instant feedback that you're making the wrong move.
  • Focus on making practice swings where you feel no pressure from the card. This encourages you to find that strong, flat position and maintain it.

Final Thoughts

A cupped lead wrist is a subtle but destructive habit that opens your clubface, causing inconsistent contact, slicing, and a significant loss of power. By understanding what it is and using video to identify it in your own motion, you can start building a new, more powerful position with targeted drills.
