There's hardly a more demoralizing shot in golf than the duck hook - that low, screaming ball that seems to have a mind of its own as it veers violently to the left (for a right-handed golfer). It's a score-wrecker and a confidence-killer. This guide will help you understand precisely why this shot happens and provide you with actionable drills and a clear plan to stop that destructive hook for good.
What is a Duck Hook, Really?
Before we can fix it, we need to be crystal clear on what we're talking about. A duck hook is a specific type of errant shot. It typically starts either straight or even a little to the right of your target line before taking a dramatic, low-flying dive to the left. It's different from a "pull hook," which starts left of the target and curves even further left. The duck hook is particularly nasty because it often feels powerful off the face, but its flight is totally out of control, diving into trouble before you can even react.
In simple golf physics terms, a hook is created when the clubface is closed relative to the swing path at the moment of impact. A duck hook is what happens when this relationship becomes extreme. Your swing path is likely moving from "in-to-out," but your clubface is severely closed to that path. Think of it like this: the path gets the ball started to the right, but the severely shut face puts so much hook spin on the ball that it quickly corrects and dives left.
Diagnosing the Root Cause of Your Hook
Most duck hooks can be traced back to one (or a combination) of three primary faults in the swing. Let's go through a quick checkup to find your main culprit. Be honest with yourself as you review these common issues - the first step to a fix is a proper diagnosis.
Fault #1: A Grip That’s Too “Strong”
The term "strong grip" is one of the most misleading in golf. It doesn't mean you're squeezing the club too hard. It refers to how your hands are rotated on the club. Specifically for a hook, a grip that is "too strong" means your hands are rotated too far to the right (for a righty).
- Your top (left) hand might be turned so far over that you can see three or even four knuckles when you look down at address.
- Your bottom (right) hand is likely slid too far underneath the grip, with the palm facing up towards the sky.
This kind of grip presets the clubface in a closed or shut position. More importantly, it practically programs your hands to "release" or turn over aggressively through impact. Your body is just doing what feels natural based on how you're holding the club, and the result is a violently shut clubface.
The Fix: Find Your Neutral Grip
We need to weaken your grip into a more neutral position. It might feel strange at first - that's a good sign! It means you're changing something significant. You just have to trust it and give it some time.
- Top Hand Check: Place your left hand on the club. You should only be able to see the knuckles of your index and middle fingers. A good checkpoint is the "V" formed by your thumb and index finger, it should point roughly toward your right shoulder or chin.
- Bottom Hand Check: Now, bring your right hand to the club. The palm of your right hand should "cover" your left thumb. Resist the urge to slide it underneath. The "V" formed by your right thumb and index finger should also point generally toward your right shoulder.
- The Palm Test: Another great way to think about the right hand is that its palm should be facing the target, not the sky. When you set your right hand on the club, imagine you’re about to shake hands with the target.
Practice Drill: Repetitions without a ball. Get in your address posture and practice taking your new, neutral grip 20-30 times a day. Just let the club rest in front of you and work on placing your hands in the correct position. The more you do it, the quicker it will feel normal.
Fault #2: An “Out-of-Sync” Swing
This is a big one. Many duck hooks come from the arms and body getting "out of sync." This often happens when the lower body spins open too quickly at the start of the downswing. Your hips fire hard, but your arms and club get left behind, getting "stuck" deep behind your right hip.
From this stuck position, your very smart golf brain knows the clubface is wide open. So, what does it do? It signals your hands and forearms to flip over as fast as they can to try and square the face. This last-second, high-speed rotation is what slams the clubface shut and produces that hard hook spin. You feel powerful because you’re rotating so fast, but this isn't controlled power.
The Fix: Sync Your Arms and Chest
The goal is to feel your arms, hands, and chest all moving together and "arriving" at the ball at the same time. This prevents the arms from getting trapped and eliminates the need for that violent, last-second flip a the bottom.
Drill: The 9-to-3 Swing
- Take a short iron, like a 9-iron or 8-iron, and set up to a ball.
- Make a short backswing where your lead arm is parallel to the ground. This is the "9 o'clock" position. Focus on feeling your chest, arms, and club have all moved together as a single unit.
- Now, swing through to a follow-through where your trail arm is parallel to the ground, the "3 o'clock" position.
- The feeling you are looking for is that your chest faces the ball at impact and keeps turning through with your arms. You should feel that your arms are staying *in front* of your chest, not getting stuck behind it.
Start with very slow, deliberate swings, just chipping the ball 30-40 yards. Don't worry about distance. You're re-training a feeling. As you get more comfortable, you can build up the speed and length of the swing, but always maintain that sensation of your arms and torso working in unison through the hitting area.
Fault #3: Early Extension (Losing Your Posture)
Early extension is a swing flaw where your hips and pelvis move towards the golf ball during the downswing, instead of rotating. When you do this, you lose your setup posture, your spine angle straightens up too early, and you stand up out of the shot. We’ve all felt that one.
When you thrust your hips toward the ball, you effectively run out of room for your arms to swing freely. This does two very bad things that cause a hook:
- It forces your swing path excessively "in-to-out" because your arms are crowded.
- Since there is no room, your only option to get the club to the ball is, once again, to aggressively flip your hands and forearms right before impact
This combination - an excessively inside path and a rapidly closing clubface - is the perfect recipe for a duck hook.
The Fix: Keep Your Hips Back
The solution is to learn to rotate your hips while keeping your back side against an imaginary wall. You're not just turning, you are turning while maintaining your posture and spine angle.
The Chair Drill:
- Set up without a club, a few inches in front of a chair or your golf bag. Your backside should just be lightly touching it.
- Take a few practice backswings. You should feel your right glute (for a righty) press more firmly into the chair as you load your weight.
- Now for the feel of the downswing. As you rotate forward, the goal is to keep your backside touching the chair for as long as possible. The feeling you want is your left glute rotating back and around to touch the spot your right glute was just on.
- When done correctly, you'll feel an athletic separation where your hips are rotating open while your chest and shoulders stay down and in posture. You’ve created space for your arms to swing past your body.
Once you get this feeling, introduce a club and hit some small, soft shots while keeping your butt against the bag. This will build the motor pattern of rotating correctly instead of lunging at the ball.
Final Thoughts
Curing a duck hook once and for all boils down to matching up your clubface and your swing path. For most golfers, this means building a more neutral grip, learning to keep your arms and body in sync during the downswing, and maintaining your posture to create space. Start with the grip, then move on to the swing drills - slowly - and start building the confidence that your ball is going to fly straight.
