The slice is golf’s most common fault — and for many golfers, its most demoralising. That banana-shaped shot curving helplessly to the right (for right-handed golfers) costs distance, accuracy, and confidence with every driver swing. The good news: the slice has a definitive mechanical cause, which means it has a definitive fix. This guide explains exactly why you’re slicing, what you need to change, and the specific drills that will ingrain those changes so the new swing pattern becomes automatic.
Why Golfers Slice: The Physics Explained
A slice is caused by two swing factors working in combination: an out-to-in swing path combined with a clubface that is open relative to that path at impact. The ball’s curvature is determined not by the swing path alone, but by the relationship between the path and where the face is pointing.
Here’s the physics: when the clubface is open relative to the swing path at impact, it imparts clockwise sidespin (for right-handed golfers). The ball initially launches somewhere between the face direction and the path direction, then curves strongly in the direction the face was pointing — to the right. The more open the face is relative to the path, the more dramatic the curve.
This is why simply “swinging more to the right” (trying to swing on a more in-to-out path) doesn’t fix a slice if the face remains open — you’ll just produce a push-fade or a blocked shot. The face and path must both be addressed.
The Most Common Causes of an Out-to-In Swing Path
1. The Over-the-Top Move
The most common swing fault causing a slice. At the transition from backswing to downswing, the shoulders “unwind” first and throw the club out away from the body, putting it on a steep, outside path that then cuts across the ball from outside-to-inside. This feels natural because the shoulders are the strongest muscles and most golfers instinctively try to use them to generate power — but in doing so, they destroy the swing path.
2. Poor Grip (Open Clubface)
A weak grip — where both hands are rotated too far to the left on the club — makes it structurally difficult to square the face at impact. Many slicers have both a poor path AND a weak grip, which is why the slice can feel so persistent and unfixable. If you can see only one knuckle on your left hand at address, your grip is likely too weak.
3. Ball Position Too Far Forward
With the driver, the ball is played off the inside of the lead heel. But many golfers play it even further forward — off the toe — which means the club is already past its natural impact position and moving on an inside-to-outside path when it reaches the ball. This exacerbates the open face problem.
4. Open Setup and Alignment
Many slicers set up open (body aligned left of target) as a subconscious compensation for the ball going right. But this open setup encourages an even more out-to-in swing path, perpetuating the problem. Check your alignment with alignment sticks regularly — what feels square is often dramatically open.
How to Fix a Slice: Step-by-Step
Step 1: Strengthen Your Grip
Before anything else, check your grip. Looking down at address, you should see 2–3 knuckles on your top (lead) hand. The “V” formed by your thumb and forefinger should point toward your trail shoulder. For the trail hand, the palm should face the target — not face upward (which weakens the grip and opens the face). A stronger grip makes it structurally easier to square the face through impact without manipulation.
Warning: a strengthened grip will initially feel very uncomfortable and may produce hooks or pulls as your brain adjusts. This is normal and temporary. Give the new grip at least 2–3 weeks of consistent practice before judging it.
Step 2: Fix Your Alignment
Place two alignment sticks on the ground at the range — one pointing at the target along the ball-target line, one parallel to it where your feet will be. Stand to the target-line stick and ensure your feet, hips, and shoulders are all parallel to the target. This is probably the simplest and most impactful change many slicers can make immediately.
Step 3: Work on the Transition
The over-the-top move originates at the transition from backswing to downswing. The fix is to initiate the downswing with the lower body — specifically by shifting the hips laterally toward the target and rotating them open — while the arms and club “drop” down into the slot. This sequence (lower body first, then arms, then club) is the hallmark of all great ball-strikers and the antidote to the over-the-top move.
4 Proven Drills to Fix a Slice
Drill 1: The Headcover Under the Armpit
Place a headcover or small towel under your trail armpit and keep it there throughout the backswing and first half of the downswing. If the headcover falls out, you’ve cast the club over the top. This drill forces the trail arm to stay connected to the body, which keeps the club on a better path. Hit 20 balls with the headcover in place, then 20 without — and notice the different ball flight.
Drill 2: The Gate Drill
Place two tee pegs in the ground: one on the inside-back of the ball (slightly behind it, closer to you) and one on the outside-front (slightly in front, further from you). The gate they create forces you to swing on an in-to-out path to avoid the inner tee and exit to the right of the outer tee. Even a few minutes with this drill creates powerful proprioceptive feedback about where your clubhead is travelling.
Drill 3: The Impact Bag Drill
An impact bag (a stuffed canvas bag) allows you to swing into the bag and freeze at impact to check your positions: Is the clubface square? Are your hips rotating through? Is your weight on the lead side? Many slicers discover at this point that their face is dramatically open at impact — a visceral feedback that verbal instruction rarely conveys as effectively.
Drill 4: The Right-Field Aim Drill
At the range, aim your body and clubface 30–40 yards to the right of your target (for right-handed golfers). Swing normally along your body line — in this case, to the right. What many slicers find is that this “feels” like a wildly rightward swing but produces shots that fly almost straight, because the exaggerated in-to-out path compensates for the habitual outside-to-inside pattern. This drill doesn’t create a permanent swing change but gives you the sensation of what a neutral path feels like from inside your own body.
Equipment Considerations for Slicers
While technique is the root cause, equipment can either help or exacerbate a slice. If you’re working on the swing changes above, these equipment adjustments can reduce the severity of the slice during the transition period:
- Driver loft: Higher loft (10.5° or 12°) reduces sidespin and produces a more forgiving ball flight for slicers. Lower-lofted drivers amplify sidespin.
- Draw-biased drivers: Many manufacturers offer draw-biased driver models (Callaway Paradym Draw, TaylorMade Stealth Draw) with an offset hosel that helps rotate the face to a squarer position at impact.
- Shaft flex: A shaft that is too stiff for your swing speed can leave the face open at impact. If you’re a moderate swing-speed player using a stiff shaft, try a regular flex.
- Grip size: Grips that are too thin make it easier for the hands to rotate the face open. Standard or slightly larger grip sizes can help maintain face angle through the hitting zone.
How Long Does It Take to Fix a Slice?
With consistent practice — ideally 20–30 minutes of deliberate drill work, 3–4 times per week — most golfers see meaningful improvement in ball flight within 2–4 weeks. A complete fix, where the new movement pattern is fully automated under on-course conditions, typically takes 6–12 weeks of deliberate practice.
The common mistake is practising the drills at the range until the ball flight improves, then immediately playing 18 holes and reverting to the old pattern under pressure. The course requires a different mental approach during this period: commit to the new swing feel even when results are temporarily inconsistent. The discomfort of the transition is the price of lasting improvement.

The Bottom Line
Fixing a slice requires addressing both the swing path and the clubface — not one or the other. Strengthen your grip, square your alignment, work on the lower-body-led transition, and commit to the four drills above. The slice is not a permanent condition or a sign that you lack talent — it’s a learnable, fixable mechanical pattern that millions of golfers have corrected by understanding the cause and applying the right remedies consistently.
