The slice is the most common miss in amateur golf, and it has probably cost club golfers more balls, more penalty drops and more quiet swearing than every other fault combined. If your ball starts roughly on line and then curves hard to the right (for a right-hander), often finishing in the trees or the next fairway over, you’re slicing it — and you’re in very good company.
The good news is that a slice is not a mystery. It’s caused by a specific, measurable relationship between your clubface and your swing path at impact, and once you understand that relationship, fixing it becomes a matter of practice rather than guesswork. This post covers what a slice actually is, the two real causes behind almost every one, and the drills and training aids that genuinely fix it.
What a slice actually is
A slice is a shot that curves significantly away from you in the air — left to right for a right-handed golfer. It’s different from a fade, which is the same shape but controlled and modest. A slice is the fade’s unruly cousin: too much curve, too little control, and usually a big loss of distance because the spin that bends the ball sideways also robs it of forward energy.
The ball curves because it’s spinning on a tilted axis, and that tilt comes from one thing only: at the moment of impact, your clubface was pointing to the right of the direction the club was travelling. That’s it. Every slice, without exception, comes down to that face-to-path relationship. Which means every slice fix has to address one of two things — the face, or the path.
Cause one: a clubface that’s open to your path
For most club golfers, the face is the bigger culprit — and the face is controlled overwhelmingly by your grip. A grip that’s too “weak” (hands rotated too far towards the target) makes it very difficult to square the face by impact without a deliberate, well-timed release. Under pressure, on the course, that timing disappears and the face stays open.
Check your grip right now: with your lead hand on the club, you should be able to see at least two knuckles when you look down. If you can only see one, or none, your grip is almost certainly contributing to your slice. Strengthening it — rotating both hands slightly away from the target — is the single fastest anti-slice change available, and it costs nothing.
Cause two: an out-to-in swing path
The second cause is the classic “over the top” move. The downswing starts with the shoulders and arms instead of the lower body, which throws the club outside the ideal line, and it then has to cut back across the ball — travelling left of target through impact while the face points right of the path. The result is that big banana curve, often starting left before slicing right.
Ironically, the slice itself teaches you to make this worse. Once you know the ball is going right, you instinctively aim further left — which encourages an even more out-to-in path, which creates even more slice spin. It’s a self-reinforcing loop, and it’s why slicers rarely fix themselves just by playing more golf. If this loop sounds familiar, it works much the same way as the casting fault we covered in why do I cast the golf club — an early, upper-body-led downswing is behind both.
Fix the face first: grip and setup
Always work on the face before the path. A strengthened grip and a square clubface will turn a huge slice into a manageable fade almost immediately, even if your path is still imperfect. Alongside the two-knuckle check, make sure the ball isn’t creeping too far forward in your stance with the driver, and that your shoulders aren’t aiming miles left at address — both are common slicer compensations.
If your grip has been weak for years, the correct position will feel strange for a couple of weeks. A moulded grip trainer is genuinely useful here because it puts your hands in the right place every single time without you having to think about it — we’ve covered the ones worth buying in our guide to the best grip trainers.
The drills that fix a slice
The gate drill. Lay one alignment stick on the ground pointing at your target, and push another into the ground (or lean it on a range basket) just outside the ball, angled away from you. To avoid hitting the outside stick, your club has to approach the ball from the inside — it makes an out-to-in path physically impossible. A pair of sticks is the cheapest training aid in golf, and this drill alone justifies them. Our best alignment aids guide covers the options.
The headcover drill. A gentler version of the same idea: place a headcover or rolled towel a few centimetres outside the ball. Swing without touching it. Miss the headcover, and your path is improving.
Slow-motion inside approach. Make continuous slow swings feeling the club drop to the inside as your lower body starts the downswing. Speed hides faults; slow motion exposes and retrains them. This pairs naturally with the tempo work in how to improve your golf swing tempo at home, because a rushed transition is what throws most golfers over the top in the first place.
Training aids that actually help
You don’t need a garage full of gadgets to fix a slice, but three categories genuinely earn their place: alignment sticks for the path drills above, a grip trainer to make the new hold automatic, and a weighted or flexible-shaft swing trainer to retrain the transition — the over-the-top move lives and dies in that first movement of the downswing. We’ve reviewed the options UK golfers can actually buy in our best swing trainers guide.
A simple anti-slice practice routine
- Minutes 1–5: grip checks in a mirror — two knuckles visible, club in the fingers, no death grip.
- Minutes 5–15: gate drill or headcover drill, half-speed swings, feeling the club approach from the inside.
- Minutes 15–20: full-speed swings alternating with slow-motion rehearsals, one swing thought only.
Do that three times a week — at the range or into a net at home — and most slicers see the ball flight change within a month. The curve softens into a fade first, then straightens. Don’t chase a draw immediately; a reliable fade is a perfectly good shot to play golf with.
Frequently Asked Questions
Why do I only slice my driver and not my irons?
The driver’s longer shaft and lower loft make it the most sensitive club in the bag to face-to-path errors. Your irons have enough loft and backspin to mask a mild slice pattern; the driver exposes it. If your driver slices and your irons fade gently, it’s the same fault — the driver is just telling the truth more loudly.
Should I just aim further left?
No — this is the compensation that makes slices worse. Aiming left encourages a more out-to-in path, which adds slice spin. Aim at your target, fix the grip, and train the path with the gate drill instead.
How long does it take to fix a slice?
Grip changes can soften a slice in a single session, though they feel odd for a fortnight. Path changes take longer — typically four to six weeks of regular, deliberate practice. The golfers who fail are almost always the ones who abandon the new grip because it feels strange, not the ones who lack talent.
Can I fix a slice practising at home without hitting balls?
Largely, yes. Grip work needs no ball at all, and slow-motion path rehearsals are arguably more effective without one because there’s no outcome to distract you. If you want ball flight feedback at home, a practice net changes everything — see how to practise your golf swing indoors for the full setup.
