The slice is the most common miss in golf. It’s the banana-shaped, left-to-right ball flight (for right-handed golfers) that robs you of distance, accuracy, and confidence off the tee. But here’s the encouraging truth: a slice is caused by a predictable set of mechanical errors, and every one of them can be fixed with the right understanding and targeted practice. You don’t need to overhaul your entire swing — you need to address the specific cause of your slice, and there are only a few possibilities.
In this guide, we’ll break down exactly what causes a slice, help you diagnose which type you’re hitting, and give you specific drills you can take to the range today to start straightening your ball flight.
What Causes a Slice
Every slice in golf is caused by the same fundamental physics: the clubface is open relative to the swing path at impact. That’s it. When the face points to the right of the direction the club is moving through the ball, it imparts clockwise sidespin (for a right-handed golfer), which curves the ball to the right.
Understanding this relationship between face and path is the key to fixing your slice. There are two variables you can change: the path (the direction the club travels through impact) and the face (where the clubface points at impact). Most slicers have an out-to-in swing path (the club cuts across the ball from outside the target line to inside it) combined with a clubface that’s open to the target. This produces a shot that starts left and curves dramatically right — the classic pull-slice.
Three Types of Slice and How to Identify Yours
The Pull-Slice
The ball starts left of your target and then curves sharply to the right, finishing well right of where you aimed. This is the most common type and indicates a significantly out-to-in path with a face that’s open to the path but closed to the target at the start. The fix involves addressing the path first — getting the club to approach the ball more from the inside.
The Straight Slice
The ball starts roughly on your target line and then curves to the right. This means your path is roughly neutral (neither out-to-in nor in-to-out), but the face is open at impact. The fix is primarily a face issue — improving your grip, forearm rotation, or both.
The Push-Slice
The ball starts right of your target and curves further right. This indicates an in-to-out path (which is actually desirable) with a face that’s severely open to both the path and the target. The path is fine — the fix is entirely about closing the face. This is often the stage golfers reach when they’ve successfully changed their path but haven’t yet matched the face to it.
Fix 1: Check Your Grip
A weak grip is the number-one cause of an open clubface and the easiest fix to implement. When we say “weak” in golf, we don’t mean your grip pressure — we mean the rotational position of your hands on the club.
Hold the club in front of you and look down at your left hand (for right-handed golfers). You should be able to see at least two, ideally two and a half, knuckles of your left hand. If you can only see one knuckle, your grip is too weak — the hand is rotated too far to the left on the handle, which makes it nearly impossible for the face to square up through impact without a compensating manipulation.
To strengthen your grip, rotate your left hand clockwise on the handle until you see those two to three knuckles. Then place your right hand so the lifeline of the right palm covers the left thumb, with the right-hand V (formed by the thumb and forefinger) pointing toward your right shoulder. This neutral-to-strong grip positions your hands to naturally return the face to square through the hitting zone.
Drill — The Grip Check: Before every practice session and every round, hold the club at address and verify your knuckle count. Take five practice swings with an exaggerated strong grip (four knuckles visible) to feel how the clubface closes more easily. Then dial it back to your two-and-a-half knuckle position. This recalibration takes 30 seconds and can fix a slice immediately.

Fix 2: Correct Your Swing Path
If your grip is already adequate, the next suspect is your swing path. An out-to-in path — where the club approaches the ball from outside the target line and cuts across it — is the hallmark of most slicers. This “over-the-top” move typically starts in the transition from backswing to downswing, when the upper body fires first and throws the hands and club outward.
The fix is to learn to start the downswing from the ground up. Your lower body initiates the transition — the left hip shifts toward the target and begins to rotate, which drops the hands and club into a shallower, more inside path. Think of it as the hands falling toward your right hip pocket before the club swings out toward the ball.
Drill — The Headcover Gate: Place a headcover or small towel about 6 inches outside the ball and a few inches behind it (toward your back foot). If your path is out-to-in, you’ll hit the headcover on your downswing. Practice making slow, three-quarter swings that avoid the headcover — this forces your club to approach from inside the line. Start without a ball, then progress to hitting balls at 50 percent speed. Once you can consistently miss the headcover, your path is improving.
Drill — The Inside Tee: Place a tee in the ground about 3 inches inside and 3 inches behind the ball (toward your right foot for right-handers). Your goal is to feel like you’re swinging at the inside tee rather than the ball. This promotes an in-to-out path and fights the natural tendency to cut across the ball. Hit 20 balls focusing on clipping the inside tee, and you’ll feel the difference in path immediately.
Fix 3: Improve Your Body Rotation
Many slicers stall their body rotation through impact and rely on their arms to flip the club at the ball. When the body stops turning, the arms and club have to swing across the body (out-to-in) because there’s nowhere else for them to go. The result is a slice.
In a good golf swing, the body continues rotating toward the target through and beyond impact. Your belt buckle should face the target at the finish, and your weight should be fully on your left foot. This continuous rotation gives the arms space to swing from inside and allows the club to release naturally.
Drill — The Continuous Turn: Take your address position and make swings focused exclusively on turning your chest to face the target. Don’t worry about the ball — just feel the sensation of your body rotating through impact without stopping. Your arms will follow. After 10 body-rotation swings, hit some balls and try to maintain the same feeling of continuous turning. Your finish position should feel balanced, with your chest facing the target and your weight stacked over your left leg.
Fix 4: Address Your Alignment
Here’s a hidden cause of the slice that catches many golfers off guard: aiming too far right. When you aim right (often subconsciously, to compensate for the slice), your brain knows the ball needs to go left of where you’re aimed, so it instinctively pulls the swing path to the left — creating the very out-to-in path that causes the slice. It’s a vicious cycle.
Check your alignment by placing a club or alignment stick on the ground parallel to your target line, just outside the ball. Your feet, hips, and shoulders should be parallel to this stick, not aimed right of the target. Many golfers are shocked to discover how far right they’ve been aiming.
Drill — The Alignment Station: On the range, set up two alignment sticks — one along your target line and one along your foot line, parallel to each other. Hit 20 balls while checking that your shoulders are parallel to the sticks before every swing. Once your alignment is square, the subconscious compensation disappears, and your natural swing path often straightens out on its own.
Fix 5: Strengthen Your Release
The “release” is the rotation of the forearms and the squaring of the clubface through impact. Slicers often hold off the release, keeping the face open through the hitting zone because they’ve learned (subconsciously) that releasing the club sends the ball left. But that’s only true when the path is out-to-in. With a corrected path, releasing the club is exactly what produces straight shots and gentle draws.
Drill — The Toe-Over-Heel: Using a 7-iron, make half swings and focus on the toe of the club passing over the heel through impact. You should feel your right forearm rotate over your left (for right-handers) in the follow-through. Hit 20 balls with this exaggerated release. The shots will likely hook at first — that’s perfect. You’re teaching your hands what it feels like to close the face, and from there, you can dial it back to straight.
Drill — The Glove Under the Arm: Tuck a glove or small towel under your right armpit and hit half-shots without letting it drop. This keeps your right elbow connected to your body, which promotes an inside path and makes it much easier for the club to release naturally. If the glove falls out, your right elbow is flying away from your body — a common slice trigger.
A Practice Plan for Fixing Your Slice
Fixing a slice doesn’t happen in one range session. Give yourself four weeks of focused practice, three sessions per week, using this progression.
Week 1: Focus exclusively on grip. Strengthen your grip to the two-and-a-half knuckle position and hit 50 balls per session with the new grip. Don’t worry about where the ball goes — just get comfortable with the hand position. Practice the Grip Check before every session.
Week 2: Add the Headcover Gate and Inside Tee drills. Hit 30 balls with each drill, focusing on feeling the club approach from inside the target line. Continue with the strengthened grip from Week 1.
Week 3: Introduce the Continuous Turn and Alignment Station drills. By now, your grip and path should be improving, and adding body rotation and proper alignment will tie the pieces together. Hit 15-20 balls with each drill, then hit 20 balls trying to combine everything.
Week 4: Integration week. Warm up with one drill from each category (grip, path, rotation), then hit 40-50 balls with a full swing, focusing on one thought only: turning through the ball. Play a round by the end of the week and observe the results. You may still slice occasionally under pressure — that’s normal. The new pattern needs reps to become automatic.
If you’re working on your overall swing mechanics alongside fixing the slice, our article on consistent iron striking covers the fundamentals of ball-first contact that apply to every club in your bag. And for insights on what even tour professionals get wrong with their swing mechanics, our analysis of Scottie Scheffler’s iron play struggles shows that even the best in the world constantly refine these same fundamentals.
A warm-up routine before your practice sessions and rounds also helps establish good movement patterns. Our pre-round warm-up guide gives you a structured approach that primes your body for the swing changes you’re working on.
The slice is a fixable problem. It feels permanent because it’s been your miss for years, but the underlying mechanics are simple and the drills work quickly once you commit to them. Four weeks of focused practice can turn a 30-yard slice into a five-yard fade — or even a gentle draw. Your drives will go further, your accuracy will improve dramatically, and your confidence on the tee will transform how you approach every hole.
