The slice is the most common miss in golf. It curves dramatically from left to right for right-handed golfers, costs distance, and makes course management a constant battle against one side of the fairway. If you have been fighting a slice, you are not alone — an estimated 70 to 80% of amateur golfers struggle with some version of this shot pattern. The encouraging news is that a slice is fixable. It has identifiable, mechanical causes, and with the right drills and understanding, you can eliminate it.
In this guide, you will learn exactly what causes a slice, how to diagnose which type you have, and specific drills to fix the root cause rather than just compensating for the symptom. If you are also looking to add distance alongside straighter shots, our guide on increasing driver distance addresses the power side of the equation.
What Causes a Slice
A slice results from one thing: an open clubface relative to the swing path at impact. That is the entire story. The ball curves because sidespin is imparted when the clubface and swing path are misaligned. If the face is open (pointing right of the path for a right-hander) at impact, the ball spins clockwise and curves right.
However, the reasons the clubface is open can vary. For some golfers, the face is open because their grip is too weak (rotated too far to the left). For others, the face opens during the backswing due to excessive forearm rotation or a cupped left wrist at the top. For many, the face is open because the swing path is severely outside-to-in (cutting across the ball), which makes even a square face appear open relative to the path. Understanding your specific cause is essential — the fix for a grip issue is different from the fix for a path issue.
Diagnosing Your Slice
The Pull-Slice
The ball starts left of your target and then curves hard to the right. This is the most common slice pattern and indicates an outside-to-in swing path with an open clubface relative to the path. The ball starts left because the path is aimed left; it curves right because the face is open to that path. If this is your pattern, the primary fix is correcting your swing path (see drills below).
The Push-Slice
The ball starts right of your target and then curves further right. This indicates a swing path that is slightly inside-to-out or neutral, but with a clubface that is significantly open. Your path is actually decent — the problem is purely face angle. If this is your pattern, focus on grip and face control fixes first.
The Straight-Slice
The ball starts roughly on target and then curves right. This means your swing path is close to your target line, but the face is slightly open. This is the easiest slice to fix because your path is good — you just need minor adjustments to close the face a few degrees at impact.
Fix 1: Strengthen Your Grip
The grip is the single most overlooked cause of a slice, and it is the easiest fix. A weak grip — where both hands are rotated too far toward the target — makes it physically difficult to close the clubface through impact. To strengthen your grip, rotate both hands slightly away from the target (clockwise for right-handers) on the club. You should see two to three knuckles on your left hand when you look down at address. The V formed by the thumb and index finger of each hand should point toward your right shoulder, not your chin.
This change will feel dramatic at first. Many slicers who strengthen their grip are shocked to see the ball go left for the first few shots. That is normal — it means the face is now closing, which is exactly what you want. Your brain will quickly recalibrate, and within a bucket of balls, you will start hitting straighter shots with less effort.
Fix 2: Correct Your Swing Path
An outside-to-in swing path is the most common contributor to the pull-slice. It typically starts with an over-the-top move in the downswing — the shoulders fire first, throwing the club outside the intended swing plane. The result is a cutting motion across the ball from outside to inside.
To fix this, you need to feel the club dropping to the inside during the transition from backswing to downswing. One effective drill: place a headcover or small towel just outside and behind the ball, about two inches away. If your path is outside-to-in, you will hit the headcover. Practice making swings that miss the headcover to the inside, forcing your club to approach from inside the target line.
Another powerful path drill is the step-through drill. Set up normally, but as you start your downswing, step your left foot toward the target before swinging through. This forces your lower body to lead the downswing and prevents the upper body from spinning open prematurely. It feels awkward at first, but it quickly trains the correct sequencing.
Fix 3: Close the Face Through Impact
Even with a good grip and a good path, some golfers struggle to release the club through impact. The forearms should rotate naturally through the hitting zone, with the right forearm crossing over the left (for right-handers) after impact. If you hold the face open through impact — sometimes called hanging on or blocking — the ball will fade or slice.
Practice the split-hand drill: grip the club with a one-inch gap between your hands. Make slow, half swings, focusing on the feeling of your right hand rotating over your left through impact. The split grip exaggerates the release and teaches your hands to work together through the hitting zone. Do 20 to 30 repetitions, then close the gap back to your normal grip and hit full shots.
Fix 4: Address Your Setup
Sometimes the slice is built into your setup before you even swing. Check these common alignment errors: shoulders aimed left of the target (this promotes an outside-to-in path), ball position too far forward (which delays the face from closing), and the clubface open at address (which requires perfect timing to square up). Set up with your feet, hips, and shoulders parallel to the target line — use alignment sticks on the range to verify this, as most golfers are not aligned where they think they are.
Also check your ball position. For a driver, the ball should be just inside your left heel. For irons, it should be in the center to just forward of center. A ball that is too far forward gives the clubface more time to open before reaching the ball, compounding a slice tendency.
Range Practice Plan for Slice Correction
Dedicate two to three range sessions per week to slice correction using this structure. Start with 10 minutes of grip check and slow-motion swings focusing on hand and forearm rotation. Spend 15 minutes on the headcover path drill with a 7-iron, hitting half shots at 60% speed. Progress to full swings for 15 minutes, focusing on one key feeling — the club dropping to the inside on the downswing. Finish with 10 minutes of on-course simulation: change targets with every shot and use your full pre-shot routine to transfer the range work to realistic conditions.
Be patient. Changing an ingrained swing path takes time — typically four to six weeks of consistent practice before the new pattern becomes reliable under pressure. You may go through a phase where you hook the ball (curving left), which actually means the fix is working and you have overcorrected slightly. That is easier to fine-tune than a slice. For more on developing your overall game, a solid pre-shot routine will help you take your range improvements onto the course, and understanding course management strategy will help you play smarter even while you are fixing your ball flight.
A slice is not a life sentence. It is a mechanical pattern with mechanical solutions. Fix your grip first — it is the quickest win. Then address your path. Then refine your release. Stack these corrections progressively, practice with purpose, and your slice will become a thing of the past.
