To fix a slice, you need to get the clubface square to your swing path at impact. For most golfers that means three changes: a slightly stronger grip, square alignment at address, and a swing path that approaches the ball from inside the target line instead of from outside it. Fix your setup first, then use the drills below for a few weeks until the new pattern holds.
This guide is written for right-handed golfers (a slice curves to the right). If you are left-handed, flip every direction.
What Causes a Slice?
A slice happens when the clubface is open relative to your swing path at impact. The ball picks up sidespin and curves hard to the right, usually losing distance as it goes.
The most common pattern is an open face combined with an out-to-in path: the club travels across the ball from outside the target line, often called "coming over the top." Golfers who aim left to compensate for the slice usually make the path even more out-to-in, which makes the curve worse.
Typical root causes include:
- A weak grip that makes it hard to square the face.
- Shoulders and feet aimed left of the target.
- Ball position too far forward, which pulls the shoulders open.
- Starting the downswing with the upper body instead of the lower body.
- Not rotating the forearms through impact, so the face stays open.
Read Your Ball Flight
Your ball flight tells you what to fix. As a general rule, the clubface has the biggest influence on where the ball starts, and the relationship between face and path decides how much it curves.
| Ball flight | Likely cause | First fix to try |
|---|---|---|
| Starts left, curves right (pull-slice) | Out-to-in path, face open to path | Path drills (headcover, gate) |
| Starts straight, curves right | Face open to a fairly neutral path | Grip check, release drills |
| Starts right, keeps curving right (push-slice) | Face open at impact | Stronger grip, forearm rotation |
| Weak, high fade with driver only | Steep, glancing strike on the driver | Tee height and ball position |
Step 1: Fix Your Setup First
Many slices are built before the club ever moves. Spend your first session on these four checks, using an alignment stick or a club on the ground.
- Strengthen your grip. Rotate your lead hand (left hand) slightly away from the target until you can see two to three knuckles when you look down. The "V" between your trail-hand thumb and index finger should point toward your trail shoulder.
- Square your alignment. Lay one stick on the target line and a second parallel to it at your toes. Check that your feet, hips and shoulders are parallel to that stick, not aimed left.
- Check ball position. Mid-irons go roughly in the center of your stance, moving forward as the club gets longer. Driver sits inside your lead heel. If the ball creeps too far forward, your shoulders open to reach it.
- Set your trail side lower. At address, let your trail shoulder sit a little lower than your lead shoulder. This helps the club approach from the inside.
Hit 10 balls with a 7-iron after each change and note the curve. A new grip will feel strange at first; give it at least a few sessions before judging it.
Step 2: Drills to Fix a Slice
Once the setup is sound, train a better path and face. Use a 7-iron or 8-iron, half to three-quarter swings, and a specific target for every ball.
- Headcover drill (path). Place a headcover about 6 inches outside and slightly behind the ball. If you come over the top, you will hit it. Make 15 swings without touching it, then 5 full shots.
- Gate drill (path). Push two tees into the ground to form a gate just wider than your clubhead, angled slightly right of your target line. Swing through the gate without hitting a tee. Do 3 sets of 10.
- Closed-stance drill (path). Drop your trail foot back a few inches so your stance is closed. This encourages an in-to-out swing. Hit 10 balls and try to make each one start right and curve back toward the target.
- Toe-up to toe-up (release). Make waist-high swings where the toe of the club points to the sky halfway back and again halfway through. This trains the forearm rotation that closes the face. Do 20 slow reps.
- Split-hand drill (release). Grip the club with your hands a few inches apart and make half swings. You will feel the trail hand rolling over the lead hand through impact. Do 10 reps, then hit 5 balls with a normal grip.
- Feet-together drill (sequence). Hit three-quarter shots with your feet touching. It is hard to lunge with the upper body this way, so it helps you rotate instead of throwing the club outward. Hit 10 balls.

Step 3: How to Fix a Slice With Your Driver
Many golfers hit irons fairly straight but slice the driver, because the longer shaft and lower loft exaggerate an open face. Add these driver-specific checks:
- Tee it higher. About half the ball should sit above the top of the driver head. A higher tee encourages an upward, shallower strike.
- Move the ball forward and tilt. Play the ball inside your lead heel and tilt your spine slightly away from the target so your head stays behind the ball.
- Swing at 80%. Swinging harder usually makes the upper body take over. Hit 10 drives at a smooth tempo and aim for the center of the fairway.
- Use an intermediate target. Pick a spot a few feet in front of the ball on your target line and align the clubface to it before setting your feet.
- Check your equipment. Loft, shaft and lie angle all affect face control. If you still slice after weeks of good practice, a club fitting can show whether your gear is part of the problem.
A 4-Week Slice-Fix Practice Plan
Two or three focused sessions a week, about 45 to 60 minutes each, is enough to start changing the pattern. Keep a simple note of how many balls curved right in each session.
| Week | Focus | Session plan | Goal |
|---|---|---|---|
| 1 | Setup | Grip and alignment checks, 50 half swings with a 7-iron, toe-up to toe-up drill | New grip feels repeatable |
| 2 | Path | Headcover and gate drills, 3 sets of 10, then 20 full 7-iron shots | Miss the headcover on 15 of 15 swings |
| 3 | Release | Split-hand and closed-stance drills, then 30 shots alternating 7-iron and 5-iron | Most shots start on line or slightly right |
| 4 | Driver and transfer | Driver checks, 20 drives at 80%, then play 9 simulated holes | Keep the slice fix under on-course pressure |

How to Fix Your Slice Indoors, Year-Round
A slice fix needs honest feedback on every swing. Indoors, you get that feedback in any weather and at any time of year.
At Edge Golf in Edgewater, NJ, every bay uses a Golfzon simulator that shows shot data on every swing, including carry, direction and shot shape. You can see immediately whether a shot started left and curved right, or whether a drill actually straightened the flight.
- Auto tee: the next ball sets itself, so you can run drill sets without breaking your setup.
- Moving floor: practice your new swing from uphill, downhill and sidehill lies, where slices often get worse.
- 300+ courses: test the fix on real holes during Week 4 of the plan.
- PGA-certified instructors: a private or group lesson can pinpoint whether your slice is mostly face, path or setup.
Practice bays are priced per bay per hour, not per person (general rate $40/hour; VIP members pay less). We are open from 8 AM daily, until 10 PM Sunday to Thursday and 11 PM Friday and Saturday. Walk-ins are welcome, and you can book a bay online to skip the wait. We are at 18 Edgewater Towne Center, next to Fort Lee and a short drive from the George Washington Bridge.
Common Mistakes When Fixing a Slice
- Aiming further left. It feels like a fix, but it reinforces the out-to-in path.
- Changing everything at once. Work in order: setup, path, release, then driver.
- Only hitting driver. Learn the pattern with a 7-iron first, where the curve is smaller and easier to read.
- Quitting the new grip too early. A stronger grip may produce a few hooks at first. That usually means the face is finally closing.
- No feedback. Without seeing start direction and curve, you are guessing. Track every shot.
Frequently Asked Questions
What is the fastest way to fix a slice?
Start with your setup: strengthen your grip so you can see two to three knuckles on your lead hand, and make sure your feet and shoulders are aimed parallel to the target line. These changes often reduce the curve within one session. Then add path drills like the headcover drill to make the fix last.
Why do I slice my driver but not my irons?
The driver has the longest shaft and the least loft, so an open clubface produces more sidespin and a bigger curve. Teeing the ball higher, playing it inside your lead heel and swinging at a smoother tempo usually help. If the slice persists, a club fitting can check whether your driver suits your swing.
Does a stronger grip fix a slice?
A stronger grip makes it easier to return the clubface square or slightly closed at impact, which is why it is one of the most common slice fixes. It will not fix an out-to-in swing path on its own. Combine it with alignment checks and path drills.
How long does it take to fix a slice?
It depends on how ingrained the pattern is and how often you practice. Many golfers see a noticeable change within a few weeks of two or three focused sessions per week. Expect the old pattern to return under pressure at first, which is why on-course or simulated play is part of the plan.
Can I fix my slice on a golf simulator?
Yes. A simulator shows start direction, curve and shot shape on every swing, which is exactly the feedback you need. At Edge Golf, Golfzon bays display shot data after each shot, and you can test your fix on full simulated courses.
Should I take a lesson to fix my slice?
A lesson is a good idea if setup changes and drills have not helped after a few weeks. An instructor can see whether the main cause is your grip, path or sequence and give you one priority to work on. Edge Golf offers private and group lessons with PGA-certified instructors.
A slice is one of the most common faults in golf, and one of the most fixable. Square up your setup, train the path and release with short, specific drills, and check every shot's start line and curve. Stick with the 4-week plan and you will start seeing straighter, longer shots.
