A slice is one of the most frustrating and common problems in golf. Whether you’re hitting your driver, irons, or wedges, that left-curving shot (for right-handers) costs you distance, accuracy, and confidence. The good news? How to fix a slice in golf is learnable with the right drills, grip adjustments, and swing path corrections. This guide walks you through the causes of slicing, proven practice drills you can do today, and a complete swing improvement plan that works for every skill level.
Why You’re Slicing: Understanding the Root Causes
Before you can fix your slice, you need to understand why it happens. A slice is caused by excessive clubface opening relative to your swing path. In simpler terms: your club face is aimed too far right (for right-handers) while your swing path moves from outside-to-inside the target line. This combination creates sidespin that makes the ball curve away from your body.
The primary culprits are:
Weak Grip
Your grip has enormous influence on clubface control. A weak grip (where your hands are rotated too far toward your target) makes it nearly impossible to close the clubface through impact. To check your grip, look at your hands at address. You should see 2-3 knuckles on your lead hand. If you see fewer than 2, your grip is too weak and you’ll struggle to square the clubface.
Over-the-Top Swing Path
An “over-the-top” move happens when your upper body initiates the downswing instead of your lower body. Your shoulders rotate too early, causing your club to drop outside the target line. Combined with an open clubface, this creates the classic slice. Tour players have a slight out-to-in path, but with a closed clubface (creating draw spin). Slicers have the path without the face rotation—that’s the problem.
Alignment Issues
Many golfers stand too open at address (feet, hips, shoulders aimed left of target for right-handers). This encourages an outside-to-inside path and makes it harder to trust a solid swing. Poor alignment compounds every other issue.
Tension and Speed Loss
Slicers often grip the club too tightly, especially under pressure. This tension prevents proper wrist hinge and forearm rotation through impact, leaving the clubface open. Speed loss amplifies this—a slower swing with an open face is a guaranteed slice.
The Grip Fix: Your First Step to Stopping the Slice
Fixing your grip is the single most important change you can make. A stronger grip gives your forearms room to rotate and close the clubface at impact without forcing compensations elsewhere.
How to Build a Stronger Grip in 3 Steps
Step 1: Position your lead hand. Hold the club with your lead arm hanging naturally. Place the grip diagonally across your palm, from the base of your pinky finger to the middle knuckle of your index finger. Your thumb should sit slightly to the right of center (for right-handers). When you look down, you should see 2-3 knuckles of your lead hand.
Step 2: Add your trail hand. Rest your trail hand below your lead hand with the palm facing your target. Your trail hand’s lifeline should sit on top of your lead thumb. The handle should run diagonally across your trail hand from the middle knuckle to the base of your pinky.
Step 3: Create a unified grip. Your thumbs should point slightly right of center. Your trail pinky can overlap or interlock with your lead index finger (choose whichever feels more secure). Check that your hands work as one unit—no gaps or loose fingers.
Practice this grip 50 times a week without swinging. Just hold it, check it, and feel it. Muscle memory builds through repetition, not just full swings.
The Alignment Drill: Stop Your Over-the-Top Move
Proper alignment prevents your shoulders from rotating too early (the over-the-top move). Use this two-step process:
The Step-Behind Drill: Place two alignment sticks on the ground—one along your target line and one along your toe line, about 3-4 inches left of the target line (for right-handers). Stand behind the ball and step into your stance using the sticks as guides. Your feet, hips, and shoulders should all be parallel to the sticks, not closed or open. Spend 10 minutes doing this with every club in your bag. Your brain will reprogram what “square” feels like.
The Mirror Drill: Practice your setup in front of a mirror with a golf shaft or alignment stick across your shoulders. Watch that your shoulder line stays parallel to your target line at address. Many slicers automatically close their shoulders, which triggers an over-the-top move. The mirror shows you instantly whether you’re doing it.
Three Essential Drills to Rebuild Your Swing Path
Drill 1: The Downplane Drill (Fix Over-the-Top)
Place a PVC pipe or alignment stick along the ground pointing at your target. This is your “plane.” Position another stick along your back foot, pointing at a 45-degree angle away from the target. During your backswing, your club should stay inside this 45-degree line. On the downswing, your hands should stay inside the line until you reach waist height. If your hands come outside this line early, you’re going over-the-top.
Hit 20 shots focusing only on keeping your hands inside the plane on the way down. You’ll feel the difference immediately—better contact, more distance, and straighter shots.
Drill 2: The Pump Drill (Feel the Lag and Rotation)
Address a ball and take your backswing. At the top, pump down 6 inches without hitting the ball. Feel your lower body driving toward the target while your shoulders stay back. Pump down 2-3 times, then complete the swing. This drill builds the sequencing that prevents over-the-top. Your lower body leads, not your shoulders. Do this for 5 minutes before every practice session—it retrains your transition.
Drill 3: The Towel Drill (Feel the Lag and Forearm Rotation)
Place a small towel under your lead armpit and hold it there with pressure. Make 50 half-swings without the towel falling. This teaches you to maintain lag and prevent early wrist extension. Without lag, the clubface opens too early and you slice. With lag, your forearms have time to rotate and square the face at impact. When you transition to full swings, the towel sensation stays—your lead arm stays close to your body, and your forearms rotate.
Your Weekly Practice Plan to Stop Slicing
Consistency beats intensity. Spend 45 minutes 3-4 times per week on this plan. Avoid the range trap—hitting 100 balls with the same slice doesn’t fix anything.
Minutes 1-10: Grip Work and Alignment. Build your new grip 20 times, checking it each time. Spend 5 minutes on the mirror or alignment stick drill. Groove the feeling of being square.
Minutes 11-20: Downplane Drill. Use alignment sticks and hit 20 balls focusing only on keeping your hands inside your plane on the downswing. This is your most critical technical fix.
Minutes 21-30: Pump Drill and Towel Drill. 5 minutes of pump drill work (lower body leading), then 10 minutes of towel drills to ingrain lag and rotation.
Minutes 31-45: Free Swings. Hit balls with your new setup, grip, and awareness. Don’t over-think—just trust the work you’ve done. Finish with 3-4 shots visualizing a straight shot down the middle.
When to Seek Professional Help
If you’re still slicing after 4 weeks of consistent practice, book a lesson with a PGA professional. You may have a swing issue that’s unique to your motion—every golfer has individual quirks. A pro can use video analysis and launch monitor data to pinpoint exactly what’s happening.

Senior golfers can also find targeted advice in our golf tips for seniors.
Final Takeaway: Your Path to Straight Drives
Fixing a slice takes patience, but the process is predictable. Strengthen your grip, fix your alignment, correct your swing path, and practice the drills. Within 2-3 weeks of consistent work, you’ll notice shots flying straighter and longer. The slice isn’t a death sentence—it’s a fixable problem with the right approach. Commit to the plan, trust the process, and enjoy the satisfaction of hitting straight shots again.
