The slice is the most common miss in golf. Studies from launch monitor data estimate that over 70 percent of amateur golfers slice the ball, and it costs the average player 20 to 40 yards of distance and any hope of consistent accuracy off the tee. The frustrating part is that most slicers know they slice — they just cannot figure out how to stop. This guide breaks down the exact mechanics that cause a slice, gives you a clear diagnostic framework to identify your specific cause, and provides targeted drills that address each one. If you commit to this process, you can fix your slice — permanently.
What Actually Causes a Slice
A slice happens when the clubface is open relative to the swing path at impact. That is it. Every slice, from a gentle fade to a banana ball that ends up two fairways over, comes down to this single relationship: face angle versus path direction.
When the clubface points to the right of the path (for a right-handed golfer), it imparts clockwise sidespin on the ball. The more open the face relative to the path, the more sidespin, and the more the ball curves. A face that is 5 degrees open to the path produces a manageable fade. A face that is 10 to 15 degrees open produces the dramatic curve most slicers experience.
Understanding this relationship is critical because it means there are only two ways to fix a slice: close the face, change the path, or (ideally) both. Every drill and tip in this guide targets one or both of these variables.
The Three Root Causes of a Slice
While the face-path relationship is the physics of a slice, the underlying causes are mechanical. Most slices come from one or more of these three root causes.
1. An Open Clubface at Impact
The clubface is responsible for roughly 75 percent of the ball’s starting direction, according to research by Dr. Robert Neal using TrackMan data. If your clubface is open at impact, the ball starts right and curves further right. Common reasons the face stays open include a weak grip (hands rotated too far to the left on the club), poor wrist mechanics during the downswing (the lead wrist cupping rather than bowing), and a lack of forearm rotation through impact.
2. An Over-the-Top Swing Path
An over-the-top swing path moves from outside the target line to inside it through impact — creating a left-to-right cut across the ball. Even if the clubface is square to the target, an out-to-in path produces a fade or slice because the face is open relative to the path. The most common cause of an over-the-top move is initiating the downswing with the upper body (shoulders and arms) rather than the lower body (hips and legs). This throws the club outward instead of dropping it into the slot on the inside.
3. Poor Setup and Alignment
Many slicers unknowingly set up in a way that makes a slice inevitable. Aiming left to compensate for the expected curve actually worsens the problem — it encourages an even more out-to-in path. Ball position too far forward promotes an open face at impact. Standing too far from the ball forces an upright swing plane that tends to come over the top. Before changing anything in your swing, check your setup — it might be the only thing that needs fixing.
Step 1: Fix Your Grip
The grip is the foundation of face control. A neutral or slightly strong grip makes it dramatically easier to square the clubface at impact.
Hold the club in your lead hand (left hand for right-handed golfers) with the handle running diagonally across the fingers, from the base of the index finger to the pad below the pinky. When you look down, you should see two to three knuckles on the back of your lead hand. If you can only see one knuckle, your grip is too weak and the face will tend to stay open.
Place your trail hand (right hand) so that the lifeline of the palm covers the lead hand’s thumb. The V formed by the trail hand’s thumb and index finger should point toward your trail shoulder. If it points at your chin or lead shoulder, the grip is too weak.
Drill: The Grip Check. Before every practice session, set up to a ball and look down at your grip. Count the knuckles on your lead hand. If you see fewer than two, rotate both hands slightly clockwise (for a righty) until you see two to three. Hit 20 balls with this adjusted grip and notice how the ball flight changes. For most slicers, this single change reduces the slice by 30 to 50 percent immediately.
Step 2: Square the Clubface Earlier
Even with a good grip, many slicers fail to rotate the clubface closed through impact. The lead wrist needs to be flat or slightly bowed (flexed) at impact — not cupped (extended). A cupped lead wrist opens the face.
Drill: The Glove Under the Watch. Slide a golf glove or small towel under your watch or wristband on your lead arm. During practice swings, focus on pressing the back of your lead wrist flat against the glove through impact. The physical feedback helps you feel the flat wrist position that squares the face. Hit 30 balls focused on this feeling.
Drill: The Toe-Up to Toe-Up. Take half swings where the club goes from toe-up at hip height on the backswing to toe-up at hip height on the follow-through. This ensures the forearms are rotating properly through impact. If the face stays pointing at the sky through impact, you are not rotating enough. This drill helps you feel the correct release pattern without overthinking it.
Step 3: Fix the Swing Path
Once the face is closer to square, address the path. The goal is to shift from out-to-in to neutral or slightly in-to-out.
Drill: The Headcover Gate. Place a headcover or small towel approximately one club-head width outside the ball, just behind it (closer to you). If your downswing is over the top, the club will hit the headcover. The visual and physical barrier trains you to drop the club to the inside on the downswing. Practice hitting balls without disturbing the headcover until the inside path feels natural.
Drill: The Step-Through. Set up normally, then on the downswing, physically step your lead foot toward the target as you swing through. This forces your hips to lead the downswing instead of your shoulders, which naturally shallows the club path and prevents the over-the-top move. It feels exaggerated at first, but the movement pattern transfers to your normal swing over time.
Drill: Trail Elbow to Hip. On the downswing, focus on driving your trail elbow toward your trail hip before anything else moves. This drops the club into the slot on the inside of the target line and prevents the outward casting motion that creates an over-the-top path. Feel as if your right elbow (for a righty) is almost brushing your right hip on the way down. Pair this with the path work from our guide to hitting irons consistently for a comprehensive swing improvement plan.
Step 4: Check Your Setup
Revisit your alignment and ball position after making grip and swing changes. With the new, more neutral ball flight, you no longer need to aim left. Set up with your feet, hips, and shoulders parallel to the target line. Place the ball just inside your lead heel for the driver and progressively further back in the stance for shorter clubs. Use alignment sticks on the ground during every practice session to confirm your alignment — your eyes are unreliable judges of where you are actually aimed.
A 30-Day Practice Plan to Fix Your Slice
Week 1: Grip and face control. Every session, start with the grip check. Hit 50 balls focused on seeing two to three knuckles and feeling a flat lead wrist at impact. Use the Toe-Up to Toe-Up drill for the first 20 balls as a warm-up.
Week 2: Add path work. Set up the Headcover Gate drill and hit 40 balls without disturbing the headcover. Then hit 20 balls with the Step-Through drill. Continue checking the grip before every session.
Week 3: Integration. Hit full shots on the range combining the grip, face, and path changes. Use alignment sticks for setup. Goal: hit 50 percent of drives with a straight or slight draw ball flight.
Week 4: Course transfer. Play 9 or 18 holes focused on the new swing. Do not revert to old habits when the pressure is on — trust the changes. Use your pre-shot routine to reinforce the new pattern before every swing. If the slice creeps back, it is almost always the grip loosening — check it first.
You can also complement this technical work with smart course management that minimizes the damage while you are making the transition. Playing to the wide side of fairways and choosing clubs that reduce slice spin (hybrids instead of long irons, for example) will protect your scores while your swing changes take hold.
Fixing a slice is not mysterious. It requires understanding the face-path relationship, making specific grip and swing changes, and committing to deliberate practice over four weeks. The drills in this guide work — but only if you do them consistently. Put in the time, and the slice will become a distant memory.
