The slice is the most common miss in golf, and it has ruined more rounds, shattered more confidence, and sold more magic training aids than any other swing fault. If your drives curve sharply from left to right (for a right-handed golfer), you know exactly how frustrating it is to watch your ball sail into the trees, the rough, or the next fairway over — despite feeling like you made a reasonable swing. The good news is that a slice is not a life sentence. Once you understand what causes it, fixing it becomes a matter of targeted practice rather than guesswork.
In this guide, we will break down the mechanics of why your ball slices, walk through the most effective drills and swing fixes, and give you a practice plan that can straighten out your ball flight within weeks. If you are also struggling with contact issues alongside your slice, our guides to hitting irons consistently and stopping thin shots address those related fundamentals.
What Causes a Slice
A slice occurs when the clubface is open relative to the club’s path at impact. That is the complete explanation in one sentence, but understanding the nuances of this relationship is crucial for fixing the problem. Your ball’s initial direction is primarily determined by where the clubface is pointing at impact, while the curve of the ball is determined by the difference between the face angle and the swing path.
For a typical slicer, the swing path moves from outside to inside (across the ball from right to left for a right-handed golfer), while the clubface is open to that path. This combination produces the left-to-right spin that curves the ball into trouble. The bigger the difference between path and face, the more severe the slice. Some golfers have a relatively neutral path but a wide-open clubface, while others have a severely out-to-in path with a face that is only slightly open — both produce a slice, but they require different fixes.
The Grip: Your First Line of Defense
Before changing anything in your swing, check your grip. A weak grip — where your hands are rotated too far to the left on the handle (for a right-handed golfer) — makes it physically difficult to square the clubface at impact. When you look down at your grip, you should be able to see two to three knuckles on your left hand. If you can only see one knuckle, your grip is too weak and is likely a major contributor to your open clubface.
Strengthening your grip means rotating both hands slightly to the right on the handle. Your left thumb should sit just to the right of center on the grip, and the V formed by your left thumb and index finger should point toward your right shoulder. Your right hand mirrors this position, with the V pointing to your right shoulder as well. This adjustment alone can close the clubface several degrees at impact, significantly reducing or even eliminating a slice for many golfers. Give yourself at least a week of practice with a stronger grip before deciding if additional changes are needed — it will feel uncomfortable at first, but that discomfort is the feeling of change.
Fixing Your Swing Path
If your grip is solid but you still slice, the next place to look is your swing path. An out-to-in swing path is often caused by starting the downswing with the shoulders rather than the lower body. When your shoulders fire first, they pull the club across the ball from outside the target line, creating the left-to-right spin that defines a slice.
The fix is to initiate your downswing with a slight lateral shift of your hips toward the target, followed by hip rotation. This sequence drops the club into a shallower, more inside path. Think of it as creating space for the club to swing from inside to outside rather than cutting across the ball. A helpful mental image is swinging toward right field in baseball rather than pulling across your body.
Your setup can also influence your swing path. If your shoulders are aimed left of the target at address — which many slicers do unconsciously as they try to compensate for the curve — your swing will naturally follow your shoulder line and move out-to-in. Check your alignment regularly by placing a club on the ground parallel to your target line during practice. Your feet, hips, and shoulders should all be parallel to this line or even slightly closed (aimed slightly right of the target).
Five Drills to Fix Your Slice
The Headcover Drill
Place a headcover or small towel just outside your ball, about two inches toward you. If your swing path is out-to-in, you will hit the headcover on your downswing. The goal is to swing through the ball without touching the headcover, which forces you to approach from inside the target line. Start with half swings and gradually increase to full swings as the inside path becomes more natural. This drill provides immediate physical feedback and is one of the most effective slice-fixing tools available.
The Split-Grip Drill
Grip the club normally with your left hand, but slide your right hand down the grip so there is a two-inch gap between your hands. Make slow, controlled swings with this split grip. The separation between your hands makes it much easier to feel the clubface rotating through impact. If you tend to hold the face open, the split grip exaggerates the sensation of closing it. Hit twenty to thirty balls this way before returning to your normal grip, and you will likely find that the face release feels much more natural.
The Feet-Together Drill
Address the ball with your feet touching. This stance makes it nearly impossible to sway or lunge at the ball with your upper body, which are common causes of an over-the-top move. With your feet together, you are forced to rotate rather than slide, which naturally promotes a more inside swing path. Start with a pitching wedge and half swings, focusing on balance and rotation. Gradually increase club length and swing speed as your balance improves.
The Glove Under the Arm Drill
Tuck a glove or small towel under your right armpit (for right-handed golfers) and keep it there throughout your swing. This drill maintains the connection between your right arm and your body during the downswing, preventing the arm from casting outward and creating an out-to-in path. If the glove falls out before impact, your right arm is separating from your body too early. This simple constraint can dramatically improve your swing path within a single practice session.
The Exaggerated Draw Drill
Set up with your body aligned well to the right of the target — about 30 degrees right. Aim the clubface at the target, but swing along your body line. This setup forces you to swing dramatically from inside to outside, producing a right-to-left draw. The shots will likely start right and curve left. The point is not to play golf this way, but to feel what an inside-out path actually feels like in your body. After hitting twenty to thirty balls with this exaggerated setup, gradually reduce the alignment offset until you are square to the target. The inside-out feeling should carry over.
Common Mistakes When Fixing a Slice
The most common mistake golfers make when trying to fix a slice is aiming further left to compensate for the curve. This actually makes the problem worse because your body follows your aim, producing an even more out-to-in path and more slice spin. Aim where you want the ball to go, not where you expect it to end up based on your current ball flight.
Another mistake is trying to fix the slice by rolling your hands over aggressively through impact. While the clubface does need to close, forcing a hand flip creates inconsistency and often produces the opposite miss — a snap hook. The rotation should come from your body turning through the shot with your arms staying connected, not from an independent hand manipulation. Building golf confidence alongside these mechanical fixes is also important, because tension from fear of the slice makes the swing even tighter and more out-to-in.
A Practice Plan to Fix Your Slice
Commit to the following plan for three weeks and you should see significant improvement. During the first week, focus exclusively on your grip. Practice your new, stronger grip at home for a few minutes each day, and hit balls at the range with nothing but grip awareness. During the second week, add the headcover drill and the feet-together drill to every practice session. Hit at least fifty balls with each drill before moving to free swings. During the third week, focus on the exaggerated draw drill and the glove-under-the-arm drill, gradually reducing the exaggeration as your new path becomes natural.
Throughout all three weeks, record your swing on video regularly. The out-to-in path and open face are easy to see from a down-the-line camera angle. Compare your videos week to week to track progress. If you have access to a launch monitor, track your club path and face angle numbers — you want your path number to move from negative (out-to-in) toward zero or slightly positive (in-to-out), and your face-to-path relationship to narrow. Our guide to how launch monitors work explains the data you will see.
When to Consider a Lesson
If you have worked through the grip, path, and drill progressions above for several weeks without meaningful improvement, consider booking a lesson with a PGA professional. A good instructor can identify compensations and habits that are difficult to self-diagnose, and they can provide real-time feedback that accelerates the learning process. Look for an instructor who uses video analysis or launch monitor data, as these tools provide objective confirmation of what is changing in your swing. Even one or two targeted lessons can save you months of frustrated range sessions. If pressure or anxiety about your slice is part of the problem, our guide to handling pressure on the golf course offers mental strategies that complement these technical fixes.
The Bottom Line
Fixing a slice is not about finding one magic move — it is about understanding the relationship between your clubface and swing path, then systematically addressing whichever element is more out of alignment. Start with your grip, move to your path, and use the drills in this guide to build new motor patterns. With consistent, focused practice, the slice that has plagued your game can become a thing of the past, replaced by a controlled fade or even a draw that adds distance and accuracy to every tee shot.
