A slice—the ball curving right for right-handed golfers—results from specific swing flaws that combine to create side spin. Understanding these causes helps you identify the problem in your own swing and target your practice to fix it effectively.
What causes a slice in golf swing?
A slice is caused by an open clubface at impact combined with an outside-in swing path. This combination creates the right-to-left spin that curves the ball right. Weak grip, hip stall, and poor sequencing often contribute to these problems. The open face sends the ball right initially, then the spin curves it further right.
The most common cause is a weak grip that opens the clubface. When your hands are rotated too far left (weak grip), the clubface opens at impact, creating the slice spin. An outside-in swing path (swinging left of target) combines with the open face to maximize the slice effect.
How does weak grip cause a slice?
Weak grip causes a slice by positioning your hands so the clubface opens at impact. When your left hand is rotated too far left (showing only one knuckle at address), the clubface can't square naturally through impact. This open face creates the right-to-left spin that curves the ball right.
A weak grip feels comfortable because it prevents the club from closing, but it guarantees an open face. Many golfers use a weak grip because it feels more natural, but this creates slices that are difficult to fix with swing adjustments alone. Strengthening your grip (showing 2-3 knuckles) helps square the face.
How does outside-in swing path cause a slice?
Outside-in swing path (swinging left of target for right-handed golfers) causes a slice when combined with an open clubface. This path often results from an over-the-top move that starts the downswing with your shoulders instead of your hips. The outside-in path sends the ball left initially, then the spin from the open face curves it right.
The over-the-top move creates the outside-in path by starting the downswing incorrectly. When your shoulders start the downswing before your hips, your club swings left of target. This path, combined with an open face, creates the maximum slice effect.
How does hip stall contribute to slicing?
Hip stall contributes to slicing by forcing an over-the-top move and outside-in swing path. When your hips stop rotating during the downswing, your upper body compensates by starting the downswing with your shoulders. This creates the outside-in path that combines with an open face to create slices.
Proper hip rotation transfers weight and creates space for your arms to swing through. When your hips stall, you lose this sequencing and often create path problems. Fixing hip stall requires starting the downswing with your lower body and maintaining rotation through impact.
How does clubface angle affect slicing?
Clubface angle at impact determines the initial ball direction and spin. An open face (pointing right of target) sends the ball right and creates right-to-left spin that curves it further right. This open face, combined with an outside-in path, creates the maximum slice effect.
The clubface angle is the primary factor in slice spin. Even with a correct swing path, an open face creates slice spin. Fixing the clubface angle—through grip changes or wrist position—is essential to eliminating slices.
How can you identify the cause of your slice?
You can identify the cause of your slice by recording your swing on video and checking your grip position, swing path, hip rotation, and clubface angle at impact. Golf swing analysis can identify these issues automatically, but understanding what to look for helps you diagnose the problem yourself.
Check your grip first—if you see only one knuckle on your left hand, you have a weak grip. Check your swing path—if your club swings left of target through impact, you have an outside-in path. Check your hip rotation—if your hips stop during the downswing, you have hip stall. Each of these contributes to slicing.
