What Causes a Slice at Impact?
The slice is one of the most common shots in golf. For a right-handed golfer, it curves to the right; for a left-handed golfer, it curves to the left. While there can be many swing reasons that lead to a slice, the impact condition is simple:
A slice is caused by a clubface that is open to the swing path at impact.
Face-to-Path: The Key Slice Factor
At impact, two important directions matter:
- Swing path: the direction the clubhead is traveling
- Clubface angle: the direction the clubface is pointing
When the clubface is open relative to the path, it is pointing to the right of the path for a right-handed golfer. The face is not square or perpendicular to the path. This difference between the face and the path creates the tilted spin axis that makes the ball curve into a slice.
In simple terms:
If you are slicing the golf ball, the clubface is open to the swing path at impact.
Why the Ball Curves
When the face is open to the path, the ball leaves the club with spin that causes it to curve away from the golfer. Many players describe this as side spin, though technically it is a tilted spin axis.
The bigger the difference between the clubface and swing path, the more the ball will curve.
Different Slice Patterns
Not every slice starts on the same line. The ball can start left, straight, or right depending on where the clubface points relative to the target. However, if the ball slices, the same basic rule applies:
- Pull slice: starts left and curves right
- Straight slice: starts near the target line and curves right
- Push slice: starts right and curves farther right
In each case, the clubface is still open relative to the swing path.
Key Takeaway
You do not need to overcomplicate the basic cause of a slice. The essential impact condition is:
The clubface is open to the swing path.
To reduce or eliminate a slice, work toward improving the relationship between your clubface and swing path so the face is less open at impact.
