Out-to-In
Also known as: outside-in, over-the-top path
Out-to-in describes a clubhead cutting leftward across the target line as it meets the ball, for a right-hander. This means the over-the-top delivery underneath fades, pulls and slices.
An out-to-in club path is a swing direction where the clubhead travels from outside the target line to inside it through the impact zone. This is the most common path fault among recreational golfers and is the direct cause of the classic slice. The out-to-in path is often called "over the top" or "across the body". This is because of how it feels. This means the club crosses from the right side (for a right-hander) to the left, cutting across the intended ball flight. Despite producing ball flight that starts left and curves right, the golfer often feels like they are "swinging at the target."
The physics are unambiguous. This means the D-plane model of ball flight predicts that an out-to-in path with an open face (relative to the path) produces left-starting, right-curving flight. This means the classic slice. The same out-to-in path with a square face (pointing along the path, which is left) produces a pull that goes straight left. And an out-to-in path with a closed face (closed relative to the path, pointing more left than the path) produces a pull-hook. Most recreational slicers show the first pattern — out-to-in path combined with an open face that produces the familiar banana-ball curve.
Fix strategies for out-to-in path target the root cause. This is almost always improper sequencing in the transition (upper body firing before lower body) combined with a steep angle of attack. Drills that encourage an inside attack. This means "swing to right field" for a right-hander, "hit the inside of the ball". This means re-orient the mental model of the swing direction. Structural changes that shallow the shaft in transition (lower-body-led downswing, dropping the trail elbow) address the mechanical root cause.
To feel an in-to-out path for the first time, set up to the ball and imagine another ball placed 12 inches behind the real ball and slightly to the inside. This means swing as if you want to hit that inside ghost ball first, then the real ball. This inside-attack mental image produces the in-to-out feeling that reduces the out-to-in path.
Use two alignment sticks laid in a "gate" outside the ball (one pointing at the target from just outside the ball, one pointing at the target just inside the ball) and practice swinging through the gate without hitting either stick. This means the outside stick penalizes out-to-in path. At the same time, the inside stick prevents excessive in-to-out, teaching the correct moderate positive path.
Example
A player who pulls iron shots and slices the driver is almost certainly swinging out-to-in — the same path, the face just differs.
How it shows up on video
From a down-the-line camera angle, an out-to-in path is visible as the club shaft "looping" outside the backswing plane in the downswing. This means the clubhead moves toward the ball from outside the target line. The shaft appears to cross over or above the original downswing plane before impact. Divots point left of the target (for a right-hander). From face-on, out-to-in path often shows the lead shoulder "throwing" outward at the start of the downswing rather than staying down and in, as the upper body fires to initiate the downswing instead of the lower body.
Common mistakes
- Aiming further left to compensate for the slice — this reinforces the out-to-in path by removing any feedback pressure to change the delivery direction. The path must be fixed, not accommodated.
- Opening the stance to fix the slice — an open stance encourages even more of a left-to-right swing path. The fix is a better transition, not a more open setup.
- Swinging "harder" when slicing — more force applied to an out-to-in path produces a more severe slice because the path becomes more exaggerated. Speed without path correction makes the miss worse.
- Only working on grip to fix the slice — a stronger grip closes the face but does not fix the out-to-in path. A stronger grip with an out-to-in path produces a pull or pull-hook rather than a draw.
In SwingVantage Motion Lab
SwingVantage can estimate out-to-in path from multiple video indicators. This means divot direction visible in video, the starting direction of ball flight, and observable shoulder and shaft positions in the transition. The system identifies the trait "loop over the top" movement in the downswing from down-the-line footage and the shoulder-throw from face-on footage, with confidence labels based on available video quality.

- In-to-OutIn-to-out describes a clubhead travelling rightward across the target line as it meets the ball, for a right-hander. It is the delivery direction underneath draws, hooks and pushes.
- Over the TopOver the top means the downswing starts by throwing the club outside the backswing plane. This produces an out-to-in path that causes pulls, pull-slices, and loss of distance.
- SliceA slice bleeds away to the right for a right-handed golfer, costing both distance and fairway. It is the most common miss in the game, and it comes from a face pointing right of the head's direction of travel.
- Club PathClub path is the horizontal direction the clubhead is moving through impact, relative to the target line, in degrees. Positive is in-to-out (a draw bias); negative is out-to-in (a fade or slice bias).
