Why do I slice the golf ball and how do I fix it?
Physics first: what your ball is telling you
The ball flight laws measured by TrackMan are clear: the starting direction is governed (mostly) by the clubface, and the curve is created by the gap between face and path. A right-hander's slice = face open to the path, almost always with an out-to-in path.
Translation without launch-monitor numbers: if your ball starts reasonably straight and then sails off to the right, your face is open to the path the club is traveling on. You do not need more data to start fixing it.
The root cause almost nobody looks at
Most amateurs do not come over the top on purpose: the error is born in the first three feet of the swing. A takeaway dragged too far inside (clubhead behind the hands too early) leaves the club stuck, and the body compensates by coming down over the top → out-to-in → slice. It is the classic causal chain Hogan and Leadbetter describe in their fundamentals.
The fix: one thing only
Do not try to fix the face, the path and the grip all at once. One concept:
- One-piece takeaway: for the first 16 inches, club-hands-arms-shoulders move as a single unit, keeping the triangle of the arms intact.
The drill (5 minutes per session)
- Stick a tee in the ground 16 inches behind your ball, on the target line.
- As you start the swing, the clubhead must pass over the tee before it swings up.
- 10 slow reps without a ball, 5 with a ball at 70% effort.
With Birdia you can film your swing with your phone and see the 4 phases (takeaway → backswing → downswing → finish) measured on your own device, no sensors needed.

Frequently asked questions
Can I fix a slice by strengthening my grip?
A stronger grip can mask the symptom, but if the cause is an inside takeaway, the miss comes back under pressure. Fix the sequence first; only touch the grip if a professional confirms it.
How long does it take to get rid of a slice?
With a single change (one-piece takeaway) and 3 practice sessions of 15 minutes per week, most players see a smaller curve within 2-4 weeks. The key is not stacking fixes on top of each other.
Can an app help fix a slice?
It helps with what a mirror cannot do: measure. Birdia detects your swing phases and your tempo with your phone camera, and its coach only recommends drills from a cited knowledge base — it never makes doctrine up.
