How to Fix Your Slice: The A-Swing Method Explained
Oli Tucker
PGA Golf Coach
The slice is the number one problem in amateur golf. That weak, left-to-right ball flight that robs you of distance and puts you in trouble off the tee. I've helped hundreds of golfers fix theirs -and one of the most effective methods I use is based on the A-Swing concept.
Why You Slice the Ball
A slice happens when the clubface is open relative to the path of the swing at impact. Most slicers have an out-to-in swing path (over the top) combined with an open face. The result? A glancing blow that puts side spin on the ball, sending it curving right. The harder you swing, the worse it gets.
What Is the A-Swing?
The A-Swing, popularised by David Leadbetter, is a method that changes the backswing motion to naturally produce a better downswing path. Instead of taking the club back on a wide, outside path (which leads to over-the-top), the A-Swing uses a more inward, compact backswing. This sets up an inside-out downswing path -the exact opposite of what causes a slice.
How I Teach It with TrackMan Data
At Tempo in Kilburn, I use TrackMan launch monitor technology to show golfers exactly what their club path and face angle are doing at impact. You can't fix what you can't measure. We'll typically see a slicer come in with a path of -5 to -8 degrees (out-to-in) and a face 3-4 degrees open. The A-Swing adjustments usually shift the path to +2 or +3 degrees within the first session -and that's where the magic happens. Instead of a slice, you start seeing a draw.
3 Key Moves to Start With
First, narrow your takeaway -feel like the club moves inside and slightly upward, not wide and outside. Second, let your lead wrist hinge earlier in the backswing, creating a more vertical wrist set. Third, start the downswing by bumping the lead hip toward the target before the arms move. This sequence naturally drops the club onto an inside path. I demonstrate all three in the video below.
