This will cause the ball to start to the left of the target. This puts the slice spin on the ball and forces it to curve back to the right. It's a weak shot that's hard to control and doesn't go very far. To correct the slice, stay on your swing plane by taking the club away from the ball slightly on the inside. Then, initiate your downswing by shifting your weight to the left side.
Most slicers stay on their right sides too long, causing their bodies to twist.
This causes them to pull the ball to the left of the target, as I mentioned above. The toe of the club should pass the heel at impact.
