Ball Flight Description
The ball starts to the right of the target line with no additional curve to the right. The divot matches the ball's direction.
Straight Right - Quick TipsGrip: Not normally a factor.
Set-up: Watch out for aiming too far to the right, or having your shoulders pointing to far to the right.
Ball Position: The ball might be too far back in your stance. This causes you to make contact when the club is still swinging to right field.
Backswing: You might be too far inside on the backswing, pulling the club away from the target line. The club should track a gentle arc on the way back, not a rapid arc to the inside of the target line.
Downswing: The club might be swinging too much to right field at impact. Your right shoulder could be dropping too soon and/or your hips might be sliding to the target, preventing the club from swinging back around to the left. Make sure your head doesn't move to the right in the downswing.
