Time for some Tee?

The position of your head during the swing should not be overlooked. If you raise your head as you swing back, you likely will raise your shoulders too, and that will put your swing out of whack. And if you raise your head as you swing down and through, you'll likely top the ball.

Here's how you can test to make sure your head stays on track. Place a tee (longest one possible) in your mouth just before you address your ball on the practice range. Take your stance with the pointed end of the tee pointing directly at the ball (or,rather, the target line). Swing back, then stop at the top of your backswing.

The tee should still be pointing at the target line. Now swing down and through, but stop your swing just before your wrists break. If the tee is still pointing at the target line, your head rotation is excellent. If not, then try moving your head back and forth-no club is necessary for this exercise-while keeping the tee pointing at the target line. This is the head position you want when you make your swing.
