as a beginner i have taken some instruction by local pros on my swing basics but i am still having problems topping the ball on almost all my shots.

is there a drill or something i can do other than driving a stake in the ground and tieing my head to it. i seem to be in the right place in my practice swing but usually come up to top most shots. getting a nice straight 100 yd shot along the ground with my driver....lol.

can someone suggest a drill or something to work on staying down on the ball?

thanks

john
