Tip of the Week: Don't Hit the Wall 11/18/02 7:29 PM By Tony Lance, TENNIS Magazine Nov. 18, 2002--Perhaps the most frustrating error tennis players make is hitting the ball into the net. Though often caused by ambitious shotmaking and strokes produced with little margin for error, the problem can also be due to the transparent nature of the net itself. Because you can see through the net to the other side of the court, you can sometimes be fooled into aiming lower than you should. To prevent this visual trickery, imagine that the net is a solid wall. (Some instructors even go so far as to drape fabric over the net to enhance the effect.) This will give you a more realistic view of the barrier in the middle of the court and help you hit your shots higher. That, in turn, will mean more consistency and greater depth.
