Either just before or at contact with the ball let us the head will begin to move in anticipation of watching the ball as it leaves the racket. This means that the eyes will lose focus and it becomes impossible to see the contact.
The more we practice “Watching the Ball” the worse the contact with the ball becomes.
Players who have a great volley tend to be “Natural Volleyers” who have never been coached and found a natural way of seeing the contact.
To get great timing on your volley the try “Watch the Ball, Watch the Racket”
As the ball approaches tell yourself your going to see the ball and then as soon as you hit it you are going to see the racket. This strange piece of advice has amazing results.
Your head will have to be static to follow this instruction and so you will see the contact with the ball. The racket need only be seen for a fraction of a second and then as you look up, you see the ball flying into the court. It is usually about 2 meters away when you see it.
This is very simple but very unnatural and requires intense concentration at first. But as the contact with the volley becomes better and therefore the power and control become better the tendency to “Watch the Ball-Watch the Racket” Becomes natural.
