Waldner ball toss

Hi Alois.

At 34:17    https://www.youtube.com/watch?v=qoxVZw2ZwNI    Waldner throwing the ball in a special way. 

Spin on the ball at throwing in service???....Please explain me about this technique.

I have no doubt that you know about this technique.You are an excellent player.

Hi,

This is his normal ball toss.  They have just shown it from a high camera.  You can see from there that he hides the ball which was legal in those days.

Always nice to watch a bit of Waldner.
