High Tossing the ball while serving

I saw a lot of players tossing the ball so high while serving

What is the importance and purpose of it?

Thanks coach :)

Hi Raiane,

The high toss adds speed to the ball when it contacts the bat.  This helps you to generate more spin on the ball because it is hitting the bat at a greater speed and thereby you can make the ball spin around faster.

To some extent, the high toss can also distract the receiver from watching the contact which is an important part of receiving a spin serve.
