Serving grip back to rally

How do you hold the bat while serving and how do you automatically change the position your hand is in  as soon as you finish serving or do you have to change it? 

Hi Muhammad,

The grip for the Pendulum serve is reasonably simple.  You just take the 3 fingers away from the handle and put them behind the handle.  So after you have served you can easily just place those 3 fingers back around the handle.
