How to see through fake movements

Yesterday, I encountered a person who served a ball with a lot of fake movements. How do you see through their fake movements? 

Thanks!

Hi Ken,

The important things to focus on are the contact of the bat on the ball and the flight of the ball.

It is easy to be distracted by the extra movement of the fake actions.  So watch the contact carefully.  Remember they can only hit the ball once and with one type of spin.

Then the flight of the ball will give you some more information on the spin and speed of the serve.
