Topspin contact straight line

Master Rosario,

I have a problem with the correct topspin. I talk about more up-spin, not sidespin-loop.

I dont know how to brush the ball in the contact with the wrist - with straight line or I must to close (rounded contact)? 

Which is the both is more used by prof. players?

Thank you in advance .

Hi Il,

It is important to develop a straight topspin.  If you are getting sidespin on the ball think about turning your wrist back slightly and brushing up right at the back of the ball instead of a little on the side.  The turning of the wrist is like opening a gate.

The top players use mainly straight topspin because you can hit the ball faster.  If you add sidespin you will have to slow your stroke down to gain consistency.
