Hi Utkarsh,

It is important to watch the ball really carefully.  By watching the ball you will get the earliest information as to where the ball is going.

The next important thing is to be stable when you hit the ball.  I often see players still moving when attempting the backhand topspin third ball.  Wen you are stable your shot will improve quickly.
