To play a one-handed backhand shot, place the palm of your hand on top of the handle then move the racquet inwards a quarter turn.

The thumb should fall diagonally across the back of the grip, though some players wrap it all the way round.

The direction does not matter but it is important the inside of the thumb is touching the flat part of the handle.

An easy way to find this grip is to put the racquet under your left arm with the handle sticking out forwards.

Grab hold of the grip and pull the racquet out. You should then have the correct grip for a one-handed topspin backhand.
