Most international players are very strong when the ball is pitched on or around leg stump.
If you can play this shot well, you'll definitely pick up runs square and behind the wicket on the leg side.
The timing and control of the shot comes from the wrists. A little flick at the moment of impact will close the face of the bat, helping the ball to the boundary.
You'll need good balance when playing the shot, with your head over the ball. It's a great shot to play against opening bowlers because it relies on the ball coming onto the bat.
Move both feet back towards the stumps, opening your body out towards the ball, but make sure that you keep your leg stump covered.
Keep your head forward and in line with the ball.
Bring the bat through in as straight a line as possible turning the bat face slightly towards the leg side.
You make contact with the ball in front of the body.
Control the shot with the top hand, glancing the ball away.
