A straight ball on a good length has to be treated with respect.
The principle of a forward defensive stroke is to block the ball rather than to score runs.
Every batsman needs a solid defence to build big scores.
The head and front shoulder should lean into the line of the ball with the front leg taking a stride towards the pitch of the ball, bending to take the weight.
The back leg remains straight.
The bat should swing down and make contact with the ball beneath the eyes, with the face of the bat angled towards the ground.
The bat should be slightly forward of the front leg and close to the pad.
Raise the heel of your back foot and hold your finishing position rather than following through.
