Each morning, thus, there is a session on the Astroturf laid out inside the indoor academy; each session has a specific objective.

On the day in question, the focus is on getting a good stride in to your shot. Chappell tells his wards how it is done: As the ball is delivered, you pick the length, and that in turn informs your decision about whether to play off the front foot, or the back.

Right now the focus is on driving on the off - so the length is going to be good. Your first act is to get your weight onto the back leg, that is, to "load" the back leg. The front foot is then free to glide forward towards the pitch of the ball. Simultaneously, the wrist and back arm "loads" on the backswing; the bat then arcs smoothly forward to the point of impact.

Throughout the session, as the kids work on their driving and their pulling, Chappell and Frazer repeat certain basic mantras: Get the full stride in. Do not throw your bat at the ball. Hit through the line, not at the ball. Don't bother powering it, time it right.

Noticeably, neither the two imported coaches, nor the five domestic ones supervising the session, attempt to change each kid's style too much - no lecturing, for instance, on the ideal back lift, on the wrist-cock, or even on getting the head over the ball at the point of impact.

Information overload is even more important than lack of information, Chappell explains. These are early days; for now, let the boys get the confidence that comes from just hitting the ball, and getting it to go off the middle. Get the kids hitting with confidence and a measure of skill, first - any fine-tuning that is required is a secondary step, that can follow when they are mentally in a place where they can absorb the finer points.
