The Power Shot is an aggresive attacking shot played on the front foot. The aim is to hit the ball powerfully back over the bowler's head.
In the video below watch how England batter, Eoin Morgan, remains balanced, quite still and watches the the ball onto the bat. He doesn't try to smash it (it is not a slog) but keeps full control for maximum power and hits right through.
He aims to hit the ball straight so that it goes back over the bowler's head.
