Playing spin, footwork drill
In this exercise, the batsman shadow bats a backward shot and the practice partner positions a cone or marker alongside the back foot. Similarly a shadow advancing down the pitch shot is performed. This is to show the batsman the distances they can cover by moving forward or back.
The advancing distance covered mostly coincides with a good length that batsman normally defend. In this drill, anything on a good length or fuller, the batsman is to advance and either hit the ball on the full or half volley. The batsmen should reach the front cone.
Anything shorter than the front cone represents a short delivery to which the batsmen gets deep in the crease and plays a back foot shot alongside the cone.
