As a batsman in cricket it is essential that you have a good batting grip to enable you to play the full range of batting shots with full control and precision.
The way a batsmen grips the bat often varies slightly from player to player which is some times reflected in their batting style. For simplicities sake the easiest way to hold a bat correctly is to lie your bat face down on the ground and pick it up with both hands as though it were a small axe and you shouldn’t go to far wrong.
However, there is a definite recognised and 'correct' bat grip which is taught by the English Cricket Board (ECB).
After picking up the bat ensure you have your fingers and thumb wrapped around the center of the handle with your hands close together.
The shape should form a 'V', in line between the splice and the edge.
This means that when you are holding the bat a 'V', as such is formed between where the inside of the thumb and fore finger hold the bat with each hand. The two 'V's on each hand should line up almost centrally between the splice/handle and the leading edge.
This is quite hard to explain without out a diagram, but if you have a cricket bat nearby you should be able to try this out.
Often some players rest their fore-finger down the side of the bat/handle and not closed around the grip.
