A wicketkeeper and a batsman have few similarities like stance and balance. It needs to be correct in order to judge gather the ball quickly and can stump out the batsman. For that, he needs to do a lot of hard work. The more he practices, the better he will become. If a keeper is technically correct, then he does not need to dive much. But, if his technique is not good, then he would have to dive a lot. Because he is facing difficulties in judging the ball and due to which he would not be able to gather it correctly. But, if he dives a lot, then it might save him.
If a keeper faces a back issue or pain in the neck, then it indicates that he is not using the right technique. He needs to work on his technique if he wants to correct it. So, he does not face any issues. In case if he is finding it difficult to move, then he needs to work on his stance.
The most underrated partnership is between the wicketkeeper and the bowler. On many occasions, both the keeper and the bowler make plans for the batsman. And they some times bowl outside the off-stump or outside the leg stump. So that they can create mistakes from the batsman so that they can dismiss him.
Sometimes, a bowler bowls a bad delivery down the leg side. But, the keeper needs to try and make sure that he saves the ball from going to the boundary through his dive. It will give a boost to the bowler if he saves the boundary.
The trust factor is the most important thing in this partnership. If a bowler won’t discuss the plans with the keeper, then it might be possible that even the keeper misses the stumping chance or catch. A wicketkeeper needs to have an understanding about which bowler will bowl which delivery. And what variations he has and when he is going to use it.
