I have heard various theories. But one that i remember is Tendulkar despite lack of genuine quick bowlers in India, uses this 15 yard technique where he would bat 15 yard from bowler as against 22 yards. He would practice with wet Tennis ball to practice that. I am not even sure if these guys adopt any kind of practice to negotiate short stuffs. Even if you don't score you should be able to leave it comfortably.
Another technique is having a throw down from someone in different areas and different heights to improve the reflex. It is generally a responsibility of coach. Kirsten has to step in big time here.
This is getting beyond joke now.
I mean what is Kirsten doing as coach.
