Focus on release area
It is very helpful for a batsman to quickly determine the line and length of the delivery. In preparation for this, it is hard to watch the ball in the bowlers hand as it is winding in the action. It is also hard to pick up the ball early if the focus is too general. A moment before the bowler lets go of the ball, the batsman should focus on an area where the ball is likely to be released from. This will help the batsman to pick up or see the ball earlier.
