"Place a Katchett board in front of you and get the thrower to throw the ball at a good pace, so it tests your reaction.
See how many balls out of six you can catch. If you really want to test yourself, put something like a stump in the way to try and distract you. This will make you watch the ball even harder and test your concentration. Try to get your head and eyes in line with the ball so you can watch the ball right into your hands.
This drill is an excellent way to develop your slip catching technique."
