Divide the main group into smaller groups of 4 and set up as shown. The ball is thrown to the wicket keepers (person in the middle) right or left for them to dive onto the mats. The two players behind the mats are back-up fielders.
Stance: Slightly crouched and weight to the off side of the batter.
Weight: On the balls of feet and slightly forward.
Head and body should be behind the ball when making the catch.
Ensure the keeper's outside foot opens slightly when wanting to push off in a particular direction. This allows their hips to open, and makes the sideways movement easier.
