What are the fielding and wicketkeeping rules?

Stage 2 Match Day Rules 6.7:

• Two wicketkeepers: each team uses 2 keepers, each for half of the allocated overs of the innings.
• Close fielders: no fielder within 10 metres of the striker, except the wicketkeeper, slips and gullies.
• Front of the bat: no fielder may stand within 2 metres of the playing surface in front of the striker's wicket.
• Leg side: more than two fielders behind square leg is a no ball.
• Rotation: coaches are encouraged to rotate fielding positions so players experience them all.
• Extra players: with more than 9 players present, the extras rotate on and off the field each over.

A breach of any fielding restriction is a no ball.
