|A guide to what chucking's all about|
|Around the Academy:
Confused about chucking? Worried an umpire's going to call you up for a dodgy action?
The Sport Academy explains what this chucking business is about - and gives you a guide to a good old fashioned legal ball.
The best way to destroy a cricketer is tell to them they are a cheat or a 'chucker'.
But what exactly is chucking and how do we avoid it?
The above graphic is an illustration of a legal ball - the bowlers arm remains straight.
Putting it simply, a throw (according to the rules of the game) is one that comes from the elbow.
Darts players, javelin throwers, shot-putters - they all bend the arm to get maximum leverage from it.
Bowlers must not or the umpire will call no-ball.
Muttiah Muralitharan, who has been put under scrutiny on many occasions, has a good excuse.
He has a slight deformity of his elbow, he is unable to straighten his arm.
You are allowed to have your arm bent, so long as it then does not straighten.
So although it may look like he is bending his limb when bowling, officials have decided, he is not.
This means his action is within the rules.
Other players such as Brett Lee, Shoaib Akhtar and James Kirtley have also had the finger pointed at them for 'chucking'.
But the secret of avoiding controversy is to keep that bowling arm straight.
