With the Cricket World Cup starting on 14 February 2015 in
Australia and New Zealand, there are numerous bowlers who have been
selected by their countries to represent them, who will be under
the watchful eye of the umpires for the legality of their bowling
actions.
According to the laws of cricket, the definition of a 'fair
delivery in respect of the arm' is that the ball must not be
thrown. Furthermore the ball is fairly delivered in respect of the
arm if, once the bowlers arm has reached the level of the shoulder
in the delivery swing, the elbow joint shall not straighten
partially or completely from that point until the ball has left the
hand.
The International Cricket Council (ICC) Regulations state that
an acceptable level of elbow extension has been set at a maximum of
15 degrees for all bowlers and types of deliveries. This refers to
the extension of the forearm relative to the upper arm to the
straight position.
