How to check if the bowler is throwing instead of bowling in cricket? Is there any technology for checking throw bowling in cricket?
If we say the bowler is literally throwing the ball for example like this:
then the umpire shall declare it as a No-ball imminently.
If we say the bowler bowls throw balls in bowling action. That means he is running and performing the same action as bowling like this:
but not bowling properly (i.e. still throwing the ball), then if umpires catch such action during the match (that is totally up to them) they can call it a no-ball immediately. However, even if they don't catch such illegal bowling actions, the report for the illegal bowling actions is generated by match officials. If any illegal action found they submit the report the the relevant team manager. And process further. You can check the full procedure on Illegal Bowling Actions PDF.
A bowler will be wired up with number of sensors, and Biomechanics experts - Human Movement Specialists monitor the action.
