Question

State the role of third umpire in cricket. State the principle on which it works.​

Answer 1

Answer:

The third umpire (or TV Umpire) is an off-field umpire used in some cricket matches, particularly international matches. Their role is to make the final decision in questions referred to them by the two on-field umpires or the players. The third umpire is also there to act as an emergency on-field umpire if required.

Answer 2

They make the final decision and work on the principle of DRS.

• A third umpire is an umpire who is off field having the task to make the definitive call in cases where the two on-field umpires or the players have referred them.
• The term DRS stands for Decision Review System. It is an automated mechanism that helps the third umpire to come to a conclusion.
• Using a wireless machine, the field umpire may refer a near judgment to the third umpire about the dismissal of a batsman, catches, or boundaries. Via a  television screen, the third umpire communicates his verdict.
