Question

Write about the role of the third umpire in
Cricket. State the principle on which it works.

Answer 1

Answer:  

The third umpire is none other than the TV umpire. His duties include:  

• Checking replays and different camera angles to determine if the batsman has made his ground in close run-out decisions that the on-field umpires cannot determine with their naked eye in real-time.

• The same procedure is followed for stumping decisions.

• When a batsman is dismissed, the third umpire checks if the delivery is legal or a no-ball due to overstepping.

• To check a catch is cleanly taken when catches are taken inches off the ground.

• To check if the fielder has touched the boundary line when he slides/catches the ball centimeters away from it.

The decision of the third umpire is either relayed over the big-screen or is communicated via a walkie-talkie to the on-field umpires

• They make the final decision and work on the principle of DRS.  The term DRS stands for Decision Review System. It is an automated mechanism that helps the third umpire to come to a conclusion.
