The third umpire is an off-field official in cricket responsible for making decisions with the help of technology when on-field umpires need assistance. The third umpire watches the game on monitors, using various tools to review decisions and ensure accuracy.


Responsibilities of the Third Umpire:

  1. Run-Out and Stumping Decisions: Verifying whether the batsman is out or not when there's doubt.

  2. Caught Behind and Edges: Using technologies like UltraEdge or Snickometer to check for thin edges.

  3. Boundary Checks: Confirming if a fielder's foot touched the boundary while stopping the ball.

  4. Clean Catches: Deciding if the ball was fairly caught before touching the ground.

  5. No-Balls: Reviewing front-foot no-balls when required. In some series, all deliveries are checked by the third umpire.

  6. Review System (DRS): Assessing appeals for LBW, caught behind, or other dismissals through the Decision Review System (DRS).

  7. Player Conduct: Assisting in disciplinary decisions like on-field misconduct or code-of-conduct breaches.


Technology Used by the Third Umpire:

  • Hawk-Eye: Tracks ball trajectory for LBW decisions.

  • UltraEdge/Snickometer: Detects faint edges or contacts.

  • Ball-Tracking: Assesses impact, pitching, and hitting the stumps for LBW.

  • Slow-Motion Replays: To review close calls and verify dismissals.

  • Zoom and Split Screens: For boundary and stumping checks.


Process of a Third Umpire Decision:

  • On-field umpires signal a review by forming a T-shape with their arms.

  • The third umpire reviews multiple camera angles and technologies to reach a decision.

  • The decision is communicated back to the on-field umpires, who relay it to the players.


Impact of the Third Umpire:

  • Reduces human errors, ensuring fair and accurate decisions.

  • Maintains the spirit of the game while embracing technological advancements.

  • Adds suspense and excitement to crucial moments in the match.

The third umpire has become a vital part of modern cricket, blending technology and human judgment to uphold fairness.
