What does "DRS" stand for?


IPL 2023 Winner

DRS stands for Decision Review System in cricket. It is a technology-based system used to assist on-field umpires in making accurate decisions regarding dismissals and contentious plays. DRS aims to minimize umpiring errors and enhance fairness in the game.

How Does DRS Work?

  • Each team is allowed a limited number of reviews per innings (usually 2 in Test cricket and 1 in limited-overs matches).

  • A team can use DRS to challenge the on-field umpire's decision for LBW, caught behind, or other dismissals.

  • If the review is successful, the team retains their review. If unsuccessful, they lose one review.

Technologies Used in DRS:

  1. Hawk-Eye: Tracks the ball's trajectory for LBW decisions — shows pitching, impact, and if the ball would hit the stumps.

  2. UltraEdge/Snickometer: Detects sound to check for edges in caught-behind decisions.

  3. Ball-Tracking: Analyzes the path of the ball from release to potential impact on the stumps.

  4. Hotspot: An infrared imaging system that shows any contact between bat and ball.

  5. Slow-Motion Replays: Used for boundary checks, run-outs, and close catches.

DRS Review Process:

  1. The fielding team or the batsman signals for a review within 15 seconds of the umpire's decision.

  2. The on-field umpire refers the decision to the third umpire for analysis.

  3. The third umpire uses various technologies and camera angles to reach a conclusion.

  4. The final decision is communicated back to the on-field umpire, who signals it to the players and spectators.

DRS Call Terms:

  • Umpire's Call: If the ball is marginally clipping the stumps, the on-field umpire's original decision stands.

  • Out: The batsman is dismissed.

  • Not Out: The batsman survives.

Significance of DRS:

  • Reduces Umpiring Errors: Corrects clear mistakes, ensuring fairness.

  • Strategic Element: Teams use DRS strategically to avoid losing valuable reviews.

  • Controversies: Despite its accuracy, disagreements arise due to Umpire's Call and interpretation of technology.

DRS has become a crucial part of modern cricket, balancing technology with on-field judgment to maintain the integrity of the game.
