Explanation:

The Umpire Decision Review System (UDRS) is a technology-based system used in cricket to review and overturn on-field umpire decisions. Captains can request a limited number of reviews per innings to challenge on-field decisions for dismissals or specific incidents like LBW appeals, caught-behind, and contentious catches.

The UDRS employs various technologies to aid in making accurate decisions during reviews. Ball-tracking technology predicts the path of the ball and its impact on the stumps, helping determine LBW decisions and verifying other factors. Ultra-edge technology assists in detecting whether the ball touched the bat or pad, particularly in caught-behind reviews. Hotspot uses thermal imaging to identify ball-to-bat contact, further aiding in analyzing edges and contentious catches.

The DRS protocol outlines the process of conducting reviews, including the timeframe for challenging decisions, communication between on-field and third umpires, and the third umpire’s role in making decisions.

Teams must use the UDRS challenges judiciously, as an unsuccessful review costs the team one of their allotted challenges, while a successful one allows them to retain the review.

The introduction of the UDRS has significantly reduced umpiring errors and contributed to fairer decisions in cricket. By incorporating technology, the system enhances the overall integrity of the game and instills greater confidence in players and spectators regarding the accuracy of decisions.

Cricket authorities are committed to continuous improvement in the UDRS, regularly refining and updating the system to maximize accuracy and address any potential shortcomings, ensuring that the UDRS remains an indispensable tool in modern cricket for fair and precise decision-making.

DRS ball impact rules

DRS Ball Impact Rules

Aspect Rule Explanation
Impact within Stump Line If the ball impacts the stumps and at least half of the ball is in line with the outer edge of the stumps, the decision will be “Umpire’s Call” – meaning the on-field umpire’s decision stands. If more than half of the ball is in line with the outer edge, it will be considered as hitting the stumps.
Impact Outside Stump Line If the ball impacts outside the line of the stumps, the batsman is considered not out, regardless of the on-field umpire’s decision.
No Shot Offered If the batsman offers no shot, and the ball impacts the stumps, the decision will be “Umpire’s Call.” The ball must still hit at least half of the ball in line with the outer edge of the stumps to be considered hitting the stumps.
Inside Edge If the batsman edges the ball onto the pads, the ball-tracking technology considers the point of impact with the pad and the projected path of the ball to determine if the ball would have hit the stumps.
Ball-Tracker Margin of Error The ball-tracking technology has a margin of error associated with it. The decision will be “Umpire’s Call” if the projected path of the ball and the stumps overlap within this margin. If they don’t overlap, the original decision stands.
Impact on Bails If the ball impacts the bails directly without hitting the stumps, the decision is not out, even if the ball-tracking technology shows the ball would have hit the stumps.

Explanation:

The Decision Review System (DRS) has revolutionized decision-making in cricket, especially for LBW (Leg Before Wicket) decisions. The DRS ball impact rules govern how the technology interprets the ball’s trajectory and its impact on the stumps to determine the batsman’s fate.

When reviewing an LBW appeal, if the ball impacts the stumps and at least half of the ball is in line with the outer edge of the stumps, the decision will be “Umpire’s Call.” In this case, the on-field umpire’s original decision stands. If more than half of the ball is in line with the outer edge, it will be considered as hitting the stumps, and the batsman will be given out.

If the ball impacts outside the line of the stumps, regardless of the on-field umpire’s decision, the batsman will be considered not out.

When the batsman offers no shot and the ball impacts the stumps, the DRS technology considers if at least half of the ball would have hit the stumps to give the decision as “Umpire’s Call.”

If the batsman edges the ball onto the pads, the point of impact with the pad and the projected path of the ball is taken into account to determine if the ball would have hit the stumps.

It’s important to note that the ball-tracking technology has a margin of error associated with it. If the projected path of the ball and the stumps overlap within this margin, the decision will be “Umpire’s Call.” If they don’t overlap, the original decision stands.

Furthermore, if the ball impacts the bails directly without hitting the stumps, the decision is not out, even if the ball-tracking technology shows the ball would have hit the stumps.

The DRS ball impact rules aim to ensure fair and accurate decisions, while also acknowledging the limitations and margin of error associated with technology. These rules have become an integral part of modern cricket, enhancing the game’s integrity and providing players with a recourse to challenge on-field decisions in critical moments.

Decision review system (DRS)

Decision Review System (DRS)

Aspect Description
Purpose The Decision Review System (DRS) is a technology-based system used in cricket to review on-field umpire decisions. Its primary purpose is to rectify potential errors and improve decision accuracy. Teams can challenge on-field decisions, and the third umpire uses technology, such as ball-tracking and UltraEdge, to review the decision and provide a conclusive outcome. The DRS aims to ensure fairness and enhance the integrity of the game.
Ball-Tracking Ball-tracking is a crucial component of the DRS. It uses technology to predict the path of the ball after pitching and helps in assessing LBW decisions. The system tracks the ball’s trajectory and provides data on whether the ball would have hit the stumps or not. Ball-tracking assists in making accurate decisions on the leg before wicket appeals.
UltraEdge UltraEdge, also known as Real-Time Snicko, is another essential aspect of the DRS. It utilizes sound sensors and microphones to detect any faint edges or contact between the ball and the bat. UltraEdge provides conclusive evidence on whether there was a bat involved in an LBW or caught-behind decision, assisting the third umpire in making accurate decisions.
Hawkeye Hawkeye technology is used in the DRS to analyze the ball’s trajectory, especially for LBW reviews. It provides a visual representation of the ball’s path and indicates where it would have hit the stumps. Hawkeye aids the third umpire in making decisions on whether the ball was hitting the stumps or missing them, contributing to accurate LBW decisions.
Limited Reviews Each team is allowed a limited number of reviews per inning in the DRS. If a team’s review is successful (the on-field decision is overturned), they retain the review, but if the review is unsuccessful, they lose it. This system encourages teams to use their reviews judiciously and only challenge decisions they genuinely believe to be incorrect.
