Cricket has always been a game of fine margins, where a single umpiring decision can change the course of a match. Before technology stepped in, players and fans had no choice but to accept on-field decisions, even when they seemed questionable.
The Decision Review System (DRS) in Cricket was introduced to minimize errors, ensure fair play, and bring more accuracy to umpiring calls. Over the years, it has reshaped how decisions are made, reducing human errors and adding a layer of transparency to the game.
But has DRS truly made cricket fairer? How does it work? And what impact has it had on crucial matches? Let's break it all down.
What is DRS in Cricket?
The Decision Review System (DRS) is a technology-driven process that allows players to challenge an on-field umpire's decision. It uses various tools like Hawk-Eye, UltraEdge, and Ball Tracking to determine whether the umpire's call was correct.
Initially introduced in 2008 during a Test series between India and Sri Lanka, DRS has since become a standard feature in international cricket. Today, it is widely used across Test matches, ODIs, T20s, and major tournaments like the ICC Cricket World Cup and IPL.
How DRS Works in Cricket
DRS follows a structured process that includes:
- Player Review: A player (usually the captain or batsman) can challenge an on-field decision by signaling for a review within 15 seconds of the umpire's call.
- Third Umpire Involvement: The third umpire examines the available technology to reassess the decision.
- Technology Used in DRS:
- Hawk-Eye: Tracks the ball's trajectory to determine LBW calls.
- UltraEdge/Snickometer: Detects whether the ball has touched the bat or pad.
- Ball Tracking: Predicts the path of the ball and determines if it would hit the stumps.
- HotSpot: Uses infrared imaging to check for bat-ball contact (not always used due to cost concerns).
- Final Decision: Based on the available evidence, the third umpire either overturns or upholds the on-field umpire’s decision.
Each team is allowed a limited number of unsuccessful reviews per innings, which varies by format:
- Test Cricket: 2 unsuccessful reviews per innings.
- ODIs & T20s: 1 unsuccessful review per innings.
The Impact of DRS on Umpiring Decisions
1. Reduced Umpiring Errors
Before DRS, umpires had to make split-second decisions without technological assistance. While they got most decisions right, some crucial calls were either incorrect or highly debatable.
Since the introduction of DRS, the accuracy of umpiring decisions has increased to nearly 98%, according to ICC data. This has significantly reduced errors and prevented unfair dismissals.
2. Eliminated Howlers in Cricket
One of the biggest advantages of DRS is correcting blatant umpiring mistakes, commonly known as "howlers." In the past, players often suffered due to incorrect decisions, which could impact the outcome of a game.
A famous example was Sachin Tendulkar’s controversial LBW dismissal in the 2011 World Cup, where DRS saved him from an incorrect on-field call.
3. Made Cricket More Fair & Transparent
Fans and players now have greater trust in umpiring decisions because they can see the evidence through ball tracking, UltraEdge, and replays. This transparency has increased the overall fairness of the game.
Biggest DRS Controversies in Cricket
While DRS has improved decision-making, it hasn’t been without its controversies and flaws.
1. "Umpire’s Call" Confusion
One of the most debated aspects of DRS is the Umpire’s Call rule. If the ball is predicted to hit the stumps but less than 50% of the ball is inside the impact zone, the on-field decision stands.
Many believe this rule favors the umpires too much and creates inconsistency. Critics argue that if the ball is hitting the stumps, it should be given out, regardless of margins.
2. MS Dhoni’s “Unreviewable” LBW in IPL
In IPL 2019, MS Dhoni was given out LBW, but since the DRS was not available for that match, he had no option to review. This sparked a huge debate about why DRS isn’t used in every T20 league match.
3. The Ben Stokes "Obstructing the Field" Review
During an ODI against Australia, Ben Stokes was controversially given out for obstructing the field. The decision was reviewed using DRS, but many felt that the technology didn’t provide a clear answer, sparking heated debates.

Does Every Cricket Match Use DRS?
Despite its success, DRS is not used in all cricket matches due to high costs and technical limitations. Some reasons why DRS isn't implemented in every game include:
- Expensive technology that many cricket boards can’t afford.
- Reliability issues in smaller venues with limited facilities.
- Resistance from certain teams, like India, which initially opposed DRS until 2016.
However, ICC has been working towards making DRS more accessible and standardized across all formats.
The Future of DRS in Cricket
Technology continues to evolve, and so does DRS. Future advancements may include:
- Automated Ball-Tracking: Faster and more precise predictions.
- AI-Based Umpiring: Reducing human intervention in decision-making.
- DRS for All Domestic Matches: Making the system available at all professional levels.
With cricket becoming more data-driven, it's only a matter of time before DRS becomes a universal standard in the sport.
FAQs on DRS in Cricket
1. Who introduced DRS in Cricket?
The ICC introduced DRS in 2008 during a Test series between India and Sri Lanka.
2. What is Umpire’s Call in DRS?
Umpire’s Call is when the ball is predicted to hit the stumps, but less than 50% of it is in the impact zone, meaning the on-field decision stands.
3. Why is DRS not used in every cricket match?
DRS is expensive, and not all cricket boards can afford the technology. Some venues also lack the infrastructure to support it.
4. How many reviews does a team get in cricket?
- Test Matches: 2 unsuccessful reviews per innings.
- ODIs & T20s: 1 unsuccessful review per innings.
5. Will DRS ever replace on-field umpires?
Not entirely. While technology will continue to assist umpires, human judgment will still be required for on-field decisions
Final Thoughts
DRS in Cricket has transformed umpiring decisions, reducing errors and making the game fairer. While it has faced criticism, its accuracy and reliability have made it an essential part of modern-day cricket.
With technology improving every year, we can expect DRS to become even more precise and widely adopted, ensuring cricket remains a game of skill rather than umpiring errors.
