What is the DLS Method?
The Duckworth-Lewis-Stern (DLS) method is a mathematical formula used in cricket to calculate a revised target score for the team batting second in a match affected by rain or other interruptions. It was developed by two British statisticians, Frank Duckworth and Tony Lewis, and later refined by Professor Steven Stern. The DLS method aims to ensure a fair result in a rain-affected match, taking into account the Resources available to both teams.
How Does the DLS Method Work?
The DLS method works by assigning a “resource” value to each team based on the number of overs remaining and the number of wickets in hand. This resource value represents the potential runs a team can score with the remaining resources.
Table 1: Resource Values
| Overs Remaining | Wickets Remaining | Resource Value |
|---|---|---|
| 50 | 10 | 100% |
| 40 | 10 | 80% |
| 30 | 10 | 60% |
| 20 | 10 | 40% |
| 10 | 10 | 20% |
| 5 | 10 | 10% |
| 0 | 10 | 0% |
When a match is interrupted, the DLS method calculates the revised target score for the team batting second based on the following factors:
- Resources available to the team batting first: This is calculated based on the number of overs they faced and the number of wickets they lost before the interruption.
- Resources available to the team batting second: This is calculated based on the number of overs they have remaining and the number of wickets they have in hand.
The DLS method then adjusts the target score for the team batting second to reflect the difference in resources available to both teams.
Example of DLS Method in Action
Let’s consider a hypothetical scenario:
- Team A bats first and scores 200 runs in 40 overs.
- Rain interrupts the match, and Team B has only 30 overs to chase the target.
Using the DLS method, we can calculate the revised target for Team B as follows:
- Calculate the resources available to Team A: Based on Table 1, Team A had 80% of their resources available (40 overs out of 50).
- Calculate the resources available to Team B: With 30 overs remaining, Team B has 60% of their resources available.
- Calculate the target score for Team B: The DLS method will adjust the target score based on the difference in resources available to both teams. In this case, Team B has 75% of the resources that Team A had (60% / 80% = 0.75). Therefore, the revised target for Team B would be 200 x 0.75 = 150 runs.
Advantages of the DLS Method
- Fairness: The DLS method aims to ensure a fair result in a rain-affected match by taking into account the resources available to both teams.
- Consistency: The DLS method provides a consistent and objective way to calculate revised target scores, eliminating the need for subjective judgment.
- Transparency: The DLS method is transparent and publicly available, allowing fans and commentators to understand how the revised target score is calculated.
Disadvantages of the DLS Method
- Complexity: The DLS method can be complex to understand, especially for casual fans.
- Unpredictability: The DLS method can sometimes lead to unpredictable results, especially in matches with significant interruptions.
- Controversies: The DLS method has been the subject of controversy on occasion, with some arguing that it does not always produce a fair result.
Frequently Asked Questions (FAQs)
1. What happens if the match is abandoned before the team batting second starts their innings?
If the match is abandoned before the team batting second starts their innings, the result is usually declared a no result.
2. Can the DLS method be used in T20 matches?
Yes, the DLS method is used in both ODI and T20 matches.
3. How does the DLS method account for wickets lost?
The DLS method assigns a resource value to each wicket lost, reflecting the impact on the team’s ability to score runs.
4. Can the DLS method be used in test matches?
No, the DLS method is not used in Test matches. Test matches are typically played over five days, and rain interruptions are less likely to significantly affect the outcome of the match.
5. What happens if the team batting second reaches the revised target before the allotted overs?
If the team batting second reaches the revised target before the allotted overs, they win the match.
6. What happens if the team batting second fails to reach the revised target within the allotted overs?
If the team batting second fails to reach the revised target within the allotted overs, the team batting first wins the match.
7. Is the DLS method perfect?
The DLS method is not perfect, and it can sometimes lead to controversial results. However, it is the best available method for calculating revised target scores in rain-affected matches.
8. How can I learn more about the DLS method?
You can find more information about the DLS method on the official website of the International Cricket Council (ICC).
