The Duckworth-Lewis-Stern (DLS) method, with “DLS” standing for “Duckworth-Lewis-Stern,” is a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. The method was devised by two English statisticians, Frank Duckworth and Tony Lewis, and was formerly known as the Duckworth–Lewis method (D/L). It was introduced in 1997, and adopted officially by the ICC in 1999.
The DLS method works by assigning a “resource” value to each over of a cricket innings. This resource value takes into account the number of wickets that are in hand and the number of runs that have been scored. The team batting second is then assigned a target score that is proportional to their resources.
For example, if the team batting first scores 300 runs in 50 overs, then the team batting second would have a target score of 240 runs if they have 50 overs to bat. However, if the team batting second only has 40 overs to bat, then their target score would be reduced to 200 runs.
| Method Name | Duckworth-Lewis-Stern (DLS), formerly known as Duckworth–Lewis method (D/L) |
| Purpose | To calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances |
| Developers | Frank Duckworth and Tony Lewis |
| Introduction Year | 1997 |
| Official Adoption by ICC | 1999 |
| Calculation Basis | Assigns a “resource” value to each over of a cricket innings, taking into account the number of wickets in hand and the number of runs scored |
| Resource-Based Target Score | Team batting second receives a target score proportional to their available resources |
| Example Scenario | If the team batting first scores 300 runs in 50 overs, the team batting second would have a target score of 240 runs if they have 50 overs to bat. If the team batting second has only 40 overs to bat, their target score would be reduced to 200 runs. |
| Calculation Factors | – Number of overs bowled – Number of wickets lost – Runs scored – Current batting powerplay status – Fielding restrictions in place |
| Advantages | – Fair and objective method – Easy to understand and explain to spectators – Can be computed using a computer program – Successfully used in international cricket for many years |
| Disadvantages | – Can be complex to calculate, especially in real-time scenarios – Difficulty predicting the exact number of overs due to weather conditions – Application challenges in different match conditions (e.g., day/night or different pitches) |
The DLS method is a complex calculation, but it is designed to be as fair as possible to both teams. It takes into account the fact that a team with more wickets in hand and fewer overs to bat has a greater chance of scoring runs.
How is the DLS Method Calculated?
The DLS method is calculated using a computer program. The program takes into account the following factors:
- The number of overs that have been bowled
- The number of wickets that have been lost
- The runs that have been scored
- The current batting powerplay status
- The fielding restrictions in place
The program then calculates the resource value for each over of the innings. The team batting second is then assigned a target score that is proportional to their resources.
The DLS method is not perfect, but it is the best way to ensure that a fair result is achieved in a rain-affected cricket match.
Advantages of the DLS Method
The DLS method has several advantages over other methods of calculating target scores in rain-affected cricket matches. These advantages include:
- It is a fair and objective method that takes into account all of the relevant factors.
- It is simple to understand and explain to spectators.
- It is easy to calculate using a computer program.
- It has been used successfully in international cricket for many years.
Disadvantages of the DLS Method
The DLS method also has some disadvantages, such as:
- It can be complex to calculate, especially in real time.
- It is not always possible to predict the exact number of overs that will be bowled due to weather conditions.
- It can be difficult to apply the method to matches that are played under different conditions, such as day/night matches or matches played on different pitches.
Overall, the DLS method is a fair and objective way to calculate target scores in rain-affected cricket matches. It is simple to understand and explain to spectators, and it has been used successfully in international cricket for many years. However, it is important to be aware of the limitations of the method, such as its complexity and the difficulty of predicting the exact number of overs that will be bowled.
