What is DLS Full Form in Cricket?

DLS full form is Duckworth–Lewis–Stern method, 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. It is generally accepted to be the most accurate method of setting a target score.

The DLS method was devised by two English statisticians, Frank Duckworth and Tony Lewis, and was first used in 1997. In 2015, the method was updated by Australian academic Steve Stern, and its name was changed to the Duckworth–Lewis–Stern method.

The DLS method takes into account two factors: the number of runs scored by the team batting first and the number of overs remaining in the match. It also considers the number of wickets lost by the team batting first, as this can have a significant impact on their scoring rate.

The DLS method calculates a target score for the team batting second based on the following formula:

Target score = (Average score at par – Average score per wicket lost by the team batting first) * Overs remaining in the match

The average score at par is the average score that a team would score in a given number of overs, based on historical data. The average score per wicket lost is the average number of runs lost per wicket, based on historical data.

The DLS method is used to set a target score for the team batting second in both international and domestic limited overs cricket matches. It is also used in other sports, such as baseball and softball.

Advantages of the DLS method in Cricket

The DLS method has a number of advantages over other methods of setting a target score in rain-affected matches. These advantages include:

• It is a fair and objective method, as it is based on historical data.
• It is relatively easy to calculate, even without the use of a computer.
• It is flexible enough to be used in a variety of different match situations.

Disadvantages of the DLS method in Cricket

The DLS method also has some disadvantages, including:

• It can be complex and difficult to understand.
• It can be inaccurate in certain situations, such as when the team batting first has lost a lot of wickets early in the match.
• It can be difficult to implement in matches where the weather conditions are constantly changing.

Overall, the DLS method is the most accurate and reliable method of setting a target score in rain-affected limited overs cricket matches. It is used in all international and domestic limited overs cricket matches, and it is becoming increasingly popular in other sports as well.

Examples of the DLS method in use

Here are a few examples of the DLS method in use:

• In the 2019 Cricket World Cup final, England were batting first when the match was interrupted by rain after 24.1 overs. England had scored 222/2 at that point. The DLS method was used to calculate a target score of 241 runs for New Zealand, who had 49 overs to score them. However, New Zealand were only able to score 241 runs in 46.1 overs, and England won the match by one run.
• In the 2021 Indian Premier League, the match between the Delhi Capitals and the Sunrisers Hyderabad was interrupted by rain after 18.4 overs. The Delhi Capitals had scored 159/3 at that point. The DLS method was used to calculate a target score of 162 runs for the Sunrisers Hyderabad, who had 17.2 overs to score them. However, the Sunrisers Hyderabad were only able to score 157 runs in 17.2 overs, and the Delhi Capitals won the match by four runs.

These are just two examples of the many times that the DLS method has been used to determine the outcome of a rain-affected cricket match. The DLS method is a fair and accurate method of setting a target score, and it is an essential tool for the modern game of cricket.
