Imagine yourself as a team coach for cricket who prepares the team for a crucial match against a challenging opponent. In this process, as a researcher, you've also gathered different types of data, including player statistics, pitch conditions, and match history, and suddenly, guess what? All your data gets scattered and messed up. Just imagine what you'll do in this overwhelming condition.
Here, the DLS method might help you to devise the perfect strategy. Sounds amazing, right? You might be wondering what this DLS method in cricket is. Or how to calculate it? So, the answer to all these is here in this blog, where I have shared everything about the DLS method in cricket. Let's dive in.
What is the DLS method in cricket?
The DLS method, popularly known as the Duckworth-Lewis-Stern method, is a mathematical calculation used to calculate the score of a cricket match, especially when the rain interrupts the match. The DLS method ensures that results are recalculated and reveals a fair target score for the team, which is batting second, based on the number of overs they have left and the wickets they've lost.
Suppose the match is interrupted by the rain instead of continuing where they left off. In that case, the DLS method is even more helpful in setting a new target that reflects the reduced time or resources available so the game can be more balanced. However, with several sports technology advancements and developments, the DLS method came into existence to check the accuracy and derive a proper calculation of the interrupted matches.
Who invented the DLS method?
Two British statisticians, Frank Duckworth and Tony Lewis, invented the DL or Duckworth-Lewis method. It was first used in the match played by Zimbabwe against England in 1996-1997, which won by seven runs and was officially approved by the ICC in 1999. After the Australian academic in 2015, Steve Stern updated the formula, and later, it was popularised as the Duckworth-Lewis-Stern method.
What is the use of the DLS Method in Cricket?
The DLS method is used to lay a proper set of scores for both the teams playing the match. In case when the overs are lost, it is difficult to set an adjusted target score, which is proportionally loss in overs, because a team that has 10 wickets in hand and 25 overs to bat can play more aggressively, more than if they have 10 wickets and full of 50 overs can consequently achieve higher rates.
The proper motive of the DLS method in cricket is to set a statistically fair target for the second team's innings, which is the same difficulty as the original target. In simple words, the basic principle is that each team, in a limited overs match, has two resources available to score runs, and the target is adjusted proportionally, changing in the combination of the following two resources.
History of the DLS method in cricket:
Several methods have been introduced in the history of Sports to resolve the issue of rain-affected cricket matches. But nothing was a success because of its intrinsic flaws, and they were also easily exploitable. So later, the DLS method was devised by two great British statisticians, Frank Duckworth and Tony Lewis.
In the 1992 Cricket World Cup, South Africa was knocked out of the match due to the rain against England; this triggered the need for a method to determine the targets or the outcomes of those teams in such situations. Hence, the DLS method came into existence. The DLS method was first introduced in international cricket on January 1, 1997, in the second Zimbabwe v/s England match, which Zimbabwe won by several runs.
The D/L method was adopted by the International Cricket Council in 1999, which was later adopted as the DLS method and as the standard method of calculating the target scores in rain-shortened one-day matches. This method was a better alternative to "Most Productive Overs," which was an utter failure.
How to Calculate the DLS method?
Later, the statisticians derived the proper way to calculate the score of the matches with the DLS method to derive a proper calculation. The DLS method involves the wickets and overs as resources and revises the target with the previous ones based on available resources.
However, the rate at which the resources deplete is not constant throughout the innings in the match, and as the resources consume faster, if the wickets are lost, more balls will be consumed. The DLS method calculates the total number of runs scored by both matches using the same resources.
In simple terms, the outcomes or the targets are decided with a similar formula as;
Team 2's Par Score =Team 1's Score x (Team 2's Resources/ Team 1's Resources). However, in international cricket, the values might not be publicly available for both teams; in such cases, they are derived from a computer program.
Are there any drawbacks to the DLS method?
Though it is a universal way of finding out the outcomes of the game that have been disturbed due to weather and other external factors, there are still some arguments regarding the authentication and accuracy of this method. Many critics criticise that the DLS method doesn't always reflect the specific dynamic of every game, but it relies on the assumption that the team utilises its resources optimally.
Drawbacks Of The DLS Method:
There are instances where it might produce a contradictory result. Because of its generalised model, it might not always reflect the specific nuances of every game.
The method assumes that the teams always use their resources optimally, which isn't always possible in the real world.
Yet, besides everything, the DLS method is universally accepted as the best alternative over others and remains a go-to mechanism for matches that have been cancelled due to external factors.
However, using the DLS method in cricket is necessary to calculate and derive nearly a conclusion for the outcomes of the matches interrupted due to weather. It helps to derive equitable outcomes by enhancing the game's integrity and excitement.
