The Duckworth-Lewis-Stern (DLS) method is a mathematical formula used in cricket to adjust the target score for the team batting second in a rain-affected limited-overs match. It was introduced in 1997 as a replacement for the previous rain rule, which was deemed to be unfair and inconsistent.

In a limited-overs match, each team gets a fixed number of overs to bat, typically 50 overs in One Day Internationals (ODIs) and 20 overs in Twenty20 Internationals (T20Is). However, in case of rain interruptions, the number of overs can be reduced, and this is where the DLS method comes into play.

The DLS method takes into account several factors to calculate the revised target score for the team batting second. These factors include the number of overs remaining, the resources available (wickets in hand and balls remaining), and the scoring patterns of teams in similar situations in the past.

The method works by creating a par score, which is the score that a team should be at a given stage of their innings if they were to achieve a winning percentage of 50%. This par score is then adjusted based on the number of overs remaining and the resources available.

For example, if a team has batted for 20 overs and scored 100 runs with the loss of 2 wickets, and rain interrupts the match, the DLS method will calculate the par score for that stage of the innings. If the par score is 120 runs, and the team batting second resumes their innings after the rain delay with 30 overs remaining, the revised target will be calculated based on the par score and the remaining overs.

The DLS method also takes into account the concept of "resources" in a limited-overs match. Resources refer to the number of wickets in hand and the number of balls remaining. The method considers that a team with more wickets in hand and more balls remaining has a higher chance of achieving the target, and adjusts the revised target accordingly.

The DLS method has evolved over the years to become more accurate and fair. Initially, it faced criticism for producing unrealistic targets and favoring the team batting second. To address these concerns, the method was refined and a new version called the DLS method was introduced in This version, named after Frank Duckworth and Tony Lewis (the original creators of the method) along with Steven Stern (who made further improvements), is considered to be more accurate and fair.

The DLS method has become an integral part of limited-overs cricket, ensuring that rain-affected matches have a fair outcome. It has been used in several high-profile matches, including World Cup finals, and has been widely accepted by players, officials, and fans.

In conclusion, the DLS method is a mathematical formula used in cricket to adjust the target score for the team batting second in a rain-affected limited-overs match. It takes into account various factors such as the number of overs remaining, resources available, and scoring patterns to calculate a revised target. The method has evolved over the years to become more accurate and fair, ensuring that rain-affected matches have a fair outcome.
