What is DLS method in cricket?
The DLS method, which stands for the "Duckworth-Lewis-Stern" method, is a mathematical system used in limited-overs cricket matches (such as One Day Internationals and Twenty20 matches) to adjust the target score for the team batting second in rain-affected matches. The DLS method was introduced as an improvement to the earlier Duckworth-Lewis method, incorporating the contributions of Frank Duckworth, Tony Lewis, and Steven Stern.
The primary purpose of the DLS method is to provide a fair and equitable method for recalculating the target score for the team batting second when overs are lost due to rain or other disruptions. It takes into account the number of overs bowled, the number of wickets lost, and the scoring patterns up to the interruption to establish a revised target.
Key components of the DLS method include:
1. Resource Percentage: This is a measure of the resources available to a team, taking into account the number of overs bowled and wickets lost.
2. Par Score: The par score is the number of runs a team should aim to reach at a particular stage of the innings based on the available resources.
3. Target Score: The target score is adjusted according to the resources and is the goal for the team batting second to win the match.
The DLS method is applied using a software program that takes various factors into account and calculates the revised target score based on a combination of past scoring patterns and statistical analyses.
The DLS method has been widely accepted in international and domestic limited-overs cricket to ensure that matches affected by rain or adverse weather conditions have a fair and adjusted target for the team batting second to chase. It has added a level of consistency and accuracy to such scenarios, making it more equitable for both teams.
