Cricket is a well loved game by millions of people but sometime weather changes can disturb the game. During tournaments like Indian premium leugue IPL) the bad weather like storms or rain and bad light can affect the match and limit the team to complete its overs quota.Duckworth Lewis Stern method is used to maintain the target quota that makes the matches more fair and exciting.
Let’s know what is DLS how it works and how important it is for scoring in the IPL.
What Is the DLS Method?
DLS is a mathematical method to calculate the score target for a team who is batting second in a match like T20 that has limited overs and the game is disrupted by rain and stormy weather and unseen circumstances. Frank Duckworth and Tony Lewis were inventors of this formula in 1977 . Later on it was updated by Steven Stern and thus its name is Duckworth Lewis Stern (DLS) method.
Why Is the DLS Method Needed in IPL?
In normal gaming the team who bats second has to achieve one more run to reach the target than the other team who chooses batting first. But if match is interrupted by weather conditions the match and overs are lost and it is unfair for tram to expect the target in few overs and if the target runs are reduced in proportion to lost overs it is also not fair because team play aggressively if they have few overs.Thus the DLS method was introduced and is used to reach the fair and achievable target based on the available sources like overs and wickets to both teams.
What Does “Par Score” Mean in DLS?
The DLS par score stands for the number of runs the batting team must score at a particular point in their innings considering the number of overs and wickets left to be exactly level with the team that batted first. Par score helps to decide the victory of the team if the match is stopped and cannot be played again .
- If the chasing team has more than the par score then they will win.
- If they have less par scores the team batting first wins.
- If they are exactly at the par score the match is tied between both teams.
How Does the DLS Method Work?
The DLS method based on principle that a team’s ability to score runs depends on two key resources Over left to play and wickets remaining.
Wickets remaining
A team has 100% of its resources including all overs and all wickets at the start of the game. As the match progresses further these resources are used . If weather or rain interrupts the DLS method uses tables and calculations to work out how many overs and wickets (resources) are left and manage the target accordingly.
Example:
For instance if a team A bats first and scores 180 runs in 20 overs. Team B starts to play but after 10 overs rain reduces their innings to only 15 overs. The DLS method calculates how many runs Team B should score in 15 overs considering how many wickets they have lost to have the same chance of winning as Team A had in 20 overs.
Key Factors Considered by DLS
Overs Lost: How many overs were lost due to weather interruption.
Wickets Lost: How many wickets the team pursuing the target has lost at the time of interruption.
Stage of Innings: Losing overs at the end of an innings is more devastating for a team than at the start since teams score fast in the final overs.
How does the DLS Par Score affect the outcome of an IPL match?
The DLS par score directly affects the outcome of an IPL match when rain or interruptions reduce the number of overs available, especially during a run chase. The par score is the minimum runs the chasing team should have at a certain point (based on overs left and wickets lost) to be level with the team batting first. If play is stopped and cannot resume, the result is decided by comparing the chasing team’s score to the DLS par score at that moment:
- If the chasing team is ahead of the par score then they win.
- If they are behind the team who batted first will win.
- If both teams are exactly at par, the match is tied between them.
For instance in final IPL 2023 Gujarat Titans scored 214 runs with 4 out in 20 overs. Due to rainy weather Chennai Super Kings’ target was reduced to 15 overs and their new DLS calculated target became 171 runs. They reached 171runs with 5 out and 15 overs, so they won by 5 wickets using the DLS method.

Conclusion:
The DLS par score method in IPL is a significant part of cricket. It assures that rain or other foreseen interruptions do not unfairly affect the result of a game.
