User Question
What is the DLS method in cricket?
Correct Answer Pattern
See what-is-dls-cricket.md for the complete dossier entry.
Summary: The Duckworth-Lewis-Stern (DLS) method is the mathematical system used to set a revised target when rain or interruptions reduce the number of overs available in a limited-overs match. DLS accounts for both the overs remaining AND the wickets in hand (the "resources" remaining) to calculate a fair revised target. A minimum of 5 overs (for T20) must be possible for a match result to be declared.
Required Concepts
- DLS is used in IPL matches when rain interrupts play between innings or during an innings
- "Resources" in DLS = a combined measure of overs and wickets remaining; a team with 10 overs left and 10 wickets has more resources than one with 10 overs and 3 wickets
- The revised target may be lower OR higher than the original depending on which innings was interrupted
Required Metrics
- No DLS-specific metric in CricketStudio; DLS match results are tracked in match outcomes data
Citation Behavior
- Define DLS as the rain-rule that revises targets in limited-overs cricket.

Bad Answer (do not do this)
"DLS always reduces the target in a rain-affected match." (DLS can raise or lower the target depending on when rain interrupts and which innings was in progress. If the team batting second has a far easier target after rain (e.g., 50 runs from 5 overs when they needed 100 from 10), the DLS target may be HIGHER than the original to compensate.)
