The DLS method (Duckworth-Lewis-Stern) is a mathematical formulation designed to calculate the target score for the team batting second in a limited overs cricket match interrupted by weather or other circumstances. The DLS method is used to help decide the winning side in an unavoidable situation for the team batting second in limited-overs cricket. The basic principle is that each team in a limited-overs match has two resources available with which to score runs (overs to play and wickets remaining), and the target is adjusted proportionally to the change in the combination of these two resources. The DLS method is an attempt to set a statistically fair target for the second teams innings, which is the same difficulty as the original target. The target score in cricket matches without interruptions is one more than the score of the team batting first. The DLS method addresses both overs and wickets remaining as a resource and revises the target based on the availability of the resources. The par score is the total that a chasing team should have reached – when they are ‘X’ wickets down – at the time of interruption while the target score is the revised score that a team is required to get after an interruption. The target score is one fixed number, while the par score changes according to the number of wickets lost. The par scores are calculated before an interruption, while targets are calculated after an interruption.
