What is DSR and How it’s Working in Cricket

I’m not aware of this DSR Method. Later, I joined cricket club I know about it because of my co-players they are professional. So, today my article is about DSR and How it’s Working in Cricket. 

DSR, or the Duckworth-Lewis-Stern method, is a mathematical formula used in cricket to calculate the target score for the team batting second in a match that has been interrupted by rain or other external factors. The system was developed in the late 1990s by Frank Duckworth and Tony Lewis, and later modified by Steven Stern to make it more accurate and adaptable. 

In cricket, a limited-overs match consists of two innings, with each team batting for a specific number of overs, typically 50 overs in One Day Internationals (ODIs) and 20 overs in Twenty20 matches. However, weather conditions such as rain or bad light can often interrupt play, causing delays or even forcing the match to be abandoned altogether. When this happens, the DRS system is used to determine a revised target score for the team batting second to make the match fair and competitive. 

The DRS system considers various factors such as the number of overs remaining, the number of wickets lost, and the run rate of the team batting first at the time of the interruption. It uses a complex algorithm to calculate a revised target score that takes into account the reduced number of overs available to the team batting second and the loss of wickets during the interruption. 

The basic principle of the DRS system is to ensure that the team batting second has a fair chance to win the match, even if the match has been shortened due to external factors. The revised target score is calculated based on the principle that the team batting second should have a run rate equivalent to that of the team batting first, but with a reduced number of overs. This is designed to make the match fair and competitive for both teams, regardless of the circumstances. 

To illustrate how the DRS system works, let's take an example of an ODI match between India and England, where India has scored 300 runs in 50 overs, and England is batting second when rain interrupts play after 20 overs, with the score at 100 for 2 wickets. 
The DRS system would use a complex algorithm to calculate a revised target score for England based on various factors such as the number of overs remaining, the number of wickets lost, and the run rate of the team batting first at the time of the interruption. In this case, the DRS system would calculate the revised target score for England as follows: 

First, the DRS system calculates the run rate of the team batting first, which is 300 runs in 50 overs, or 6 runs per over. 

Second, the DRS system calculates the run rate required by the team batting second to win the match, based on the reduced number of overs available. In this case, England has 30 overs left, so the required run rate would be 201 runs in 30 overs, or 6.7 runs per over. 

Third, the DRS system adjusts the revised target score based on the number of wickets lost by the team batting second. In this case, England has lost 2 wickets, so the revised target score would be reduced by a certain number of runs to compensate for the loss of wickets. 
Once the revised target score has been calculated, the match can continue with England batting with the revised target score in mind. If England achieves the revised target score within the remaining number of overs, they win the match. If they fail to reach the revised target score, they lose the match. 
In conclusion, the DRS system is an important tool in cricket that ensures a fair and competitive match even in the event of interruptions or delays caused by external factors such as rain or bad light.
