Follow on Calculation in Cricket

What is a Follow On in Cricket?

The follow-on is a tactical decision in Test cricket where the team batting second in the first innings is required to bat again after the first innings ends. This means they face the same bowling team that dismissed them in the first innings, which can be a significant psychological and physical challenge.

The decision to enforce a follow-on is typically made by the team batting second, and it's usually considered when the team is significantly behind in the match and believes they can make a comeback by batting again.

When is Follow On Used?

The follow-on is most commonly used in Test cricket when:

• The team batting second is significantly behind in the match
• The team batting second believes they can make a comeback by batting again
• The conditions of the match (weather, pitch, etc.) are favorable for batting
• The team batting second wants to test the bowling team's performance over a longer period

However, the decision to enforce a follow-on is a complex one, and it's not always guaranteed to be successful. The team batting second must carefully consider the current match situation and the potential impact of the follow-on before making the decision.

How to Calculate Follow On

Calculating whether a follow-on is advisable involves several factors, including the current match situation, the performance of the batting team, and the conditions of the match. One of the most commonly used methods for calculating the follow-on is the Duckworth-Lewis-Stern (DLS) method, which adjusts the target score based on the number of overs remaining and the resources available.

The formula above is a simplified version of the follow-on calculation. In practice, the decision to enforce a follow-on is based on a more complex set of factors, including the performance of the batting team, the conditions of the match, and the potential impact of the follow-on on the outcome of the match.

The DLS Method

The Duckworth-Lewis-Stern (DLS) method is a mathematical model used to adjust the target score in limited-overs cricket matches affected by weather or other disruptions. The method is also used to calculate the follow-on in Test cricket, where the target score is adjusted based on the number of overs remaining and the resources available.

The DLS method takes into account several factors, including the number of overs remaining, the number of wickets in hand, and the current run rate. The method is designed to ensure that the target score is fair and achievable, taking into account the current match situation and the resources available to the batting team.

Example Calculation

Let's consider an example to illustrate how the follow-on calculation works. Suppose the team batting second is chasing a target of 300 runs in 50 overs. The team has scored 150 runs in 20 overs, with 5 wickets in hand.

Using the simplified follow-on formula:

Since 3.75 is greater than 1.5, the team batting second would be advised to enforce a follow-on. However, the decision to enforce a follow-on is ultimately up to the team batting second, and it's based on a more complex set of factors, including the current match situation and the potential impact of the follow-on on the outcome of the match.
