How to Calculate Follow on Runs in Test Cricket

In Test cricket, a follow-on is a strategic decision where the team that won the toss and batted first is required to bat again after the second team has declared their innings. This occurs when the team batting first scores fewer runs than the team batting second, and the difference between the two scores is less than the number of days remaining in the match.

What is a Follow On in Test Cricket?

A follow-on is a unique situation in Test cricket where the team that won the toss and batted first is forced to bat again after the second team has declared their innings. This happens under specific conditions:

The team batting first scores fewer runs than the team batting second
The difference between the two scores is less than the number of days remaining in the match
The team batting second has a lead that is not large enough to win the match without the first team batting again

When a follow-on is declared, the team that batted first must bat again with the same number of innings remaining. The team that batted second will then have the opportunity to declare their innings and potentially win the match.

How to Calculate Follow On Runs

Calculating follow on runs involves determining the target score that the team batting first must reach to avoid a follow-on. The formula is based on the difference between the two teams' scores and the number of days remaining in the match.

Follow On Formula

Follow On Runs = (Team 2 Score - Team 1 Score) - (Days Remaining × 100)

If the result is positive, a follow-on is declared.

The ICC Test Match Regulations specify that a follow-on is declared if the difference between the two teams' scores is less than the number of days remaining in the match multiplied by 100 runs. This creates a target score that the team batting first must reach to avoid being forced to bat again.

Note: The 100-run multiplier is based on the average scoring rate in Test cricket, which is approximately 100 runs per day.

Example Calculation

Let's look at an example to illustrate how follow on runs are calculated:

Scenario

Team A (batting first) has scored 250 runs
Team B (batting second) has scored 320 runs
There are 2 days remaining in the match

Calculation

Using the follow on formula:

Follow On Runs = (320 - 250) - (2 × 100) = 70 - 200 = -130

Since the result is negative (-130), a follow-on is not declared in this scenario.

Alternative Scenario

Let's consider another example where a follow-on might be declared:

Team A has scored 350 runs
Team B has scored 420 runs
There is 1 day remaining

Calculation:

Follow On Runs = (420 - 350) - (1 × 100) = 70 - 100 = -30

Again, the result is negative, so no follow-on is declared.

For a follow-on to be declared, the difference between the two scores must be less than the number of days remaining multiplied by 100 runs. In most cases, this requires a very small difference in scores and a limited number of days remaining.

FAQ

What is the purpose of a follow-on in Test cricket?: The follow-on is a strategic decision that allows the team batting second to declare their innings and potentially win the match, while forcing the team batting first to bat again if they cannot reach the required target.
How is the decision to declare a follow-on made?: The decision is based on the difference between the two teams' scores and the number of days remaining in the match. If the difference is less than the number of days remaining multiplied by 100 runs, a follow-on is declared.
Can a team refuse to declare a follow-on?: No, the follow-on is a decision made by the match officials based on the scores and the number of days remaining. Teams cannot refuse to follow the rules of Test cricket.
What happens if a follow-on is declared?: The team that batted first must bat again with the same number of innings remaining. The team that batted second will then have the opportunity to declare their innings and potentially win the match.
Is the follow-on rule the same for all Test matches?: Yes, the follow-on rule is consistent across all Test matches and is governed by the ICC Test Match Regulations. The formula and conditions for declaring a follow-on remain the same in every Test match.
