What Is The Calculation for Follow on in Test Cricket

The follow-on decision in Test cricket is one of the most strategic moments in the game. It determines which team bats first and second in the second innings, with significant implications for the match outcome. This guide explains the calculation method behind the decision, the factors considered, and provides practical examples.

How the Follow On Decision is Made

The decision to impose a follow-on is made by the team that won the toss and chose to bat first in the first innings. The captain of the batting team must decide whether to enforce the follow-on based on the match situation, the pitch conditions, and the team's performance in the first innings.

The follow-on is typically imposed when the batting team has scored a substantial lead in the first innings, and the bowling team believes they can restrict the batting team to a lower total in the second innings. This strategy aims to level the playing field and create a more competitive contest.

Calculation Method

The decision to impose a follow-on is not based on a strict mathematical formula but rather on a combination of factors. However, the calculation can be conceptualized as follows:

Follow On Decision Formula

The decision to impose a follow-on is typically made when:

The batting team's first innings score is significantly higher than the bowling team's first innings score.
The bowling team believes they can restrict the batting team to a lower total in the second innings.
The pitch conditions and weather forecasts suggest that batting conditions will be challenging in the second innings.

While there is no precise formula, the decision is often based on the following calculation:

Follow On Decision Calculation

If (Batting Team's First Innings Score - Bowling Team's First Innings Score) > Threshold Value, then impose follow-on.

The threshold value is subjective and depends on factors such as the match situation, pitch conditions, and team strengths.

In practice, the decision is made by the captain of the batting team, who considers the above factors and their team's performance in the first innings.

Factors Considered

Several factors are considered when deciding whether to impose a follow-on:

1. First Innings Scores

The most significant factor is the difference between the batting team's first innings score and the bowling team's first innings score. A substantial lead often justifies the follow-on.

2. Pitch Conditions

The condition of the pitch is crucial. If the pitch is expected to deteriorate or become more challenging for batting in the second innings, the follow-on may be imposed to level the playing field.

3. Weather Forecast

Weather conditions, such as rain or overcast skies, can affect the decision. If the forecast suggests that batting conditions will be difficult in the second innings, the follow-on may be imposed.

4. Team Strengths

The strengths of the batting and bowling teams are considered. If the bowling team has a strong bowling attack and the batting team has a weak batting lineup, the follow-on may be imposed.

5. Match Situation

The overall match situation, including the number of wickets lost, the number of overs bowled, and the number of days remaining, is considered. A follow-on may be imposed if the match situation is favorable for the bowling team.

Example Calculation

Let's consider an example to illustrate the follow-on decision calculation:

Example Scenario

Team A bats first and scores 350 runs in the first innings. Team B, who bats second, scores 280 runs in their first innings. Team A, who won the toss and chose to bat first, now must decide whether to impose a follow-on.

The difference between the two first innings scores is 350 - 280 = 70 runs. If the threshold value for imposing a follow-on is set at 50 runs, then Team A would impose a follow-on because the difference exceeds the threshold.

However, the decision is not solely based on the numerical difference. Other factors, such as pitch conditions and team strengths, would also be considered. In this example, if the pitch is expected to deteriorate and Team B has a strong bowling attack, Team A might decide to impose a follow-on.
