Innings in Cricket

An innings is simply the period in a cricket match when one team takes its turn to bat while the other bowls and fields. It is the core building block around which all cricket formats—Test cricket, ODI, and T20—are structured.

Think of an innings as a chapter of a cricket match. Some formats have one chapter per team, others have two. But every chapter follows the same basic pattern: one team bats, one team bowls, and the match progresses based on runs and wickets.

Quick TL;DR: An innings is the phase of a cricket match where one team bats until they are all out, overs run out, or the target is reached.

What Is an Innings in Cricket? (Core Definition)

Cricket’s official rule book—the Laws of Cricket—defines an innings as a team’s turn to bat. An innings ends only when certain conditions are met. The word “innings” may refer to a team innings or an individual player’s batting effort.

Official Definition According to ICC Laws

The ICC Laws of Cricket (Law 13) state that an innings begins when the umpire calls “Play” and ends when a team is dismissed, declares, forfeits, exhausts its overs, or reaches the target.

Inning vs Innings (Grammar & Usage)

A common confusion is whether the word is inning or innings. Cricket always uses the word innings for both singular and plural forms.

Correct: He played a great innings.
Correct: The match had four innings.
Incorrect: He played a great inning.

Why Cricket Uses “Innings” for Both Forms

The term comes from older English usage where “innings” meant “a turn or opportunity”. Over time, cricket adopted the word as-is.

Origins & History of the Term “Innings”

The first recorded usage of the term dates back to the 18th century. It originally referred to a player’s “turn at the crease” and later expanded to represent a team’s entire batting period. Understanding its history highlights how traditional cricket terminology is compared to modern sports.

How an Innings Works in Cricket

The fundamental idea is simple: one team bats to score runs while the other bowls to restrict runs and take wickets. But the innings structure has several components.

The Role of the Batting Team

The batting team’s goal is to score as many runs as possible. Two batters are always at the crease, and they rotate strike after singles, boundaries, or the end of an over.

The Role of the Bowling Team

The bowling team tries to take 10 wickets, stop scoring, apply pressure, and control the run rate. Bowlers deliver overs, and fielders support them by stopping runs and taking catches.

Innings Structure: Overs, Wickets & Runs

Three elements shape every innings:

Overs: Six legal deliveries make an over. Limited-overs formats have a fixed number of overs (20 or 50).
Wickets: A team becomes all out after losing ten wickets.
Runs: Runs can be scored through running, boundaries, extras, or overthrows.

Beginning of an Innings

An innings starts when the umpires call “Play”. The first ball marks the beginning of the scoreboard.

How an Innings Ends (All Possible Scenarios)

Unlike many sports that have time-based endings, an innings can have multiple ending conditions.

1. All-Out (10 Wickets Lost)

When ten batters are dismissed, the innings ends automatically.

2. Overs Completed in Limited-Overs Cricket

In ODI (50 overs) and T20 (20 overs), the innings ends when overs run out.

3. Target Reached During a Run Chase

If the batting team reaches the target, the innings ends early.

4. Declaration by the Captain

In Test cricket, a captain can end an innings voluntarily to gain strategic advantage.

5. Forfeiture of Innings

Rare, but a team can concede their innings under special conditions.

6. Retired Hurt or Retired Out Cases

Unique situations involving injured players, though these don’t always end an innings alone.

7. Match Abandonment (Weather or Light)

Rain or bad light may end an innings prematurely.

8. Time Limit Ending (In Multi-Day Matches)

If time runs out, the innings ends, and the match may result in a draw.

Number of Innings by Cricket Format

This is where innings differ widely.

Below is a clear table explaining innings per format:

Format	Overs Per Innings	Innings Per Team	Total Innings Possible
Test Cricket	Unlimited overs	2 innings per team	4 innings
First-Class	Unlimited	2	4
ODI	50 overs	1	2
T20	20 overs	1	2
T10	10 overs	1	2
The Hundred	100 balls	1	2

Test Cricket

ODI Cricket

The Hundred, T10 & Women’s Formats

These formats have the same single-innings structure but differ in balls/overs.

Split Innings Experiments

Some domestic leagues experimented with dividing the innings into two halves, but these formats didn’t gain global adoption.

First Innings vs Second Innings Comparison

In limited-overs cricket:

First innings sets the target.
Second innings chases the target.

In Test cricket:

First innings builds a foundation.
Second innings navigates pitch wear and longer-term strategy.

Tactical Differences

Impact of Pitch Conditions
