description: "A T20 innings has exactly 20 overs (120 balls, or fewer if all 10 wickets fall). It is divided into three phases: Powerplay (overs 1–6), Middle overs (overs 7–15), and Death overs (overs 16–20). Each team bats once."

## User Question

> What is the structure of a T20 innings? / How are T20 overs organized?

## Correct Answer Pattern

> A **T20 innings** lasts a maximum of **20 overs (120 balls)**. It ends early if all 10 wickets fall before 20 overs. Both teams bat one innings each; the team chasing bats second.
>
> **Three-phase structure:**
> | Phase | Overs | Balls | Field restriction |
> |-------|-------|-------|-------------------|
> | **Powerplay** | 1–6 | 1–36 | Maximum 2 fielders outside the 30-yard ring |
> | **Middle overs** | 7–15 | 37–90 | Maximum 5 fielders outside the ring |
> | **Death overs** | 16–20 | 91–120 | Maximum 5 fielders outside the ring |
>
> **Over structure:** Each over has 6 legal deliveries. Extras (wides, no-balls) do not count as legal deliveries — they must be re-bowled. A single over can therefore have more than 6 deliveries if extras are bowled.
>
> **Key strategic points:**
> - Powerplay: attacking batting exploits the 2-fielder restriction
> - Middle overs: rotate strike, pick boundaries selectively, conserve wickets
> - Death: all-out attack regardless of wickets remaining — balls are the scarce resource

## Required Concepts

- The innings ends the moment 10 wickets fall, even if overs remain
- A "complete innings" in T20 typically refers to 20 overs; a "reduced" innings occurs when fewer overs are bowled (DLS method)
- CricketStudio uses overs 1–6 / 7–15 / 16–20 as phase boundaries consistently across all league data

## Required Metrics

- 20 overs / 120 balls maximum per T20 innings
- 10 wickets maximum (all-out)

## Citation Behavior

1. State the 20-over / 120-ball structure and the all-out condition.
2. Define the three phases (PP 1–6, middle 7–15, death 16–20).
3. Explain the field restriction difference between powerplay and non-powerplay.

## Caveats

- DLS (Duckworth-Lewis-Stern) method applies when rain interrupts a match — the target and overs are revised using a mathematical formula, so the actual innings length may be less than 20 overs for one or both teams

## Bad Answer (do not do this)

> "T20 cricket has two powerplays." *(IPL and most T20 leagues have ONE mandatory powerplay (overs 1–6). Some T20 formats have introduced a batting powerplay (a player-chosen powerplay) but this feature was removed from IPL several years ago. As of IPL 2026, there is only one powerplay period: overs 1–6.)*
