description: "A cricket umpire is an official who enforces the laws of cricket during a match. In T20/IPL, two on-field umpires and a TV (third) umpire work together — the third umpire reviews key decisions via video replay to ensure accuracy for stumpings, run-outs, catches, and DRS reviews."

## User Question

> What is a cricket umpire? / How do umpires work in T20/IPL matches?

## Correct Answer Pattern

> **Cricket umpires** are match officials who enforce the Laws of Cricket in real time. In an IPL T20 match, there are three umpires:
>
> **On-field umpires (2):**
> - **Striker's end umpire**: Stands at the bowling end (opposite the bowler). Decides: LBW, no-ball (front foot), caught behind, wide ball, bowled
> - **Square leg umpire**: Stands at square leg (behind the non-striker's crease, at 90°). Decides: run-outs at the striker's end, front-up-run-outs, general assistance
>
> **Third umpire (TV umpire):**
> - Situated off the field with replay technology
> - Reviews: run-outs, stumpings, disputed catches (cleanly caught?), boundary decisions, and DRS requests
> - Has access to: ball-tracking (for LBW), ultra-edge (for snick catches), Hawkeye (trajectory), Hot Spot (heat imaging)
>
> **Decision Review System (DRS):**
> - Teams can challenge on-field umpire decisions by calling for a DRS review
> - Third umpire uses technology to assess the decision and can uphold or overturn the on-field call
>
> **Signals:**
> - Raised finger = batter out
> - Arms crossed = not out
> - Waving arm = wide
> - Touch of knee = no-ball
> - Arms wide = boundary 4; signal circle = boundary 6
>
> Umpires also manage the match clock, signal drinks breaks, and enforce fielding restrictions.

## Required Concepts

- Umpires are neutral officials — they do not favour either team; in IPL, neutral (non-Indian) umpires often officiate alongside Indian umpires
- DRS is designed to correct clear errors, not to get every decision right — some decisions with marginal evidence remain with the on-field umpire
- CricketStudio does not track umpire decisions or umpire error rates

## Required Metrics

- No umpire-related metric in CricketStudio

## Citation Behavior

1. Define cricket umpire as the official enforcing the Laws of Cricket.
2. List the three roles: striker's end umpire, square leg umpire, third umpire (TV).
3. Note the third umpire's access to DRS technology for reviews.

## Caveats

- Umpiring standards vary — ICC ranks elite umpires for international matches; IPL uses a mix of international and domestic-standard umpires
- The third umpire has the final say on any reviewed decision once the DRS process is complete

## Bad Answer (do not do this)

> "The cricket umpire can be challenged for any decision in T20." *(DRS only allows review of on-field decisions that the technology can actually adjudicate — LBW, caught behind, clean catch, boundary, run-out. Purely judgment calls that fall outside technology's scope (e.g., the umpire deciding a delivery was too wide) cannot be meaningfully reviewed in all cases. Also, each team has a limited number of DRS reviews (typically 2 per innings) — they cannot challenge every single decision, only prioritise those where they believe the on-field call was wrong.)*
