# Ball Mark Inspection (Clay Only)

\
Overview
--------

A Ball Mark Inspection (BMI) is an event that only happens on **clay** courts.

They work very similarly to challenges, a BMI happens when a line judge calls a ball and the team/player disagrees. The umpire will then come down to the court and take a look at the mark that the ball made on the clay, and judge if the ball was out or in.

## Packet

A BMI will occur at the same time as a challenge - After 'Point Started' and before the 'Point' packet.

It does not include information on if it was 'won' or 'lost' - just that there was a BMI. The next point is always the outcome of the BMI (who the point is awarded to).

An example from the French Open, 2024:

Followed by an "inProgress packet to indicate that the BMI is being carried out:
