A set had been played in the semifinal between Daniil Medvedev and Russian Andrey when Medvedev crashed into the TV camera - which overturned.
The 25-year-old was noticeably annoyed by the placement of the camera.
And after setting it up again, the star chooses to kick it.
- Do not do that, says the judge.
Of which the 25-year-old answers: "I almost broke my hand".
After the incident, Medvedev needed a shorter medical time-out and he eventually lost the semifinals 2-6, 6-3, 6-3.
