Serena Williams, who is looking for her 24th grand slam title, went out at Rod Laver Arena almost at the same time as the state of Victoria's Prime Minister announced that Melbourne and the rest of Victoria will be shut down for five days.

- I did not know about it until the match was over.

And it was good that I did not know about it.

It will be some tough days for everyone, I think.

But hopefully we will get through it, says Williams after his victory over Anastasia Potapova.

The shutdown comes after a new outbreak of the British variant of the coronavirus at a quarantine hotel at Melbourne Airport.

Serena Williams is ready for the fourth round after a 7-6, 6-2 victory against Anastasia Potapova.
