Still no sign of Victoria Azarenka. The second set finished almost 10 minutes ago.

The umpire is on the walkie talkie. Naomi Osaka is shaking her legs out and bobbing up and down by the net.

Naomi Osaka is first to reemerge onto Court Suzanne Lenglen. She has taken a new racquet out of her bag too.

It looks like both Naomi Osaka and Victoria Azarenka have gone for a breather at the end of that marathon second set.

Who can blame them?

This match has already gone on for over two hours and we've got another set to come.

Dominic Thiem has restored his lead against Alexander Bublik of Kazakhstan on Court Philippe Chatrier.

The fourth-seeded Austrian took the opening set, lost the second on a tie-break but has won the third 6-3.

The winner takes on Pablo Cuevas.

Not this time! Current world number one Naomi Osaka takes the second set against the former world number one on her fourth set point.

We have a belter of a deciding set coming up.

Fourth time lucky for Osaka?

Azarenka is going to have to save another set point.

Victoria Azarenka is solid as a rock when down set point! Naomi Osaka can't get through. Again Azarenka comes to the net but this time she makes the volley.

Deuce again.

*Groans*.

Double fault from Azarenka. A third set point for Osaka.

Osaka misses again. She isn't one to hide her disappointment. Deuce.

One set point saved by Azarenka.

She comes in to the net to surely win the following point...

No! An almighty scream tells you the ball has hit the net.

Here's another set point for Osaka.

Osaka crunches a booming winner. She waves her fist.

This is a set point for the world number one...

Osaka trailed by a set in the first round. She's already had to do this once.

Azarenka's screams turn into a groan as a forehand hits the net.

30-30.

There's a thriller going on over on Lenglen so let's concentrate on that.

World number one Naomi Osaka has held serve to make it 6-5 in the second set. She was 4-2 down remember and already trails by a set against Victoria Azarenka.

Can Azarenka take it to a tie-break?

Had it been one set all, maybe he would have continued, but with the grass court season coming up it is probably a sensible decision but a shame to see.

That means Johanna Konta is the only British representative in the singles at the French Open.

We'll bring you news of Kyle Edmund's injury as soon as we get it.

All over. Kyle Edmund calls it a day. He wanders over to Cuevas when he returns and apologetically says he can't continue.

We will see shortly what the problem is.

Ah, all becomes clear. Edmund has called the trainer. The medical man crouches down in front of the Brit to see what the problem is.

He doesn't look too well to me, but is also sharply extending his leg, almost as though he is saying he's tweaked something in his knee.

Kyle Edmund is getting some treatment meanwhile at the change of ends...

Naomi Osaka drops at the knees so her backside is almost dirtied by the red clay. She misses a forehand and that allows Vika Azarenka to hold serve. The world number one has hit 24 unforced errors today. Azarenka has only made 13 in comparison.
