It's going to be a one-set shootout between sixth seed Daniil Medvedev and world number 97 Adam Walton.

Medvedev has been incredibly inconsistent so far today but finds some big serves as he clinches the fourth set 6-1, and then leaves the court for a comfort break.

The momentum has continually swung from one player to the other in this match - who is going to seize it in the final set?

Aryna Sabalenka has competition for the top spot in the women's world rankings at Roland Garros.

Elena Rybakina has a chance to overtake Sabalenka - but she will need to reach the semi-final in order to have a chance.

If Sabalenka reaches the fourth round then Rybakina would need to reach the final, and if Sabalenka reaches the semi-finals then Rybakina will need to lift the title.

Here is what women's world number one Aryna Sabalenka had to say following her first-round victory over Spain's Jessica Bouzas Maneiro.

First, on coming into the net more during points: "That's the most enjoyable part of the game right now, that I'm able to come to the net and play points there. I'm so glad I have improved that part of the game and I can bring it on court.

"It is hot. Thanks so much for staying and don't forget to stay hydrated guys - its pretty hot out here."

Only playing as world number one: "I think we all feel pressure, that is just part of our lives, so I have just learned to ignore it.

"I am still trying to learn what is perfect for me. I enjoy if [the conditions are] cold and slow, hot and quick. I try to enjoy the game and do my best. Let's hope this is the perfect condition for me and it's going to help me."

Australian wild card Adam Walton races to a 40-0 lead on his serve but then sprays wide a wayward volley.

It proves costly with sixth seed Daniil Medvedev finally converting his fourth break point for a double break in a game that lasts over 10 minutes.

Now it's Queenslander Walton who is showing signs of frustration, slamming a ball down into the clay.

It's quite hot out there...
