We could be seeing Katie Boulter in action very shortly.

In the match before hers on court eight, Hubert Hurkacz - after a blip in the third set - is 4-2 up in the fourth against Spain's Jaume Munar.

Yet another break for Amanda Anisimova and with a hold to 15, she's one game away from round two.

Tiantsoa Rakotomanga Rajaonah saved one break point to take the fifth game to deuce but has now lost her past six service games. She's serving to stay in the match.

Toby Samuel, speaking to BBC Radio 5 Live: "It's been an unbelievable experience for me this week. Being able to qualify for my first Grand Slam main draw is like a dream to come true and be able to play against such amazing players.

"Alex de Minaur in the first round - it's almost bittersweet because you want to try and go through as many rounds as possible but also getting to play somebody like that is really eye-opening for your own game and unbelievable experience.

"Super happy to be able to share this moment with my family, coaches and friends as well."

So, it wasn't to be for Toby Samuel, who was the only Briton to make it through the three rounds of French Open qualifying.

He's got a first Grand Slam main draw match under his belt now, so it will be exciting to see what's next for the 23-year-old. A Wimbledon wildcard perhaps?

Here's what he had to say after his defeat by Alex de Minaur earlier today...

Amanda Anisimova, muttering to herself in between points, fights back from 15-40 and comes through four deuces, including saving two more break points, to take a 3-1 lead in the second set.

Huge hold for the sixth seed.

Two-time French Open finalist Casper Ruud has started well over on Court Simonne-Mathieu. He's a set to the good against Russian qualifier Roman Safiullin.

The Norwegian 15th seed has had a decent clay-court swing so far, reaching the final in Rome along with a semi-final run in Geneva.

Oh, it's all getting chaotic again on Court Suzanne-Lenglen.

Tiantsoa Rakotomanga Rajaonah converted her first break point to put the set back on serve but Amanda Anisimova has immediately restored her advantage.

At 15-40, the French wildcard had to have a couple of attempts at her toss and when she eventually got her serve over the net, the American brought a brief rally to an abrupt end with a forehand winner.

After coming through qualifying to make his Grand Slam singles main draw debut, Great Britain’s Toby Samuel, 23, lost in three sets to Australian eighth seed Alex de Minaur 6-4 6-4 6-2.

At the opposite end of the career spectrum, former champion Stan Wawrinka said farewell to Roland Garros in the first round, losing to Jesper De Jong in four sets.

Czech Jiri Lehecka is Monday's biggest casualty in the men’s draw, with the 12th seed losing in straight sets to Pablo Carreno Busta, but fellow seeds Frances Tiafoe, Arthur Rinderknech, Rafael Jodar and Brandon Nakashima have all reached round two.

Four-time women’s champion Iga Swiatek lost just three games as she crushed Australian teenager Emerson Jones in straight sets while second seed Elena Rybakina was similarly ruthless in her 6-2 6-2 win over Veronika Erjavec.

Seventh seed Elina Svitolina fought back from a set down to beat Anna Bondar in a third-set tie-break while Italian Jasmine Paolini, Belgium’s Elise Mertens and Austria’s Anastasia Potapova also advanced.

Make that five consecutive games for Amanda Anisimova, who opens the second set with a break to love.

She's had 10 break points in the match and converted four of them.

That's four games on the spin for Amanda Anisimova as she takes the first set 6-3.

Tiantsoa Rakotomanga Rajaonah saved two break points to force deuce in game eight but couldn't deny the American at the third time of asking.

Anisimova then breezed through a hold to love - she's only given away one point in her past two service games.

Rakotomanga Rajaonah only held serve once in the first set.

We're hoping it's not too much longer before we can bring you live coverage of British number three Katie Boulter's opening match against Akasha Urhobo.

The match before that contest on court eight between Hubert Hurkacz and Jaume Munar has gone to a fourth set, after Munar pulled one back to stay alive.

On Court Suzanne-Lenglen, sixth seed Amanda Anisimova has a battle on her hands against French wildcard Tiantsoa Rakotomanga Rajaonah.

They exchanged four consecutive breaks of serve but the American appears to have wrestled back a bit of control, following up her break to love with a hold to 15.

Although Stan Wawrinka will not retire until October's Swiss Indoors tournament in Basel, this was a fond farewell to the venue he believes witnessed the best match of his life.

Back in 2015, Wawrinka unleashed a ferocious barrage on Novak Djokovic as he won the title from a set down to force Djokovic to wait another year to complete the career Grand Slam.

"Because it was Roland Garros and it was the final against Djokovic - number one at that time. I believe it was the best [match] of my life," Wawrinka, 41, told BBC Sport at Roland Garros.

It's always difficult to compare across the eras but if we're going to go on Grand Slams, where many players go through their careers without winning any, Wawrinka's got three out of the four. The only one he didn't win was Wimbledon so I think he's had a fantastic career.

You also have to look at his wins when he won those slams, he had to beat the very best names in our sport; Djokovic, Nadal, all these great champions.

I will remember him for just the spectacular shot-making and the ability to bring a crowd with roars to their feet. He's like a lumberjack with an axe in his hand thumping down his winners.

A 66th main draw match at Roland Garros - and done.

Only five men have played more singles matches at the French Open in the modern era than Stan Wawrinka.

They are greats Novak Djokovic (119), Rafael Nadal (116), Roger Federer (90), Guillermo Vilas (74) and Andre Agassi (67).

How does Svitolina do it? I have nothing but admiration for this woman who is quite extraordinary.

We saw her doubled over quite a few times over the course of this match, her back up against the wall, she was on the ropes and her opponent really played such smart tennis but she's just such a fighter. The way she grits and gets the ball back into play, asks lots of questions and physically grinds down an opponent in the way that she did.

Bondar just disappeared [in the tiebreaker], far too many unforced errors and she has to be bitterly disappointed.

One of Stan Wawrinka's final wishes before leaving the court was to call on the crowd to support friend Gael Monfils, who was among the players to feature in Wawrinka's tribute video, as he too contests the final French Open of his career - beginning with a match against compatriot Hugo Gaston in tonight's night session on Court Philippe Chatrier.

Elina Svitolina on what she will say to her husband Gael Monfils before he potentially plays his last-ever match at Roland Garros this evening: "Well, I will tell him to try to enjoy his last moment here on this court. I think he always brings the best show.

"We're lucky people to experience his last dance at Roland Garros. I am very lucky to be by his side.

"It is going to be another show and I cannot wait to be there supporting him."

Here's what women's seventh seed Elina Svitolina had to say, speaking after winning a three-set thriller against Anna Bondar: "Definitely the support of you guys was unbelievable and this kind of battle is never easy but of course I am pleased with the performance. I have played her many times and I am tired to play against her.

"It was an amazing match, I'm very pleased with my performance and really overwhelmed with emotions. A first round like this is nice, it puts your mind back on track, back working."

On what got her through a 14-minute game at the start of the third set: "Mental strength firstly, and secondly, my physical conditions. Thanks to my fitness coach over there for making me the athlete I am now.

"This kind of battle, there's lots of emotion, lots of tension and you just need to be focused one point at a time. She was playing incredible so I had to stay tough and bring my best game."
