Naomi Osaka's shock withdrawal from the French Open has raised questions over news conferences and their impact on mental health for athletes.

Osaka pulled out of Roland Garros on Monday, a day after tournament organisers fined the four-time grand slam champion and threatened her with more severe sanctions for refusing to attend mandatory media conferences.

The 23-year-old world number two and Japanese star had opened up about her mental health problems, revealing in a statement she has had "long bouts of depression" since claiming the 2018 US Open.

While her WTA and ATP Tour colleagues voiced their support, Osaka's stance has sparked controversy, though more importantly it has highlighted the growing issue of mental health problems in sport.

"I think it's a very important stance because it really highlights how sport has really looked at challenging issues through either the paradigm of sport or business," World Players Association executive director Brendan Schwab told Stats Perform. "Here, there is a very simple rule put in place that athletes have to attend post-match media conferences in order to promote visibility around the sport and then to promote the commercial interests of the sport. But that rule is put in place without any due diligence being done as to the risks with that on athletes or athlete health and safety.

"If we look at health and safety, we have to look at not only physical health but mental health and wellbeing. There is a very clear rule but it's going to impact athletes differently. The tournament organisers and sports bodies need to understand they have this proactive duty and to be aware of those impacts, and where their rule is going to have a harmful impact, they need to just adjust their procedures and requirements accordingly."

German great Boris Becker voiced his concerns for Osaka's future following her decision to quit the French Open in Paris.

A six-time slam winner, Becker told Eurosport: "I always believed the media was part of the job. Without the media, there is no prize money, no contracts, you don't get half the cake. I hated the media and I didn't like talking to journalists, but you had to do it.

"Now she is pulling out of the tournament altogether because she can't cope with it and that raises much bigger questions for me. If she can't cope with the media in Paris, she can't cope with the media in Wimbledon or the US Open. So I almost feel like her career is in danger due to mental health issues."

It is a view shared by many past and present tennis players – news conferences are part and parcel of the job. But are they?

"I think everyone would agree that is an important part of the job, but certainly not an essential part. The essential part of the job is performing as a player. But we cannot ask people to perform in circumstances where it's unsafe. It may be safe for some and unsafe for others," said Schwab.

"As in this case, there is an understanding that a particular player has a pre-condition or certain vulnerability, not to respond to that is inexcusable. It's certainly no defence to say it's safe for other people. That is why we need a real deep understanding of mental health.

"It's really important to see it as an occupational issue. A sporting place is not an ordinary workplace. It is a workplace which has heightened pressure. Therefore, the likelihood of there being adverse mental health impacts are greater. It's not going to affect everyone equally and sports bodies need to be smart enough to understand that fact."

Schwab added: "For Naomi's incredibly courageous stance here, there will be other players for which withdrawal is not an option and they will continue to face the workplace and pressures associated with that and therefore exacerbating the harm they're already experiencing."

The World Players Association is the leading voice of organised players in the governance of world sport. It brings together 85,000 players across professional sport through more than 100 player associations in over 60 countries.

As mental health becomes more prevalent in a professional sports environment amid the growing physical and emotional demands, Schwab said: "What our Players Associations do is they run player development and wellbeing programmes. The more sophisticated of those programmes would actually have employees and experts who are engaged by the player associations but often based in the teams or club environment, so the players know they can access them, they are proximate to the players so they can access tailored advice and support.

"Mental health is one of those things but there are many other issues that players will have to deal with. The athletic career itself is short-term and precarious, so there is constant effort being made to ensure players are developing holistically, they're pursuing education and other opportunities."

As Schwab voiced his disapproval of the "blanket rule" to post-match commitments, the Australian shed light on how the World Players Association prepares athletes for the media.

"Certainly part of our development programmes, we will provide what we call induction programmes so that the players go through what they will expect in terms of their athletic career, so they can excel as athletes and in the job," he said. "Clearly, dealing with the media is a very important part of those programmes, but you have to be really careful to ensure this isn't a 'one-size-fits-all' approach. Player associations have a common interest with sports bodies to maximise the interest in the sport and commercial viability so the players can share in their wealth, but the impact is dispiriting.

"If we look at the way players are being trained physically, physical loads are being tailored based on the individual athletic capacity of certain players. Physical health is not the only health and safety concern we have to be worried about. Players have different vulnerabilities in terms of mental health and therefore it makes absolute sense for sports bodies to tailor their commitments, so they don't unnecessarily expose more vulnerable players than others. A blanket rule, like in this case, where athletes feel vulnerable and are at risk of an adverse health consequence should not be imposed.

"I really do believe the tournament organisers, Roland Garros in particular, exacerbated that harm when they started to promote the fact that other players were comfortable to do the press conferences in order to put pressure on Naomi, and clearly that has proven to be incredibly counterproductive… if the starting point is not a recognition of their proactive duty to provide a safe workplace and that safe workplace means understanding the physical, mental and the wellbeing risks holistically and then tailoring for the particular needs of players individually, then these kind of problems will likely reoccur."

Stefanos Tsitsipas has been delighted with the backing he has received at the French Open as he continues his quest to better last year's semi-final run.

The 22-year-old has previously spoke of his fondness for Roland Garros, and he earned a tour-leading 35th win of the season against Pedro Martinez on Wednesday.

It finished 6-3 6-4 6-3 in the second round in favour of the fifth seed, who is yet to lose a set at this year's second grand slam.

Tsitsipas is leading the FedEX ATP Race to Turin, and John Isner stands in his way of a fourth-round place.

"I really like playing in Paris," said Tsitsipas, who won titles in Monte Carlo and Lyon before heading to Roland Garros.

"I feel like the fans have embraced me and made me one of them. So, I'm really glad my tennis is there, my performance is there, and I'm able to deliver not just good tennis but also create a good atmosphere on this court."

Tsitsipas, who at one point dropped his racket while serving, did have to work for his win, though. Martinez broke him in the first and second sets, and the Greek was then denied the opportunity to serve out the win in the third.

Martinez's stand did not last much longer – Tsitsipas' backhand winner in the following game sealing the win.

"I've had good weeks this year, I've had some good results, but, of course, I feel like there's always better," the world number five added.

"I don't see my performance so far as super-excellent and outstanding, but I've been consistent and that's very important."

MEDVEDEV BITES BACK

Daniil Medvedev might finally have settled into life at Roland Garros. The second seed had a dismal record in the French Open heading into this year's grand slam, but despite a shaky start on Wednesday, he defeated Tommy Paul 3-6 6-1 6-4 6-3 to claim a place in round three.

Though Paul made the most of a shaky opening set from Medvedev, the Russian rallied in set two and kept the momentum going, winning 80 per cent of his first-serve points in a victory which took two hours and 18 minutes to round off, and also included eight breaks of serve from the world number two.

Next up is Reilly Opelka, who saw off Jaume Munar. The American has a losing 2-1 head-to-head record against Medvedev, though this is the first time they will meet on clay.

There was a shock elsewhere, as 11th seed Roberto Bautista Agut was dumped out by Swiss qualifier Henri Laaksonen.

ZVEREV GETS SNAPPY AFTER RAGGED DISPLAY

World number six Alexander Zverev was made to work for his place in round three, as he overcame Roman Safiullin 7-6 (7-4) 6-3 7-6 (7-1).

Zverev trailed in both the second and third sets, as the 24-year-old needed two tie-breaks to beat the qualifier.

"Obviously, I don't do it on purpose," Zverev said. "I don't go into the match and say, 'Okay, my tactic is I'm going to be a break down, I'm going to fight back and come back'.

"That's not how it works. I'm a break down most of the time because I play unfocused games or the opponent plays well."

Zverev will play Laslo Djere in round three, and despite his frustration after the match, the German has moved onto 20 wins for the season, which already includes titles in Acapulco and Madrid.

Djere beat fellow Serbian Miomir Kecmanovic, and if Zverev should keep winning, he may well face a quarter-final against Casper Ruud, the promising Norwegian player who beat Kamil Majchrzak 6-3 6-2 6-4 to make it to the third round at Roland Garros for a third straight season.

Standing in the way of Ruud and the last eight is Alejandro Davidovich Fokina, who went the distance to defeat Botic Van De Zandschulp.

Serena Williams said her serve was the key to battling past Mihaela Buzarnescu 6-3 5-7 6-1 in the second round of the French Open on Wednesday.

The win improved Williams' second-round record in grand slams to 74-2, her only defeats at this stage having come against sister Venus Williams when Serena made her major debut at the 1998 Australian Open, and against Garbine Muguruza seven years ago at Roland Garros in Paris.

Serena Williams won 75 per cent of the points played behind her first serve and saved five of the seven break points she faced in the French capital midweek.

"I felt it was pretty good today," Williams said of her serve. "But I've been practicing my serve a lot. I've been playing unbelievable on my serve in practice. The other night was, 'wow'. I'm glad it came better today.

"My coach told me it's good that I'm doing it well in practice because eventually it will be good in the match.

"I had some really good chances in the second set to win that. If I would have won just one point here or there, like four or five times, it would have been a different second set.

"I know going into the third I just had zero in on those one important points. If I could just take those, it would be an easier time for me."

The 39-year-old will continue her quest for a fourth Roland Garros title and record-equalling 24th slam crown against compatriot Danielle Collins, who beat Ukrainian qualifier Anhelina Kalinina 6-0 6-2.

"She's been playing well," Williams added. "She's also a really awesome person off the court. I love seeing her in the locker room.

"Ideally, it would be great if we didn't have to play each other because I always want her to do super well."

BENCIC DUMPED OUT BY KASATKINA

Belinda Bencic – the 10th seed – was dumped out by Daria Kasatkina 6-2 6-2, meaning there are no top-20 players left in the bottom quarter of the draw.

Bencic joined world number two Naomi Osaka, Bianca Andreescu and Kiki Bertens in departing the tournament after a dismal performance against Kasatkina, who will play in the third round of a major for the first time since Wimbledon in 2018.

Kasatkina's serve was in rude health, with the Russian and 2018 French Open quarter-finalist never facing a break point and racking up eight aces.

"A lot has changed between 2018 and now," said Kasatkina. "There was one amazing year for me, which was important in a good and in the bad way.

"I learned a lot, and I think I became a little bit different, maybe more experienced, a bit more serious. Let's say I understand more why I'm winning or why I'm losing.

"At that time everything was just going with the wave, and I was not thinking that much. Now I'm analysing more of what's going on in the situation I'm in. Getting maybe a bit more mature."

The only player left in that quarter who has previously reached a grand slam semi-final is 20th seed Marketa Vondrousova, who breezed past Harmony Tan 6-1 6-3. 

SABALENKA SEES OFF COMPATRIOT SASNOVICH

Third seed Aryna Sabalenka booked her spot in the third round with a 7-5 6-3 win over fellow Belarusian Aliaksandra Sasnovich, despite tallying 34 unforced errors.

Sabalenka, who has the second-most tour-level wins this season with 27, said: "I'm really proud of myself that I was fighting no matter what, kind of trying to find my rhythm. I'm really happy with this win. It was a tough battle.

"I would say I definitely feel better this year, kind of believe that I can do well here on the clay court. I feel better and really happy to be here, to compete here."

Sabalenka will now face 31st seed Anastasia Pavlyuchenkova in the next round after the Russian defeated Ajla Tomljanovic 6-2 6-3. 

There were also wins for two-time grand slam champion Victoria Azarenka, who overcame Clara Tauson 7-5 6-4, and Madison Keys, who beat Leylah Annie Fernandez 6-1 7-5.

Serena Williams took the long route through to round three at the French Open as the veteran battled past Romanian Mihaela Buzarnescu.

The American waved the chequered flag at the Monaco Grand Prix 10 days prior to this clash, but there will be no white flag in Paris yet from Williams who dug deep for a 6-3 5-7 6-1 win.

Three times a Roland Garros champion, Williams continued her search for more title-winning form on Court Philippe Chatrier, and a tricky clash with compatriot Danielle Collins will be next for the 39-year-old.

This win improved Williams' second-round record in grand slams to 74-2, her only defeats at this stage having come against sister Venus Williams when Serena made her debut in the majors at the 1998 Australian Open, and against Garbine Muguruza seven years ago at this tournament.

Williams controlled the opening set against Buzarnescu, but the Romanian world number 174 was a wily opponent and began to ask plenty of questions of the 23-time grand slam winner.

Having been as high as number 20 in the rankings, Buzarnescu was not intimidated. In 2018, she beat top-10 players Jelena Ostapenko and Elina Svitolina – twice, in Svitolina's case – and the 33-year-old broke to lead 4-2, with Williams recovering from 0-40 before netting a forehand followed by a backhand as the pressure told.

Williams broke back, yelling "Come on!" to rally herself, and she had two break chances again at 5-5, but could take neither.

Buzarnescu was the first to have a set point and an eye-catching cross-court backhand forced the decider.

Tension briefly filled the air but it soon drifted away, Williams taking command with an immediate break followed by another to lead 4-0, the decider going her way emphatically.

"She has a lot of skills," Williams said of Buzarnescu. "She plays really well on this surface in particular. I knew it wasn't going to be easy, but I'm excited to get through there. It was good competition."

DATA SLAM: LUCKY NUMBER SEVEN?

Williams lives to fight another day and perhaps a good workout will give her the confidence to come through battles that lie ahead. That record-equalling 24th slam remains a possibility this fortnight. Collins is next, a player Williams narrowly beat when they met at the Yarra Valley Classic in Melbourne earlier this year, their one previous meeting. Serena has won two of her previous grand slams as the seventh seed before – at the 1999 US Open and the 2005 Australian Open.

Men's top seed Novak Djokovic says he empathizes with Naomi Osaka having been on the wrong side of the media in the past following her withdrawal from the 2021 French Open.

Four-time grand slam winner Osaka pulled out of Roland Garros on Monday, a day after tournament organisers said her continued refusal to attend compulsory news conferences could result in her being expelled from the Open.

Osaka had come out publicly prior to the French Open and announced she would not attend the news conferences after matches at Roland Garros, citing mental health reasons.

After winning in the first round, Osaka opted out and explained her decision in a social media statement where she said has had bouts of depression since winning the US Open in 2018 and never intended for her stance to become a distraction.

Djokovic, who came under fire last year for his role in the Adria Tour and his US Open default, was asked about Osaka's situation at his post-match news conferences after his straight sets win over Tennys Sandgren on Tuesday.

"Naomi is very young… I can understand her very well. I can empathise because I was on the wrong edge of the sword in my career many times with media," Djokovic said.

"I know how it feels. I support her. I think she was very brave to do that.

"I'm really sorry that she's going through painful times and suffering mentally. I wish her all the best.

"She's a very important player, brand and person for our sport. We need to have her back.

"This was a very bold decision from her side but she knows how she feels best. If she needs to take time and reflect and recharge, that's what she needed to do. I respect it fully. I hope she'll come back stronger."

Djokovic, who was 18 major titles to his name, added that he understood the stance of the French Open and other Grand Slams who have insisted on news conferences being mandatory after every match.

"The grand slams are protecting themselves and their own business," he said. "Of course, they're going to follow the rules and make sure you are complying otherwise you'll be paying fines and getting sanctioning.

"It's not surprising to me that that was their reaction. We're used to this environment and the principles of us doing interviews after every match and getting to answer questions that are majorly quite similar.

"But it's part of our sport and what we do. The media is important without a doubt. It's allowing us to have the platform to communicate with our fans but in a more traditional way.

"It used to be the only way how we could reach out to our fans. In the last five to 10 years it's not the case anymore. We have our own platforms and social media accounts."

Djokovic won 6-2 6-4 6-2 over Sandgren, compiling 33 winners to extend his outstanding French Open first round record to 17-0.

"I thought I played really well, moved very well," he said. "From the later stages of the Rome tournament until now, I'm finding my groove on the court, striking the ball well."

The leaders of tennis' four grand slam events have commended Naomi Osaka for opening up about her mental health problems and have vowed to put players' wellbeing first.

Osaka pulled out of the French Open on Monday, a day after organisers fined the four-time grand slam winner and threatened her with more severe sanctions for refusing to attend mandatory media conferences.

The world number two said in a statement posted on social media that she has had "long bouts of depression" since winning the US Open in 2018 and never intended for her stance to become a distraction.

Osaka also indicated that she was willing to work closely with tour officials "to discuss ways we can make things better for the players, press and fans."

Amid criticism for the way in which they have handled the matter, those in charge of the French Open, Wimbledon, US Open and Australian Open have now softened their stance.

A joint statement on Tuesday from French tennis federation president Gilles Moretton, All England Club chairman Ian Hewitt, U.S. Tennis Association president Mike McNulty and Tennis Australia president Jayne Hrdlicka read: "On behalf of the Grand Slams, we wish to offer Naomi Osaka our support and assistance in any way possible as she takes time away from the court.

"She is an exceptional athlete and we look forward to her return as soon as she deems appropriate. Mental health is a very challenging issue, which deserves our utmost attention.

"It is both complex and personal, as what affects one individual does not necessarily affect another. 

"We commend Naomi for sharing in her own words the pressures and anxieties she is feeling and we empathise with the unique pressures tennis players may face. 

"While players' wellbeing has always been a priority to the Grand Slams, our intention, together with the WTA, the ATP and the ITF, is to advance mental health and wellbeing through further actions.

"Together as a community we will continue to improve the player experience at our tournaments, including as it relates to media.

"Change should come through the lens of maintaining a fair playing field, regardless of ranking or status. Sport requires rules and regulations to ensure that no player has an unfair advantage over another.

"We intend to work alongside the players, the tours, the media and the broader tennis community to create meaningful improvements. As Grand Slams, we aim to create the stage for the players to achieve the highest accolades in our sport."

Osaka's shock withdrawal generated an outpouring of support across the tennis world and beyond, with the likes of Serena Williams, Billie Jean King and Martina Navratilova backing the 23-year-old's stance.

Gael Monfils also chipped in on Tuesday, the top-ranked French men's player pointing out that it is difficult to judge Osaka's situation from the outside.

"We need Naomi. We need her definitely to be 100 per cent," he said following his win over Albert Ramos-Vinolas.

"We need her back on the court, back on the press conference, and back happy. You know, that's what we need.

"What she's dealing with is tough for me to even judge, because I think she has massive pressure from many things.

"I think she's quite young. She's handling it quite well. Sometimes we want maybe too much from her, and then how she says maybe she can't manage it that well, so sometimes for sure she's going to make some mistakes.

"But I give her always the chance because she's a champion, she's quite young, she has a huge influence. I think she needs to take some time for herself to work on herself, feel better."

Novak Djokovic eased into the second round of the French Open thanks to a straight-sets win over Tennys Sandgren in the final match at Roland Garros on Tuesday.

The top seed – beaten by Rafael Nadal, who is in the same half of the draw, in the Paris final last year – had won his previous 16 first-round contests at the French Open, and there never appeared to be any danger of him failing to extend that record on Court Philippe-Chatrier.

Indeed, this meeting lasted under two hours, with the world number one cruising through 6-2 6-4 6-2 without conceding serve and while hitting 33 winners in the process.

It also brought up his fourth career win over Sandgren, maintaining a 100 per cent record over the world number 66. Pablo Cuevas awaits in round two.

Sandgren was a break down in a hurry as Djokovic breezed through the first set in just 31 minutes.

The 34-year-old – a five-time Roland Garros finalist who claimed his solitary title at the event in 2016 – grew frustrated in the second set as he made nine unforced errors and offered up six break points, yet he saved them all.

It evidently demoralised Sandgren, who had put everything into trying to draw level, and the American swiftly found himself 4-1 and two breaks down in the final set, with Djokovic moving through the gears.

A sloppy shot into the net cost Djokovic his first match-point opportunity at 5-2 up, yet he made no mistake as he served out for the win – Sandgren's overhit cross-court forehand rounding off a one-sided contest.

Data Slam: Super Djokovic serves up a treat

Eighteen-time grand slam champion Djokovic may not have needed to live up to his own lofty standards, but his service game was typically excellent in the evening session. He landed 49 of 73 first serves, helping him to win 86 per cent of his first-serve points (42/49).

Ashleigh Barty acknowledged it will be a "tough" week for her at the French Open as she plans to play through the pain at Roland Garros.

Barty – champion in Paris back in 2019 – had to take a medical time out during her first-round tie with Bernarda Pera on Tuesday.

The Australian world number one struggled with a hip issue, yet still progressed with a 6-4 3-6 6-2 win.

"It's going to be a little bit tough this week. I think over the weekend we had a bit of a flare-up through my left hip, which obviously just needed a bit of help today, needed some assistance to try and release it off as best I could," the 25-year-old said in her post-match news conference.

"I'm not going to hide behind the fact I'm not quite 100 per cent but I can guarantee that I will go out there with the right attitude every day and be really accepting of that and give it a crack no matter what.

"We're confident in that we can get my body to a point where I'm able to compete. We're here, we're fighting, we're in with a chance, and that's all we can do."

Magda Linette is next up for Barty on Thursday, the Polish player defeating Chloe Paquet in straight sets.

COCO CARRIES ON HER FORM AS SEEDS REACH ROUND TWO

Fresh from her triumph in both the singles and doubles in Parma, and a run to the Internazionali BNL d'Italia semi-finals, Coco Gauff started her campaign with a tough win over qualifier Aleksandra Krunic.

Gauff, the 24th seed, certainly had to do it the hard way, with the 17-year-old clawing back four set points in the opener, but some brilliant first serves – she landed 71 per cent of them – got her through in straight sets.

It brought up Gauff's first win at a grand slam as a seed. She is ranked at 25th in the world, making her the youngest American woman to make it into the top 25 since Serena Williams in 1998. 

Wang Qiang will face Gauff in round two in what is a repeat of the Parma final.

Meanwhile, three other big names also made it through. Former world number one and 2017 French Open semi-finalist Karolina Pliskova overcame her close friend Donna Vekic 7-5 6-4, while fellow Czech Karolina Muchova came from behind to beat Andrea Petkovic 1-6 6-3 6-4.

With Petkovic's exit, there are no female players from Germany in the second round at Roland Garros for the first time since 1958.

Fifth seed Elina Svitolina is also through to round two after coming back from a break down in the second set to beat teenager Oceane Babel 6-2 7-5.

"It's a first time for her to play here in the main draw of the grand slam and to face the sixth player in the world it's extremely tough," Svitolina said of her young opponent.

"I think she dealt very well with it and she went for her shots in the second set and made life very difficult for me."

SUAREZ NAVARRO MAKES COMEBACK

Carla Suarez Navarro overcame Hodgkin lymphoma earlier this year, after revealing last September that she had been diagnosed with the rare cancer.

Suarez Navarro won that battle and is now cancer free, but in what she said will be her last appearance at Roland Garros, she slipped to a defeat to 2018 finalist Sloane Stephens.

The Spaniard took the first set 6-3 and forced a tiebreaker in the second, but it was Stephens who edged it before taking that momentum into the decider to claim a 3-6 7-6 (7-4) 6-4 win.

Rafael Nadal has tipped Alexei Popyrin for greatness after being tested by the youngster in the opening match of his latest French Open title defence.

World number three Nadal saved two set points in the third set on his way to a well-earned 6-3 6-2 7-6 (7-3) victory in Tuesday's contest at Roland Garros.

It means that only three players have taken a set from the Spaniard at the grand slam event since 2016 – Diego Schwartzman, David Goffin and Dominic Thiem.

Nadal's victory over Popyrin was his 31st in a row in Paris since 2015 and keeps him on course for a record-extending 14th triumph in the French capital.

The third seed was impressed by what he saw from his 21-year-old opponent, who showed admirable resistance by saving four break points to force a tie-break in the third set.

"With this serve, with these kinds of shots from the baseline, he has everything to become a top player," Nadal said. "If he wants to do it, of course he is going to have his chances, because he has a lot of very difficult things in his game.

"He has everything to become a great, or at least a fantastic player. Let's see. Let's see what is going on in the next couple of months and years."

Asked about his impressive record of rarely dropping a set, Nadal said: "We are playing best-of-five. The other player needs to win two more sets to beat you.

"I know I'm going to be there fighting for every single point. Of course I don't want to lose the set at all, but that's part of the game.

"I'm happy to win that third set. I don't know how I won it, but I did, and I'm glad."

RUBLEV BEATEN BY BIG-SERVING STRUFF

Nadal's path to another French Open title is a little clearer following seventh seed Andrey Rublev's surprise first-round exit to world number 42 Jan-Lennard Struff.

Rublev had reached the quarter-final stage at his previous three majors and was much fancied to go far in Paris, but he fell 6-3 7-6 (8-6) 4-6 3-6 6-4 to the big-serving Struff.

The German hit 25 aces on his way to beating a top-10 opponent at a grand slam for the first time, setting up a second-round meeting with Facundo Bagnis.

"I was feeling fine," Rublev said after the defeat. "I practiced well. I don't know why I lost. I think we played a good level today. I played a solid two sets, third and fourth, and then the fifth set.

"I think I should have won the second set, but this is tennis. I was serving for the set and I didn't make it, then in the tie-break I was a bit unlucky and he played well."

MONFILS ENDS SLAM DROUGHT

Fan favourite Gael Monfils battled back from a set down to beat Albert Ramos-Vinolas 1-6 7-6 (8-6) 6-4 6-4 and earn his first grand slam win since the 2020 Australian Open.

Monfils has struggled since tennis resumed last year after the coronavirus-enforced break, with Tuesday's win on home soil just his second this season.

Elsewhere on Tuesday, Australian Open semi-finalist Aslan Karatsev kicked off his French Open campaign with victory over Jenson Brooksby in three sets.

Tenth seed Schwartzman, who reached the last four in Paris last year, saw off Lu Yen-hsun 6-2 6-2 6-3 in his opening match.

Matteo Berrettini was made to work a little harder for his victory against Taro Daniel, the ninth seed advancing through 6-0 6-4 4-6 6-4.

There was an upset later in the day, though, as number 20 seed Felix Auger Aliassime was beaten in four sets by world number 98 Andreas Seppi.

Rafael Nadal started his quest for a 14th French Open title with a straight-sets defeat of Alexei Popyrin on Tuesday.

The defending champion will face Richard Gasquet in the second round after a 6-3 6-2 7-6 (7-3) victory over powerful Australian Popyrin on Court Philippe-Chatrier.

Nadal, eyeing a record 21st grand slam title, saved two set points in the third set as Popyrin gave a demonstration of his promise, but the world number three finished off the job in in two hours and 23 minutes on a glorious day in Paris.

Popyrin held to love in his first service game and matched Nadal in the first set before he ballooned a forehand long and wide to go 5-3 down.

Nadal served out the set in typically composed fashion and maintained his momentum in the second, charging into a 4-0 lead.

The third seed lost only three points behind his first serve in the second set, saving the only break point he faced as Popyrin was unable to live with his power and precision.

Popyrin would not go down without a fight, though, and although Nadal levelled at 2-2 after fending off a break point, he was unable to deny the world number 63 a first break for a 4-2 lead.

The 21-year-old failed to win two set points when he tried to serve it out at 5-4 up as Nadal got himself out of trouble and went on to dominate the tie-break, ending the match with a rasping forehand that his opponent returned well wide.

Petra Kvitova has withdrawn from the French Open after damaging her ankle in a fall during a press conference on Sunday.

Kvitova was due to face Elena Vesnina in the second round at Roland Garros, having already beaten qualifier Greet Minnen in straight sets.

The 11th seed's participation in the second grand slam of the year is over, though, due to a freak injury suffered as she was carrying out media duties after her opening match.

Kvitova - a two-time Wimbledon champion - is hoping to recover in time for the grass-court season following such an unfortunate setback.

"It is with great disappointment that I announce my withdrawal from Roland Garros," she tweeted on Tuesday.

"During my post-match press conference on Sunday I fell and hurt my ankle. Unfortunately, after an MRI and much discussion with my team, I have made the tough decision that it would be unwise to play on it.

"It's incredibly bad luck, but I will stay strong and do my best to recover for the grass court season."

World number one Ash Barty battled through injury and a stubborn opponent in Bernarda Pera on Tuesday to advance to round two of the French open in three sets.

Barty, who missed out on the chance of defending her title at Roland Garros last year due to coronavirus restrictions, struggled with a back issue but still prevailed 6-4 3-6 6-2.

The top seed had 18 winners to 25 unforced errors as she made it eight wins in Paris, where either Magda Linette or Chloe Paquet await in the next round.

She had little trouble in seeing out the first set, hitting 80 per cent of her first serves, but she became passive from that point on and her opponent took advantage in the second set.

World number 70 Pera earned the only break in the second game and took her second set point to level up the contest.

Barty then had a scare as she called a medical time out at the beginning of the deciding set, but she looked a lot more focused from that point on.

The Australian saved the two break points she faced and broke Pera in the sixth and eighth games to pick up the victory in exactly two hours.

"This court is very close to my heart," Barty said in her on-court interview. "It's so nice to play here in front of fans, you make it enjoyable for players. 

"Thank you very much. I just keep fighting. I was able to build more pressure in the third set which was important but Bernarda played an incredible match."

Boris Becker fears Naomi Osaka's career could be "in danger" after she withdrew from the French Open to prioritise improving her mental health.

Osaka had hit the headlines by revealing she would not face the media at Roland Garros because "people have no regard for athletes' mental health" during news conferences.

The four-time grand slam champion was fined for not fulfilling her media duties after beating Maria Tig and warned she could face more severe sanctions.

Osaka on Monday revealed she had pulled out of the second major of the year to take time away from the court, having struggled with "long bouts of depression" since winning the US Open in 2018.

The 23-year-old also spoke of her struggles with social anxiety and Becker is concerned for her tennis future.

Becker, a winner of six grand slam titles in his illustrious career, told Eurosport: "I heard her first response a couple of days ago about this media boycott and that is something to be always taken seriously, especially from such a young woman.

"She couldn't cope with the pressures of facing the media after she loses a match, but that happens frequently and you have to deal with it.

"I always believed the media was part of the job. Without the media, there is no prize money, no contracts, you don't get half the cake. I hated the media and I didn't like talking to journalists, but you had to do it.

"Now she is pulling out of the tournament altogether because she can't cope with it and that raises much bigger questions for me.

"If she can't cope with the media in Paris, she can't cope with the media in Wimbledon or the US Open. So I almost feel like her career is in danger due to mental health issues."

Naomi Osaka's shock withdrawal from the French Open generated an outpouring of support across the tennis world and beyond. 

The four-time grand slam winner pulled out of Roland Garros on Monday, a day after tournament organisers said her continued refusal to attend mandatory press conferences could result in her being thrown out of the event.

Osaka said in a statement posted to social media that she has had bouts of depression since winning the US Open in 2018 and never intended for her stance to become a distraction. 

Monday's action in Paris had mostly been completed when the news broke, but Serena Williams shared her thoughts following an evening match. 

Williams acknowledged feeling anxious dealing with the press at times early in her career, but said she believed the experience made her stronger. 

Top of mind, however, was concern for Osaka. 

"The only thing I feel is that I feel for Naomi. I feel like I wish I could give her a hug because I know what it's like," Williams said.

"We have different personalities, and people are different. Not everyone is the same. Everyone is different and everyone handles things differently.

"You just have to let her handle it the way she wants to, in the best way she thinks she can, and that's the only thing I can say. I think she's doing the best that she can."

Osaka's fellow players and others took to social media with encouraging messages for the 23-year-old. 

Venus Williams wrote on Instagram: "So proud of you. Take care of yourself and see you back winning soon!"

Young American star Coco Gauff responded to Osaka's tweet by writing "stay strong ... I admire your vulnerability." 

A pair of tennis legends also weighed in on Twitter. 

"I am so sad about Naomi Osaka. I truly hope she will be ok," Martina Navratilova wrote.

"As athletes we are taught to take care of our body, and perhaps the mental and emotional aspect gets short shrift.

"This is about more than doing or not doing a press conference. Good luck Naomi - we are all pulling for you!"

Billie Jean King added: "It’s incredibly brave that Naomi Osaka has revealed her truth about her struggle with depression. Right now, the important thing is that we give her the space and time she needs. We wish her well."

Mardy Fish, the former ATP player who reached number seven in the world, wrote to Osaka: "Mental health is nothing to criticise. Nothing to joke about. Pls [sic] take your mental health seriously. Without my support system, I truly believe I would not be here today. Here for you."

That public show of support extended beyond tennis, as prominent NFL and NBA players praised Osaka for her courage. 

"We are with you," said Seattle Seahawks quarterback Russell Wilson.

NBA star Stephen Curry wrote: "You shouldn't ever have to make a decison like this - but so damn impressive taking the high road when the powers that be don't protect their own. Major respect."

Serena Williams started her quest to match Margaret Court's grand slam record by seeing off Irina-Camelia Begu in the first round of the French Open.

Williams, who reached the semi-finals in Melbourne earlier this year, has been stuck on 23 slam triumphs – one shy of Court's career haul – since winning the 2017 Australian Open.

But the seventh seed in Paris did just enough in a challenging opening outing on Monday, the first official night match in French Open history, overcoming Begu 7-6 (8-6) 6-2 in one hour and 44 minutes.

Begu proved a worthy match, winning four straight games and at one point holding two set points in the opener, but the world number eight's quality and experience ultimately came to the fore.

Having charged into a 5-3 lead, Williams found herself at 0-30 down when serving for the first set, and an overhit slice followed by another errant, awkward backhand gave Begu the break.

More unforced errors followed from Williams as her hopes of clinching the set with a return break were dashed, before the 39-year-old scooped long on her own serve to give Begu the advantage.

The American regained her composure to hit back, though, and force a tiebreak. Begu had two set points to play with at 6-4 up, but Williams rallied, winning the next four to take a hard-fought lead.

A superb drop shot teed Williams up for a break at the start of the second set, yet she tensed up again in game six.

Williams was applauding Begu for a supreme forehand down the line, but the former world number one was soon frustrated as the Romanian clawed back to deuce three times.

Begu's resolve finally crumbled, however, and Williams was left to serve out a win which sets up a second-round tie with Mihaela Buzarnescu.

DATA SLAM: Error-strewn Williams will have to sharpen up

By 3-3 in the tiebreaker, Williams had made 21 unforced errors, in contrast to just seven from Begu. Williams tightened up after nosing ahead, making just nine more in the remainder of the contest, but she will know such issues cannot continue if there is to be a chance of reigning again in the French capital this year.
