Naomi Osaka has been handed a difficult first round draw against 2017 US Open winner Sloane Stephens upon her return to the WTA Tour at Indian Wells which starts on Wednesday.

Four-time major winner Osaka has not played competitively since her 2022 Australian Open third-round exit to Amanda Anisimova in January.

The Japanese, whose ranking has dropped to 78th, had been handed a wild card for Indian Wells but was upgraded to the main draw after Camila Giorgi's withdrawal.

The Indian Wells draw was made on Monday with Osaka to face Stephens who won her first WTA title since 2018 with last month's Abierto Zapopan crown.

The top seeds all have been waived through to the second round with top seeds Barbora Krejcikova and Aryna Sabalenka book-ending the draw.

Leylah Fernandez saved five championship points before converting her first to successfully defend her title at the Monterrey Open over Camila Osorio on Sunday.

Last year's US Open runner-up Fernandez triumphed in two hours and 52 minutes over the Colombian fourth seed winning 6-7 (5-7) 6-4 7-6 (7-3).

The Canadian second seed held her nerve after a 15-minute delay due to a light failure inside the stadium upon Osorio's fifth championship point. Fernandez won the next three points upon the resumption to force a tiebreak which she won.

The triumph is 19-year-old Fernandez's second WTA title, both in Monterrey, having lost the Mexican Open final in 2020 as well as at Flushing Meadows to Emma Raducanu last year.

Osorio, 20, was chasing her second WTA title but will be left to rue missed opportunities, converting only four of her 15 break points for the match.

The reigning champion had led 4-1 in the opening set before Osorio fought back to win the set in a tie-break.

Fernandez again led 4-1 in the second set before Osorio responded with a break, but the Canadian steadied to level the match.

Osorio broke Fernandez in the fourth game of the final set and also led 4-1 before the popular 19-year-old leveled at 4-4.

The Colombian failed to convert her first championship point on Fernandez's serve at 40-30 when up 5-4, as well as four more opportunities on the Canadian's serve at 6-5. Fernandez was ruthless in the tie-break, swooping on her first championship point.

Zhang Shuai secured her third career title as she battled past Dayana Yastremska in a Lyon Open final thriller on Sunday.

Ukrainian Yastremska fled her hometown of Odessa last month amid the ongoing conflict between Ukraine and Russia, and embarked on an emotional run throughout this tournament.

Yastremska credited the support she received from across the globe as a motivating factor for her success after reaching the final, where she could not get the better of eighth seed Zhang.

China's Zhang had not lost a set all week, though she did falter as world number 128 Yastremska claimed the first set before succumbing 3-6 6-3 6-4.

Yastremska, 21, was twice two games ahead in the deciding set, at 2-0 and 4-2 up, but Zhang reeled off four straight games to take the trophy.

Zhang was keen to credit her opponent after the match, saying: "Big congrats to Dayana and her team for working so hard.

"I know it's a tough time for you, but you are a fighter, you play unbelievable tennis. You are the best. For sure, you will win a lot of tournaments. Keep going."

Yastremska announced she would donate her prize money to a charity to provide aid back home, saying: "If Ukrainian people are watching me, you guys are so strong, you have an amazing spirit.

"I try to fight for Ukraine and I want to say thanks to every single person for standing by us and showing everyone we have a really strong spirit."

Leylah Fernandez's title defence at the Monterrey Open remains on track after progressing through to the final where she will face Camila Osorio.

The Canadian second seed, who reached last year's US Open final, comfortably accounted for Brazilian Beatriz Haddad Maia 6-1 6-4 on Saturday.

Fernandez triumphed in one hour and 12 minutes, even as Haddad Maia took a medical timeout in the second set.

The 2021 US Open runner-up was exceptional on first serve, making 77.6 per cent, while she was not broken once throughout the match, taking three of her four break points.

Colombian fifth seed Osorio defeated sixth seed Nuria Parrizas Diaz 6-4 6-4 in one hour and 29 minutes.

Osorio's triumph means she qualifier for her third WTA Tour singles final, having claimed her only title in Bogota last year.

Dayana Yastremska says she did not expect the support she has received on her run to the final of the Lyon Open after edging second seed Sorana Cirstea in a three-set semi-final thriller.

The Ukrainian was forced to flee her home in Odessa last month amid the escalation of the Ukraine-Russia crisis and has embarked on an emotional run through this week's tournament.

Yet the 21-year-old wildcard admitted she has been overwhelmed by the support from across the globe amid her winning streak, crediting them for their help in her 7-6 (7-5) 4-6 6-4 victory on Saturday.

"It was a really tough match," Yastremska said. "In the third set, when I had match points and I lost that game, I was a bit crazy. I thought, I'm done, I've lost, because I don't have any more power.

"Then everybody was supporting me, and I felt like, 'you can do it'. I got a lot of messages from French people and from all over the world. But when I arrived here, I didn't expect I would get that huge support."

Yastremska will face Zhang Shuai in Sunday's final, after the Chinese eighth seed defeated French home favourite Caroline Garcia 6-2 7-5.

For Yastremska, it will be her first final since losing to Ash Barty in Adelaide at the start of 2020 – her only previous tournament success came in Strasbourg the year before.

Elina Svitolina saw her hopes of delivering an emotional title for Ukraine ended by Camila Osorio in a tough quarter-final loss at the Monterrey Open.

Top seed Svitolina wore the yellow and blue colours of her home country, which has come under attack from Russia's military in the past fortnight.

However, the former world number three could not capitalise on a fast start, or a big lead in the deciding set, as she slipped to a 1-6 7-5 7-6 (7-5) defeat in two hours and 33 minutes.

Svitolina held a 4-1 lead in the third set, but 20-year-old Colombian Osorio recovered the double break to edge out the 2020 champion, sealing the win in a deciding tie-break.

That was the third tight three-set battle of the day, with Brazil's Beatriz Haddad Maia earlier scoring a 4-6 6-4 7-6 (9-7) win over Marie Bouzkova, and Nuria Parrizas Diaz achieving a 6-3 1-6 6-4 victory in an all-Spanish clash with Sara Sorribes Tormo.

Parrizas Dias will face Osorio in Saturday's semi-finals, while Haddad Maia faces a tussle with US Open runner-up Leylah Fernandez, who was a late-night 7-6 (7-4) 6-4 winner against China's Wang Qiang.

Dayana Yastremska maintained her emotional run at the Lyon Open by beating fifth seed Jasmine Paolini in straight sets to book a semi-final spot. 

The Ukrainian wildcard secured her place in the last four on Friday with a 6-4 7-6 (7-3) victory over the Italian amid the war with Russia in her home country. 

The 21-year-old fled Odessa with her sister last week, separating from her parents in the process, and has spoken about her desire to honour those back in Ukraine with a title. 

She will face second seed Sorana Cirstea after the Romanian made short work of Anna Bondar with a 6-3 6-3 victory. 

Elsewhere, Caroline Garcia toppled another seed after fighting back to beat Alison van Uytvanck 4-6 6-3 7-5. The home favourite knocked out top seed Camila Giorgi in the first round and has a semi-final clash against Zhang Shuai to look forward to. 

Zhang did not have to sweat to make her place after Vitalia Diatchenko was forced to retire at three games down in the first set through injury. 

Ukrainian top seed Elina Svitolina was made to work hard but triumphed in more than two hours against Viktoriya Tomova as she booked her Monterrey Open quarter-final spot on Thursday.

Svitolina won 7-6 (7-3) 3-6 6-2 over the Bulgarian qualifier in two hours and 24 minutes, having trailed 2-0 in the final set, before rattling off the final six games to set up a last-eight meeting with fifth seed Camila Osorio.

The Ukrainian won the title at Monterrey in 2020, with her victory on Thursday maintaining her unbeaten record at the event.

"It was an extremely tough match today," Svitolina said during her on-court post-match interview. "I think Viktoriya played a really good match, and I had to really fight back in the third set to bring back my best game and try to come back in the match.

"In the end, I managed to win six games in a row, so it's a good effort for me. It was an extremely tough first set, second set didn't go my way, and then the third set I was 0-2 down. I was not playing my best, but I was fighting, until the very end.

"And you know, the Ukrainian flag [in the crowd] really helped me today to fight... I was really fighting until the end, and I found my game in the end."

Last week's beaten WTA Abierto Zapopan finalist Marie Bouzkova maintained her good form with a 6-4 6-2 victory over Petra Martic.

Sixth seed Nuria Parrizas-Diaz won 6-4 7-6 (7-2) over Briton Heather Watson, while Wang Qiang defeated Mayar Sherif 6-0 6-7 (2-7) 6-3.

Dayana Yastremska delivered a polished performance as the Ukrainian kept her "very emotional" run going at the Lyon Open.

The 21-year-old broke serve five times on her way to a 6-2 6-3 victory over Spain's Cristina Bucsa in an hour and five minutes, booking a quarter-final place.

Yastremska fled war-ravaged Ukraine last week, along with sister Ivanna, escaping through Romania but leaving their parents behind in Odessa after Russia's invasion began.

The three-time WTA tournament winner has spoken of the decision by her mother to stay with her father, and how that left the sisters tearful and agonising over when the family might be reunited.

Yastremska began her campaign in Lyon with a gruelling three-set win over Ana Bogdan and followed up impressively by sweeping aside Bucsa.

"Today, definitely it was a little bit easier. With my emotions, I could keep them under control, so I'm very happy with that," Yastremska said in an on-court interview, broadcast on Amazon Prime.

"I tried yesterday to recover myself as fast as possible to prepare for my match today. Still, I was very nervous because I wanted to win the match for my country.

"This tournament is very emotional for me, but I'm very happy with the win today. To be honest I'm very happy that I'm here, that I'm in a safe place with my sister."

The former world number 21, now down at 140 in the WTA rankings, was joined in the last eight by Zhang Shuai of China and France's Caroline Garcia.

Also going through to the quarter-finals on Thursday was Vitalia Diatchenko, a Russian playing under a neutral flag this week. She beat Swiss third seed Viktorija Golubic in three sets.

Leylah Fernandez reached the quarter-finals of the Monterrey Open with a battling three-set win over Qinwen Zheng.

Last year's US Open runner-up came through 6-1 4-6 7-6 (7-3) in two hours and 42 minutes to continue the defence of the title she won last March.

Fernandez won a marathon second game on her eighth break point and consolidated that break with a second to go 5-1 ahead in a one-sided first set.

She served out the opener at the third time of asking, but Zheng was beginning to find her feet in the contest and threatened the Fernandez serve early in the second set.

Zheng's first break points finally came at 5-4 and she took her chance to level the contest against the 19-year-old.

But Fernandez outlasted Zheng in a tense decider that went the distance after both players held serve, the second seed aggressively attacking her opponent to take the tie-break 7-3.

Fifth seed Camila Osorio ended the challenge of home hope Marcela Zacarias, meanwhile, the Colombian winning 7-6 (7-3) 6-3.

She will next face either top seed Elina Svitolina or Viktoriya Tomova in the last eight.

Brazil's Beatriz Haddad Maia was a 6-2 6-2 winner against Xinyu Wang and will contest a quarter-final against either Marie Bouzkova or Petra Martic.

Sara Sorribes Tormo was also a straight-sets winner in Wednesday's action, the fourth seed easing past Harmony Tan 6-2 6-2. 

Viktorija Golubic came from a set down to beat lucky loser Mai Hontama and move into the second round of the Lyon Open on Wednesday.

Third seed Golubic was given the run-around by Hontama in the first set before fighting back to win 1-6 6-4 6-4.

Golubic had to dig deep to secure a meeting with Vitalia Diatchenko, who beat Anna-Lena Friedsam, as Hontama's deft drop shots had given her a scent of pulling off an upset.

The Swiss broke six times and saved six break points, wrapping up a well-earned victory in two hours and 10 minutes.

Golubic's compatriot Stefanie Voegele bowed out at the second-round stage, losing 6-3 7-5 to second seed Sorana Cirstea.

Anna Bondar reached the quarter-finals when Katie Boulter retired due to injury after losing the first set 6-3.

Alison Van Uytvanck won the final match of the day, getting the better of Varvara Gracheva 6-2 6-4 to advance to the last eight.

Elina Svitolina said she "was on a mission" for Ukraine after earning a straight-sets win over Russian opponent Anastasia Potapova in the opening round of the Monterrey Open.

The top seed donned the yellow and blue colours of her homeland for Tuesday's match and eased to a 6-2 6-1 victory in a little over an hour in Mexico.

Svitolina only agreed to play her opener after tennis authorities announced a ban on Russian and Belarussian players competing under the name and flags of their countries.

And as Russia's invasion of Ukraine entered its sixth day, the 27-year-old produced an impressive performance that saw her win 73.5 per cent of her first-serve points.

Former world number three Svitolina, who will now face Bulgarian qualifier Viktoriya Tomova, had previously announced she will donate her prize money to the Ukrainian army.

"It's a special one because of what we are going through right now in Ukraine, it's terrifying," Svitolina told reporters. 

"It's been six days and all the Ukrainian tennis players and Ukrainians who are there, we have been really terrified with what is happening.

"For me, playing the match here, I'm not playing only for myself. I'm playing for my country, I'm playing for the help of the Ukrainian army and people in need. 

"I was focused. I was on a mission for my country. From the beginning, it was important to be ready for anything that comes my way."

Petra Martic is also through to round two after recovering from behind to beat third seed Madison Keys 4-6 7-6 (7-3) 6-3.

Marie Bouzkova awaits following the world number 81's 4-6 6-2 6-4 win against Sara Errani. Number eight seed Ann Li's participation in the tournament came to an end with a 6-2 6-1 loss to Wang Xinyu, who will now face Brazil's Beatriz Haddad Maia.

Russian and Belarusian players, including ATP world number one Daniil Medvedev, will still be able to compete on the Tours and at grand slams, but the International Tennis Federation (ITF) has suspended the countries' teams.

Russia's Medvedev was only crowned world number one for the first time on Monday, though that success came amid the backdrop of an ongoing conflict between his nation and Ukraine.

To widespread international condemnation, Russia invaded Ukraine on Thursday, with that conflict since escalating further. Belarus, meanwhile, was effectively used as a staging post for part of the invasion force, though Belarusian president Alexander Lukashenko has insisted the nation's military did not and will not play any part in any operation.

Governments and organisations around the world, including governing bodies within sport, have responded with strict sanctions against Russia and certain individuals with links to president Vladimir Putin.

On Tuesday, the governing bodies of tennis (the ITF, ATP, WTA and the four grand slam events) announced sanctions of their own.

While Medvedev and other Russian and Belarusian players, including Andrey Rublev and WTA world number three Aryna Sabalenka, will be allowed to play in tournaments on both the men's and women's Tours, and the four grand slams, they will have to compete under neutral banners, with the flags of each country banned.

However, the WTA and ATP combined event in Moscow, scheduled to take place in October, has been suspended.

Meanwhile, Russia and Belarus have had their memberships of the ITF revoked, while all ITF tournaments set to be held in those countries have been suspended indefinitely.

Russia hold both the Davis Cup and Billie Jean King Cup.

The immediate upshot of the decision is that Elina Svitolina, the Ukrainian who is top seed at the Monterrey Open, will play her first-round match against Anastasia Potapova on Monday.

Svitolina said earlier in the day that she would refuse to play against any Russian or Belarusian opponent unless all national emblems, flags and colours were removed.

However, prior to the joint announcement from tennis' governing bodies, Svitolina told ITV News: "There's been a lot of discussion.

"Today they will release a statement that they will remove the flags. So we are waiting just for the final confirmation about that. I will be playing tonight because my opponent is going to be under a neutral flag."

Svitolina has pledged to donate all of her prize money from upcoming tournaments to assist Ukraine's fight against Russia.

The statement from tennis' governing bodies read: "A deep sense of distress, shock and sadness has been felt across the entire tennis community following Russia's invasion of Ukraine in the past week.

"Our thoughts are with the people of Ukraine, and we commend the many tennis players who have spoken out and taken action against this unacceptable act of aggression. We echo their calls for the violence to end and peace to return.

"The safety of the tennis community is our most immediate collective priority. The focus of the WTA and ATP in particular in recent days has been on contacting current and former players, and other members of the tennis community from Ukraine and neighbouring countries, to check on their safety and offer any assistance."

Top seed Camila Giorgi was beaten in three sets by Caroline Garcia at the Lyon Open on Tuesday.

Italian Giorgi battled to take the first set but was pegged back by the home favourite before her game collapsed in a 5-7 6-4 6-0 defeat.

Dominant on serve in the opening set, Giorgi failed to take either of two break points at 3-2 up in the second set. She then won only one point in three consecutive games to allow Garcia to level.

The world number 29 earned just two points on serve in a one-sided decider as Garcia set up a last-16 clash with another Italian, Martina Trevisan.

Earlier, Russian Vera Zvonareva was comfortably beaten by seventh seed Alison van Uytvanck, who could await Garcia in the quarter-finals.

Zhang Shuai beat Kristina Mladenovic 7-6 (7-3) 7-5 to secure a match with Arantxa Rus, who defeated Danka Kovinic for the loss of just two games.

The top-ranked remaining player in the draw, world number 30 Sorana Cirstea, sealed a round-of-16 showdown with Stefanie Voegele after a comfortable 6-3 6-1 defeat of Mariam Bolkvadze.

US Open runner-up Leyla Fernandez cruised into the second round of the Monterrey Open after a straight-sets win over Anna Karolina Schmiedlova on Monday.

Monterrey Open defending champion Fernandez won 6-2 6-2 over the Slovakian, with the Canadian second seed dominant in all aspects as she triumphed in one hour and eight minutes.

In the longest match of the day, fourth seed Sara Sorribes Tormo needed more than three hours to edge Kamilla Rakhimova 7-5 6-7 (2-7) 6-1.

Fifth seed Camila Osorio defeated Magdalena Frech 6-3 7-6 (8-6), while Briton Heather Watson won 6-3 2-6 7-6 (7-4) over Jule Niemeier.

Harmony Tan, Marcela Zacarias, Viktoriya Tomova and Beatriz Haddad Maia were other winners on Monday.
