Coco Gauff marched into ASB Classic final with an emphatic defeat of Danka Kovinic, while Linda Noskova upset Ons Jabeur to set up an Adelaide International showdown with Aryna Sabalenka.

Gauff beat Kovinic 6-0 6-2 to move into her first hard-court final since claiming the title in Linz back in October 2019.

The top seed from the United States won the first eight games of a one-sided semi-final, making another statement just over a week before the Australian Open gets under way.

Gauff took only 73 minutes to dispatch seventh seed Kovinic and will face qualifier Rebeka Masarova in the final on Sunday.

Spaniard Masarova reached her first WTA Tour final courtesy of a 6-3 6-3 victory over Ysaline Bonaventure.

The 130-ranked Masarova, a junior French Open singles champion in 2016, served with assurance and struck 16 winners to break new ground.

It was also a memorable Saturday for Czech teenager Noskova, who claimed the scalp of world number two Jabeur with a 6-3 1-6 6-3 victory in Adelaide.

It was the 18-year-old Noskova's second win over a top-10 opponent this week, having also knocked out Daria Kasatkina.

Second seed Sabalenka will be a strong favourite to deny world number 102 Noskova the title on Sunday after she saw off Irina-Camelia Begu 6-3 6-2.

Teenage Czech qualifier Linda Noskova upset former world number one Victoria Azarenka to set up a semi-final showdown with Ons Jabeur at the Adelaide International.

In a match lasting almost three hours, Noskova triumphed 6-4 6-7 (3-7) 7-6 (8-6) to continue a dream run in Australia.

Noskova has already beaten third seed Daria Kasatkina in Adelaide and, on only her sixth appearance in a WTA main draw, has won five straight matches.

Further progress will be no easy feat, with top seed Jabeur – a losing finalist at Wimbledon and the US Open in 2022 – grinding out a 7-6 (7-5) 7-5 win over Ukrainian Marta Kostyuk.

On the other side of the draw, second seed Aryna Sabalenka held off a resurgent Marketa Vondrousova to win 6-3 7-5. The Belarusian had led 4-1 in the second set before losing four of the next five games and failing on match point prior to finally seeing it out.

Irina-Camelia Begu defeated fourth seed Veronika Kudermetova 7-5 6-4 to set up a last-four clash with Sabalenka.

At the ASB Classic in Auckland, top seed Coco Gauff outclassed Zhu Lin 6-3 6-2, winning 90 per cent of first-serve points, firing down eight aces, and not giving up a single break point.

Seventh seed Danka Kovinic also won 6-3 6-2 against Viktoria Kuzmova to set up a semi-final clash with Gauff, while world number 95 Ysaline Bonaventure ousted third seed Leylah Fernandez 6-4 6-2 to reach a first Tour-level semi-final where Rebeka Masarova awaits.

Emma Raducanu was in tears as she retired with an ankle injury at the ASB Classic 11 days before the Australian Open starts, while Coco Gauff beat Sofia Kenin to reach the quarter-finals.

Raducanu dished out a bagel to qualifier Viktoria Kuzmova in the first set of the round of 16 match in Auckland on Thursday, but the 2021 US Open champion was unable to continue after losing the second set 7-5.

The 20-year-old Brit ended a disappointing 2022 season early due to a wrist injury and suffered another blow ahead of the first major of this year, leaving the court in tears.

Gauff will be eyeing her maiden grand slam title in 2023 and she impressively dispatched fellow American Kenin 6-4 6-4 in the second round in the capital of New Zealand.

Top seed Gauff and her compatriot were forced to play indoors due to the rain and it was the 18-year-old who prevailed, breaking three times and saving six of the break points she faced.

The teenager will face Zhu Lin of China for a place in the semi-finals after she beat Venus Williams 3-6 6-2 7-5.

Leylah Fernandez inflicted a crushing 6-0 6-1 defeat on Julia Grabher after losing only two games in her first-round win over Brenda Fruhvirtova and the Canadian will now face Ysaline Bonaventure, who defeated Rebecca Marino in three sets.

Top seed Ons Jabeur made a winning start to the season at the Adelaide International, seeing off Sorana Cirstea 7-6 (7-3) 6-1 to set up a meeting with Marta Kostyuk

Irina-Camelia Begu claimed the scalp of Jelena Ostapenko with a 6-3 6-0 upset of the seventh seed, while Victoria Azarenka was a 6-2 7-5 winner against Zheng Qinwen and teenager Linda Noskova got past Claire Liu in straight sets.

Aryna Sabalenka secured a straight-sets win in her first match of 2023, but was made to work for it by Liudmila Samsonova at the Adelaide International.

The number two seed won 7-6 (10-8) 7-6 (7-3), saving seven set points after going 5-1 down in the first set, before roaring back to take both tie-breaks.

Sabalenka will face Marketa Vondrousova in the quarter-finals, with the Czech having produced a dominant performance in a 6-0 6-4 win against Kaia Kanepi. 

"When it's 1-5 down, it's like you have nothing to lose, and you just go for your shots without thinking," Sabalenka said.

"That really helped me to stay in the set, to keep fighting and to keep trying."

Fourth seed Veronika Kudermetova eased through after a 6-4 6-0 victory against Bianca Andreescu, while Marta Kostyuk also advanced with a hard-fought 6-7 (5-7) 6-2 6-3 win over Elena Rybakina.

At the ASB Classic in Auckland, second seed Sloane Stephens is out after falling to Rebeka Masarova.

Having been forced to resume on Wednesday after rain suspended play the previous day, Stephens struggled against her Spanish opponent, eventually losing 6-3 7-6 (7-5).

Fifth seed Wang Xiyu is also out after retiring from her match against Karolina Muchova, but seventh seed Danka Kovinic is through after a simple 6-1 6-4 win against Nao Hibino.

Kovinic will face Lauren Davis next after she overcame Tamara Zidansek 6-2 6-1, while fellow American Sofia Kenin will take on number one seed Coco Gauff in the last 16 after she beat Wang Xinyu in straight sets.

Emma Raducanu and Coco Gauff both got off to winning starts at the ASB Classic in Auckland on Tuesday.

Raducanu had to come from a set down to beat Linda Fruhvirtova 4-6 6-4 6-2, while top seed Gauff had an easier time of it as she dismissed Tatjana Maria 6-4 6-1 on another day interrupted by the rain.

Second seed Sloane Stephens was only able to get through three games before play was suspended in her match against Rebeka Masarova, while fifth seed Wang Xiyu was 5-3 down in the first set against Karolina Muchova when the rain came.

Fourth seed Bernarda Pera is out after her match with Viktoria Kuzmova resumed having being washed out on Monday, and the American was unable to prevent a 6-4 6-4 defeat, with Kuzmova advancing to face Raducanu in the last 16.

The only two other matches completed on Tuesday saw Elena-Gabriela Ruse beat Erin Routliffe in three sets, and Anna Blinkova overcome Elisabetta Cocciaretto, also in three.

At the Adelaide International, Zheng Qinwen earned a hard-fought victory against number six seed Anett Kontaveit, eventually winning 6-1 4-6 7-6 (9-7).

Eighth seed Ekaterina Alexandrova also crashed out despite winning the first set against Marketa Vondrousova, going on to lose 4-6 6-3 6-2, though seventh seed Jelena Ostapenko is through after beating Karolina Pliskova 6-1 6-3.

In a contest that lasted over two-and-a-half hours despite only two sets being played, Victoria Azarenka beat Anhelina Kalinina 7-6 (11-9) 7-6 (7-5), and will face Zheng next, while Sorana Cirstea will go up against top seed Ons Jabeur in the last 16 after beating Viktorija Golubic in straight sets.

Linda Noskova produced the biggest win of her career as she defeated Daria Kasatkina 6-3 6-7 (2-7) 6-3 at the Adelaide International on Monday.

The 18-year-old Czech was impressive against the third seed as she recorded her first win against anyone in the top 30 of the world rankings.

Fourth seed Veronika Kudermetova eased past Amanda Anisimova in just an hour and 15 minutes, winning 6-3 6-0, while Liudmila Samsonova will face second seed Aryna Sabalenka in the next round after coming from a set down to beat Zhang Shuai 5-7 6-3 6-0.

Irina-Camelia Begu and Elena Rybakina also both came from behind to secure wins, with the latter beating fifth seed Danielle Collins to set up a last-16 clash against Ukrainian Marta Kostyuk, who beat Jaimee Fourlis 6-1 3-6 6-4.

At the ASB Classic in Auckland, 42-year-old Venus Williams comfortably overcame her 21-year-old opponent Katie Volynets 7-6 (7-4) 6-2, and will play China's Zhu Lin next after she eliminated sixth seed Madison Brengle 4-6 7-6 (8-6) 6-4.

Third seed Leylah Fernandez beat Brenda Fruhvirtova 6-1 6-1 to set up a last-16 tie with Julia Grabher after she defeated Tereza Martincova in three sets.

Eighth seed Rebecca Marino is through after beating Dalma Galfi in straight sets and will now face Ysaline Bonaventure, who eventually put away Caty McNally 5-7 6-4 6-4.

Viktoria Kuzmova led fourth seed Bernarda Pera 5-4 in the opening set when rain stopped play for the day.

Bianca Andreescu was denied her first WTA singles title since the 2019 US Open when Caroline Garcia fought back from behind to win a thrilling Bad Homburg Open final.

Garcia won her first WTA crown for three years by recovering to win a close encounter 6-7 (5-7) 6-4 6-4 on Saturday.

Andreescu went into the final as the strong favourite, a position she strengthened by narrowly claiming the first-set tie-break, but Garcia battled back to improve her impressive career record in finals to 8-3.

She claimed her first trophy since winning on the Nottingham grass in 2019, the same year as Andreescu's famous Flushing Meadows triumph.

Andreescu was playing in her sixth career showpiece, having enjoyed a standout week at the WTA 250 event. The Canadian did not drop a set en route to the final, which included beating top seed Daria Kasatkina.

But defeating the battling Garcia, who had saved a match point before beating fellow Frenchwoman Alize Cornet in the semi-finals, proved a step too far.

After winning three straight points to claim a tight tie-break, Andreescu was a break ahead at 4-2 in the second set before Garcia launched a strong comeback.

Andreescu was also a break up in the final set but Garcia – who broke five times throughout the contest - prevailed in two hours and 42 minutes.

With Wimbledon approaching, Andreescu was playing just her sixth tournament of the season following a six-month hiatus to look after her mental health that had followed a string of injuries over recent years.

Reigning Eastbourne International champion Jelena Ostapenko will go up against Petra Kvitova in 2022 Saturday's final.

Ostapenko won as a wildcard in 2021, and the world number 14 confirmed her place in this year's showdown by overcoming Camila Giorgi on Friday.

She is the first female player to reach back-to-back finals in Eastbourne since Caroline Wozniacki in 2017 and 2018.

The Latvian, who is also going to compete for the doubles title, prevailed 6-2 6-2 and will now go up against Kvitova. The pair have faced off eight times previously, with each player winning four matches.

It is Kvitova's first appearance in a final in 2022, with the former world number two – and two-time Wimbledon champion – having ended Beatriz Haddad Maia's winning streak.

Haddad Maia won in Birmingham last week and Nottingham the week before, but her run came to an end at 12 matches, with Kvitova triumphing 7-6 (7-5) 6-4.

"For me, a final after almost a year [without one] will be great, so I’m glad already," said Kvitova, who was a runner-up at Eastbourne in 2011 and last reached a final on grass in Birmingham four years ago.

"Jelena loves to play here, obviously, we saw it, she has a really great game for grass."

Meanwhile, at the Bad Homburg Open, 2019 US Open champion Bianca Andreescu reached her sixth career final courtesy of a walkover against Simona Halep.

The Romanian withdrew from the semi-final clash with a neck injury, which will worry the 2019 Wimbledon champion ahead of the season's third grand slam at the All England Club.

"I am sorry that I had to withdraw today before my semi-final match," Halep said in a statement.

"But unfortunately I woke up this morning with a blocked neck and this is not allowing me to perform to the best of my ability."

Andreescu will face Caroline Garcia, who saved a match point before going on to beat fellow Frenchwoman Alize Cornet 7-6 (11-9) 3-6 7-5 to reach an 11th tour-level showpiece.

Serena Williams lauded her doubles partner Ons Jabeur after they advanced to the semi-finals of the Eastbourne International on Wednesday. 

Playing in her first tournament since retiring from the opening round of Wimbledon injured last year, Williams acknowledged she was particularly reliant on Jabeur during their 6-2 6-4 success over Shuko Aoyama and Chan Hao-ching. 

The 23-time grand slam singles champion opted to only play doubles on the south coast as she gears up for a return to the All England Club. 

"I think we played together much better," said Williams. "Although I thought we played really good together [against Maria Bouzkova and Sara Sorribes Tormo on Tuesday] too. 

"But Ons really held me up. She was really playing so good. I was looking at her and was like, 'Wow, this is great.' It's good." 

Williams and Jabeur will take on Aleksandra Krunic and Magda Linette for a place in the final. 

Jabeur playfully asked the 40-year-old if she would like to play together at the US Open, to which the former world number one responded: "Sign me up!" 

The Tunisian added: "I'm getting used to this. It was really great to play here and I didn't know we are in the semi-finals. It's super fast, but it's great for us." 

Berlin Open top seeds Ons Jabeur and Maria Sakkari progressed with relative ease from their first-round matches, but Aryna Sabalenka and Garbine Muguruza were not so fortunate.

World number four Jabeur, who will team up with Serena Williams at the Eastbourne International, suffered a shock first-round exit at the French Open, but the Tunisian showed no signs of that defeat having affected her in her first grass-court appearance of the season.

Top seed Jabeur required just 73 minutes to overcome Karolina Muchova 6-3 6-3 on Tuesday, with American qualifier Alycia Parks next up after she defeated Qinwen Zheng in straight sets.

Second seed Sakkari, meanwhile, had a similarly comfortable start to her campaign, beating Leolia Jeanjean 6-3 6-2.

Meanwhile, reigning champion Liudmila Samsonova took her place in round two with a 7-5 6-1 victory over Tamara Zidansek.

Samsonova beat Belinda Bencic to claim the title in 2021, and the pair will meet again the quarter-finals should they win respective second-round ties against Veronika Kudermetova and Anna Kalinskaya.

But Kudermetova goes into her clash with Samsonova on a high, having eliminated third seed Sabalenka in a 2-6 7-5 6-4 comeback victory.

WTA Finals champion Muguruza will not be in round two after the Spaniard fell foul of Germany's Andrea Petkovic, who prevailed 7-6 (10-8) 6-4.

"I really do believe that in these really close matches, the simple and little shift of energy can make the difference," Petkovic said.

"If you have the crowd on your side, and they are willing you to the win somehow, I think that can really make a difference."

At the Birmingham Classic, top seed Jelena Ostapenko booked a second-round meeting with Dayana Yastremska.

While Yastremska beat Magda Linette in straight sets, Ostapenko was made to work, with the Latvian requiring two hours to overcome Canada's Rebecca Marino 6-2 5-7 6-3.

Fourth seed Elise Mertens was ditched out by Caty McNally, while former world number two and two-time major champion Petra Kvitova lost to Beatriz Haddad Maia.

Camila Giorgi, the third seed, leads Tereza Martincova after claiming a close first set 9-7 in the tie-break before the match was suspended.

Emma Raducanu will take on Iga Swiatek in an intriguing quarter-final at the Porsche Tennis Grand Prix but Maria Sakkari and Karolina Pliskova were eliminated. 

US Open champion Raducanu overcame Tamara Korpatsch 6-0 2-6 6-1 to set up a meeting with world number one Swiatek. 

It will be the pair's first meeting on the WTA Tour and Raducanu's maiden encounter with a top-10 opponent. 

The Briton, who is playing her first Tour-level clay-court event, won 90 per cent of points on her first serve in the opening set but that slipped to 56 per cent as she opened the door to a comeback in the second. 

However, Raducanu rediscovered her composure in the decider and got over the line after an hour and 39 minutes.

Fourth seed Sakkari retired while 6-4 3-1 down to home hope Laura Siegemund, who will take on Liudmila Samsonova after she bested Pliskova 6-4 6-4. 

Paula Badosa came through a third-set tie-break to beat Elena Rybakina 6-2 4-6 7-6 (7-4) and Aryna Sabalenka put a spanner in the works of Bianca Andreescu's comeback by taking their match 6-1 3-6 6-2. 

Ons Jabeur beat Daria Kasatkina and Anett Kontaveit eventually ousted Ekaterina Alexandrova in a tie-break finale after surrendering the first set.

At the Istanbul Cup, third seed Veronika Kudermetova was granted a walkover against Ana Bogdan.  

Seeds Ajla Tomljanovic (6) and Sara Sorribes Tormo (7) got past Lesia Tsurenko and Varvara Gracheva respectively, while there were also wins for Yulia Putintseva and Anastasia Potapova. 

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."

Petra Kvitova crashed out of the St Petersburg Ladies Trophy, but Jelena Ostapenko is safely through to the quarter-finals.

Two-time grand slam champion Kvitova was comfortably beaten in straight sets by Irina-Camelia Begu, with the Romanian winning 6-4 6-0 in just one hour and nine minutes.

The effectiveness of the first serve was the main difference-maker, with Begu winning 73.1 per cent of her first-serve points, while Kvitova – who has 28 singles titles to her name in contrast to her opponents' four – could only manage 50 per cent.

Begu was set to face the winner of Tereza Martincova's tie with Elena Rybakina, but the latter withdrew because of illness.

Seventh seed Ostapenko made light work of Andrea Petkovic as she beat the German 6-1 6-2 in just 58 minutes, helped largely by winning 85.3 per cent of her first serves, as well as saving all five of the break points she offered up.

Ostapenko has now won two of her four meetings with Petkovic and will next face Aliaksandra Sasnovich, who eased to a 6-2 6-3 victory over Jaqueline Cristian.

Maria Sakkari and Anett Kontaveit were among the big names to cruise through to the quarter-finals of the St Petersburg Ladies Trophy on Wednesday.

Top seed Sakkari faced Ekaterina Alexandrova in the second round and recorded a routine 6-2 6-4 triumph as she looks to bounce back from a fourth-round exit at the Australian Open. 

The Greek will next face a difficult contest with Elise Mertens, who needed three sets to see off the challenge presented by Petra Martic and seal a 6-4 3-6 6-2 success. 

Second seed Kontaveit recorded a 6-4 7-5 victory over Romania's Sorana Cirstea to set up a tantalising meeting with Belinda Bencic after the Swiss downed Kaja Juvan 6-1 7-6 (7-2). 

World number 12 Elena Rybakina, meanwhile, needed less than an hour to record a straight-sets victory over Varvara Gracheva, booking an encounter with Tereza Martincova in the round of 16. 

Ash Barty defeated Elena Rybakina in straight sets to claim the Adelaide International title, while Simona Halep clinched silverware in Melbourne.

World number one and heavy favourite Barty prevailed 6-3 6-2 against Rybakina to claim the Adelaide title for a second time in three seasons.

The 25-year-old recovered from 40-15 down in the seventh game and went on to immediately earn the only break of the opening set.

Barty did not look back as she held throughout the second set, meaning she went 35 consecutive games without losing serve to conclude the tournament.

After securing a 14th WTA singles title in a little over an hour, Barty now turns focus to next week's Sydney Tennis Classic ahead of beginning her Australian Open campaign.

"I feel good leading up to an Australian Open like I have every year," Barty, who hit 17 winners to 13 unforced errors, said after seeing off Rybakina. 

"Each and every preparation is unique. We take it for what comes and what it is, move on, try and do the best that we can in every opportunity.

"It has absolutely no effect on the way that I prepare or the way I'm thinking leading forward just because it's a Grand Slam. It doesn't change for us."

Halep, one of Barty's likely rivals for the Australian Open crown, also made a bright start to the year by overcoming Veronika Kudermetova in the Melbourne Summer Set 1 final.

The number two seed, who is aiming to put last year's injury-ravaged and trophyless season behind her, came out on top 6-2 6-3.

She recovered from an early break down in the first set and again in the second to make it 23 career titles, and a first since the 2020 Italian Open.

It could easily have been a different story, however, as Kudermetova had three break points to move 3-0 ahead in the second set, but the Russian could not take full advantage.

Amanda Anisimova defeated Aliaksandra Sasnovich at the Melbourne Summer Set 2 final to claim the first WTA title of the season, and her second overall.

Belarusian qualifier Sasnovich hit back in style to take the second set 6-1 after losing the opener 7-5, but Anisimova recovered from a break down to edge the deciding set 6-4.

In doing so, Anisimova became the first American to win a title on Australian soil since Sofia Kenin's Australian Open triumph in 2020.
