It was a great day for the highly ranked Americans at the Guadalajara Open on Wednesday, headlined by world number five Jessica Pegula and her 2-6 6-3 7-6 (10-8) comeback win over Wimbledon champion Elena Rybakina.

Pegula, who is now locked into the top-eight and therefore will qualify for the WTA Finals, struggled to win points on her serve in the opening set, but raised her 57 per cent success rate up to 69 per cent in the second set, and 66 per cent in the decider.

The American had to come from a break down in the second set to keep her tournament alive, and she will now face Canada's Bianca Andreescu in the third round.

Meanwhile, fellow United States star Coco Gauff was too good for Italy's Elisabetta Cocciaretto, winning 7-6 (7-1) 6-3 to book a third-round clash with another Italian, Martina Trevisan, who earned her way there with a 6-0 4-6 6-3 win over Katerina Siniakova.

The other two seeded Americans were also successful, with 13th seed Madison Keys coming from a set down to defeat Ajla Tomljanovic 3-6 6-4 6-3, and 14th seed Danielle Collins repelled the challenge of Magdalena Frech 6-3 6-4.

There were positive signs for former world number five Eugenie Bouchard, who ended up losing, but showed she still has her talent by taking a set off world number 23 Jelena Ostapenko in a 7-5 2-6 6-1 result.

Russian pair Anna Kalinskaya and Liudmila Samsonova both emerged in three-set outings, with Kalinskaya outlasting Elise Mertens 6-4 0-6 7-5, while Samsonova upset world number four Aryna Sabalenka 6-4 2-6 6-2.

World number 12 Veronika Kudermetova kept her WTA Finals hopes alive with a 6-4 7-5 win over Donna Vekic, and the Czech Republic's Marie Bouzkova ousted Colombia's Camila Osorio 6-3 6-1.

In the late window, Sloane Stephens eliminated Olympic gold medalist Belinda Bencic 6-4 6-4, and top overall seed Paula Badosa retired due to injury after losing the first set 6-2 against Victoria Azarenka.

Belinda Bencic fought back to defeat Eugenie Bouchard in an Ostrava Open first-round contest that took over two and a half hours to settle.

Bouchard took the first set, but Bencic came from behind to advance with a 6-7 (7-9) 6-1 6-4 victory on Tuesday.

Eighth seed Jelena Ostapenko, runner-up in the Korea Open, suffered a premature exit as Aliaksandra Sasnovich consigned the former French Open champion to a 6-2 6-2 defeat.

Emma Raducanu also went out in straight sets, with Daria Kasatkina beating the 2021 US Open champion 7-5 6-4.

Catherine McNally blitzed to a 6-1 6-2 victory over Anna Blinkova, while Alycia Parks progressed past Karolina Pliskova to secure the first top-20 win of her career.

Top seed Ons Jabeur swept aside Ann Li with relative ease in a 6-2 6-3 victory at the Jasmin Open to reach the last 16.

Veronika Kudermetova, the second seed, breezed past Varvara Gracheva with a commanding 6-1 6-0 win.

Anastasia Potapova, Petra Martic, Magdalena Frech and Harriet Dart were among the other victors.

Korea Open finalist Jelena Ostapenko was knocked out in the first round of the Tallinn Open after letting a one-set lead slip against Kaia Kanepi.

Ostapenko looked to be cruising after winning the opener, but Kanepi levelled in the second despite the Estonian watching five set points come and go.

Kanepi then romped to victory with a stunning final set to defeat Ostapenko 4-6 6-4 6-0 and keep her hopes of winning her home tournament alive.

In second-round action, Beatriz Haddad Maia is through to the quarter-finals after a 6-1 7-5 success over Linda Noskova.

After Haddad Maia cruised to a one-set lead, the second was a much tighter affair before the Brazilian's class showed as she broke Noskova and then held serve to earn a straight-sets win.

Second seed Belinda Bencic also secured her place in the final eight with a 6-4 6-7 (2-7) 6-3 triumph over Katie Boulter.

At the Parma Ladies Open, top seed Maria Sakkari came from behind to beat Arantxa Rus and seal her quarter-final spot.

Rus saved five out of five break points as she won the opening set 6-3 to give her hope of an upset.

Those hopes were soon dashed though as world number seven Sakkari broke twice to take the second set 6-2, before clinching the match in the third to tee up a clash with Maryna Zanevska.

World number 33 Irina-Camelia Begu made it 12 consecutive wins on clay by overcoming Matilde Paoletti in straight sets and will face fellow Romanian Ana Bogdan in the next round after she beat Anna Karolina Schmiedlova 6-2 3-6 6-3.

Fourth seed Sloane Stephens saw her tournament come to an end after she was defeated by Danka Kovinic.

Ekaterina Alexandrova is aiming high after overcoming some early nerves to beat top seed Jelena Ostapenko in the Korea Open final for her third WTA Tour title.

The 27-year-old prevailed 7-6 (7-4) 6-0 in Seoul to add to previous titles won in Shenzhen and 's-Hertogenbosch, the latter coming just three months ago.

Alexandrova is at a career-high 24th in the WTA rankings and is hoping to climb further before the year is out.

"You always want to achieve more. I want to go higher and maybe end the year in the top 20 in the best-case scenario," she said in her on-court interview.

Ostapenko advanced to Sunday's final after Emma Raducanu retired injured in the previous round and was aiming to become the first two-time champion in the event.

Second seed Alexandrova dug deep in the first set by recovering from a break down three times against the 2017 winner before saving a set point at 6-5 down.

The Russian looked far stronger in the second set as she posted her sixth bagel of 2022 to seal victory in a time of 85 minutes.

"I think it was tough for me to start because I was really nervous and I couldn't find my rhythm in the first couple of games," Alexandrova said.

"But the longer we played, the better I felt on the court. I think maybe somewhere in the end of the first set I finally found the rhythm and I just continued to keep it that way."

Emma Raducanu was forced to retire from her Korea Open semi-final against Jelena Ostapenko due to injury, leaving the Latvian to face second seed Ekaterina Alexandrova in Sunday's final.

The 2021 US Open winner was featuring in her first semi-final since that fairytale triumph at Flushing Meadows, and took the opening set 6-4 after making a flying start on Saturday.

Ostapenko then fought back to level the match, with Raducanu first appearing to struggle with her movement when she was a break up in the second, forcing her to take an off-court medical timeout.

The 19-year old later retired citing a left glute injury when 3-0 down in the decider, ending her confidence-boosting run in Seoul and teeing up a final meeting between the top two seeds.

Indeed, Alexandrova enjoyed a more routine outing in her meeting with Wimbledon semi-finalist Tatjana Maria, downing the German 6-2 6-4 to advance to her second final of the year.

At the Pan Pacific Open in Tokyo, meanwhile, Chinese teenager Zheng Qinwen reached her first WTA Tour final with a hard-fought win over world number 13 Veronika Kudermetova.

Having required over three hours to seal her 5-7 6-3 7-6 (7-3) triumph, the world number 36 said: "After the match when I won the last point, the feeling was incredible. 

"The opponent, she's playing unbelievable tennis. She has a really good serve and hits the ball hard, she moves well. It's my first time in the final. I'm so happy."

Her compatriot Zhang Shuai was unable to replicate those exploits, however, as Liudmila Samsonova eased into her third WTA final of the year with a 7-6 (7-4) 6-2 win. 

In-form Samsonova has won both of her previous final appearances this year - each of which came last month - and is 3-0 in showpiece matches for her career.

Emma Raducanu raced into her first semi-final of 2022 by beating Magda Linette at the Korea Open, teeing up a meeting with top seed Jelena Ostapenko. 

Raducanu required just 77 minutes to see off the third seed for a 6-2 6-2 win, dominating from the outset to clinch her first final four spot in any tournament since last year's famous US Open triumph.

Having wrapped up the opener with a fierce backhand winner, Raducanu was forced to endure a brief revival from Linette in the second set, before the Pole was troubled by a thigh injury.

Linette lost 14 of the first 17 points on resumption after a medical time out, struggling with her movement as Raducanu saw out the match.

Raducanu has yet to drop a set during her run in Seoul, but will face a stern test in the semi-finals after Ostapenko overcame 17-year-old Victoria Jimenez Kasintseva 6-2 6-1, setting up a first career meeting between the duo.

On the other side of the draw, Ekaterina Alexandrova earned a hard-fought 7-5 7-6 (8-6) win over Lulu Radovcic, but fourth seed Zhu Lin crashed out to Tatjana Maria, losing 6-1 6-1.

In the Pan Pacific Open in Tokyo, meanwhile, Garbine Muguruza fell to a shock 6-4 6-2 quarter-final defeat to Liudmila Samsonova, handing the Russian her 16th win in her last 17 outings.

She will meet Zhang Shuai in the next round, after she became the first Chinese player to make the last four in Tokyo since 2009 by beating Petra Martic 7-5 6-2. 

In a battle between the competition's fourth and fifth seeds, meanwhile, Veronika Kudermetova rallied to beat Brazil's Beatriz Haddad Maia 6-7 (4-7) 7-6 (8-6) 6-1.

Naomi Osaka's title defence at her home Pan Pacific Open event came to a premature end as she withdrew from her second-round match against Beatriz Haddad Maia.

The former world number one, who won the Tokyo tournament when it was last held in 2019, was unable to compete in Thursday's match due to illness.

"I am really sorry that I am not able to compete today," Osaka said. "It's an honour to be able to play at the Pan Pacific Open in front of the amazing fans here in Japan.

"This has and always will be a special tournament for me and I wish I could have stepped on court today, but my body won't let me."

Haddad Maia advanced on a walkover and will next face fourth seed Veronika Kudermetova, who defeated Mexican qualifier Fernanda Contreras Gomez 6-0 6-1 to reach the quarter-finals.

Liudmila Samsonova also progressed to the last eight, with a 7-6 (7-5) 6-3 win over Wang Xinyu continuing her good form.

However, sixth seed Karolina Pliskova exited the competition on Thursday at the hands of Petra Martic, who prevailed 6-3 6-4 and will face Zhang Shuai next.

At the Korea Open, top seed Jelena Ostapenko recovered from two games down in the deciding set to overcome Anastasia Gasanova 6-3 5-7 7-5.

Ostapenko remains on a possible semi-final collision course with Emma Raducanu, who came through 6-4 7-5 against Yanina Wickmayer, while Magda Linette saved two match points to beat Kristina Mladenovic 4-6 7-6 (7-5) 6-2.

Naomi Osaka began the defence of her Pan Pacific Open crown with a quick win after opponent Daria Saville was forced to retire in just the second game.

Four-time grand slam champion Osaka won the opening game, before Saville was unable to continue due to a scary-looking injury to her left knee.

The former world number one will now face a second round match with world number 16 Beatriz Haddad Maia, who eased to a straight sets victory over Yuki Naito.

Karolina Pliskova secured her place in the next round in Tokyo with a 6-2 6-1 demolition of Isabella Shinikova, while Zhang Shuai will face second seed Caroline Garcia on Wednesday after overcoming Mai Hontama in two sets.

In Seoul, Jelena Ostapenko's hopes of repeating her 2017 heroics at the Korea Open are still alive after the number one seed narrowly beat 19-year-old Jeong Bo-young.

The world number 19 looked to be cruising after the opening set, but the unheralded South Korean hit back in the second and took it to a tie-break in the third, before Ostapenko's class showed as she won the crucial tie-break 7-2.

Elsewhere, 2021's beaten finalist Kristina Mladenovic saw off wildcard Park So-hyun 6-4 4-6 6-3, while second seed Ekaterina Alexandrova overcame a worrying second set to beat Asia Muhammad 6-1 3-6 6-1.

Wimbledon semi-finalist Tatjana Maria is also safely through to the second round after a tight 7-6 (7-5) 7-6 (7-5) triumph over Eugenie Bouchard.

Serena Williams highlighted the first day of the Canadian Open, defeating Nuria Parrizas-Diaz 6-3 6-4 for her first win since the 2021 French Open.

In doing so, Williams became the fourth player since 2000 to win a WTA-level main draw match after turning 40, joining sister Venus Williams, as well as Kimiko Date Krumm and Martina Navratilova.

She also claimed the all-time record for wins at the Canadian Open, with 35, now one more than Chris Evert.

"I guess there’s just a light at the end of the tunnel," Williams said after the match. "I don’t know, I’m getting closer to the light. Lately that's been it for me. I can’t wait to get to that light."

She added: "I love playing though, so it’s like amazing. But I can’t do this forever. Sometimes you just want to try your best to enjoy the moments and do the best that you can."

Williams' older sister Venus, 42, was beaten on Monday by Swiss Jil Teichmann 6-2 6-3 with the match finshing after midnight following a delayed start due to rain.

One of the three seeded players in action on Monday, 15th seed Simona Halep had no issues cruising through the challenge of Donna Vekic 6-0 6-2.

It was similarly smooth sailing for 14th seed Karolina Pliskova in her all-Czech showdown against Barbora Krejcikova, winning 6-3 6-4, while Latvian 16th seed Jelena Ostapenko handled the challenge of Ukraine's Anhelina Kalinina 6-4 6-2.

Kazakhstan's Elena Rybakina defeated in-form qualifier Marie Bouzkova 7-5 6-7 (3-7) 6-1, likely earning a shot at Coco Gauff if the American wins as a heavy favourite tomorrow, while Brazil's Beatriz Haddad Maia beat Italy's Martina Trevisan 6-2 2-6 6-2 in a meeting of two top-30 players.

In a pair of all-American battles, Sloane Stephens edged Sofia Kenin 6-2 7-6 (7-5) 7-5, and world number 187 Asia Muhammad upset world number 25 Madison Keys in straight sets 7-6 (7-5) 6-4.

Alize Cornet defeated her French compatriot Caroline Garcia 3-6 6-3 6-3, and Canada's Katherine Sebov was unable to get the job done in front of her home fans, going down 6-3 2-6 5-7 to Yulia Putintseva.

In better news for the Canadians, Leylah Fernandez won 6-4 6-7 (2-7) 6-3 over Storm Sanders, while veteran two-time Wimbledon winner Petra Kvitova was beaten by Alison Riske 6-2 4-6 6-3.

A tremendous performance from Petra Kvitova saw her ease past Jelena Ostapenko in straight sets 6-3 6-2 to win the Eastbourne International on Saturday.

Reigning champion Ostapenko had not dropped a set on the way to the final, but could not halt Kvitova, who was making her first appearance in a final in 2022.

The former world number two – and two-time Wimbledon champion – made a strong start, breaking Ostapenko early on and racing to a 3-0 lead in the first set.

Ostapenko, the Latvian number eight seed, faced eight break points in the opening set, saving seven, but she was unable to force any of her own as Kvitova comfortably served out to move ahead.

Kvitova was hitting the ball with immense power, particularly on returns, but Ostapenko showed initial improvement in the second set with her first serve accuracy, which had been down at 55.9 per cent in the first.

However, it was not enough to keep her opponent at bay as some more fierce returning from Kvitova saw her break in the third game of the second set.

Ostapenko finally threatened to break the Czech's serve, but was unable to take any of the five break points she earned in a game that lasted more than 12 minutes.

Her first serve dropped off again, which allowed the relentless Kvitova to take full advantage, breaking for a second time before serving for the championship and sealing her first-ever Eastbourne title.

It was Kvitova's 29th triumph on the WTA Tour, but her first since March 2021. Her last success on grass had come in Birmingham four years ago.

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.

Bianca Andreescu dismantled top seed Daria Kasatkina to reach the semi-finals of the Bad Homburg Open, while Beatriz Haddad Maia moved a step closer to a third straight title in Eastbourne. 

A resounding 6-4 6-1 win over Kasatkina saw Andreescu advance to the last four of a WTA Tour grass-court tournament for the first time. 

The last time she reached the semi-finals in any event was the 2021 Miami Open, where she finished as runner-up after retiring with an ankle injury in the second set of the final against Ash Barty. 

Andreescu limited Kasatkina to just 17.6 per cent of the points behind the Russian's second serve and saved four of the six break points she faced to book a meeting with Simona Halep. 

Former world number one Halep sent down 10 aces and converted all three of the break points that came her way in a 6-2 6-1 success over Amanda Anisimova. 

The other semi-final will be an all-French affair after Alize Cornet and Caroline Garcia downed home hopes Angelique Kerber and Sabine Lisicki respectively. 

After going all the way in Nottingham and Birmingham this month, Haddad Maia progressed to the semi-finals of the Eastbourne International courtesy of a walkover against Lesia Tsurenko. 

Next up for Haddad Maia is Petra Kvitova, who she beat in straight sets in the first round in Birmingham, after the Czech ended Harriet Dart's run to the quarter-finals with a 6-3 6-4 win. 

Jelena Ostapenko cruised to a 6-3 6-2 victory against Anhelina Kalinina and will take on Camila Giorgi for a place in the final. Giorgi comfortably overcame lucky loser Viktoriya Tomova 6-2 6-1 in 64 minutes. 

Garbine Muguruza saw her Wimbledon preparations take a hit as she fell to a last-16 defeat at the Eastbourne International on Wednesday. 

World number 26 Camila Giorgi battled from a break down in both sets to beat fifth seed Muguruza 7-5 6-3 in an hour and 53 minutes. 

That meant 12th seed Giorgi made her second straight quarter-final, following a last-eight appearance in Birmingham, and will next face Viktoriya Tomova, who defeated Kirsten Flipkens 3-6 6-3 6-4. 

Jil Teichmann, the 10th seed at the tournament, was a notable second-round elimination, falling to a 7-6 (9-7) 4-6 6-3 defeat to Briton Harriet Dart, who later triumphed 6-4 2-6 6-4 over Marta Kostyuk. 

Dart's fellow Briton Katie Boulter stunned last year's Wimbledon runner-up Karolina Pliskova in the second round but had no such luck against Petra Kvitova, losing 5-7 6-0 7-5. 

Beatriz Haddad Maia, the winner at the Birmingham Open last week, extended to a 12-match winning streak with a 6-1 6-2 victory over Jodie Burrage. 

Jelena Ostapenko also progressed after Madison Keys retired when 6-3 down and will next face Anhelina Kalinina, who battled to a 6-3 2-6 6-3 win over 16th seed Yulia Putintseva. 

While seeds fell at Eastbourne, there were not as many shocks at the Bad Homburg Open, where Angelique Kerber defeated Lucia Bronzetti 6-2 6-3 to reach the quarter-finals. 

Fourth seed Simona Halep also made the last eight with 6-0 6-3 victory over Tamara Zidansek and will meet Amanda Anisimova after she won an All-American match against Ann Li 6-0 6-2. 

Alize Cornet downed Tatjana Maria 7-6 (7-4) 6-4 to tee up a clash with Kerber, while Bianca Andreescu will meet top seed Daria Kasatkina after defeating Katie Swan 6-4 6-4. 

Katie Boulter stunned last year's Wimbledon runner-up Karolina Pliskova at the Eastbourne International as the Briton secured the first top-10 scalp of her career.

Despite making a strong start, fourth seed Pliskova faltered and lost 1-6 6-4 6-4 to the world number 127 in the pair's last-32 match.

Boulter said: "I'm super-proud of myself today. I went out there and didn't feel great on court, and I worked so hard to battle and fight, and against a player like that it means so much to me, coming through that."

There was another major shock win for a British player later in the day as Jodie Burrage knocked out top seed Paula Badosa, the world number 169 triumphing 6-4 6-3 against a player who will be seeded fourth at Wimbledon.

Defending champion Jelena Ostapenko beat Ajla Tomljanovic 6-4 6-4 and two-time Wimbledon winner Petra Kvitova saw off Donna Vekic 6-1 7-6 (7-1), while Beatriz Haddad Maia's strong form on grass continued with a 6-4 3-6 6-3 victory over Estonian veteran Kaia Kanepi.

Brazilian left-hander Haddad Maia is coming off the back of title wins in Nottingham and Birmingham and stretched her winning run on grass to 11 matches.

There were also wins in Eastbourne for Camila Giorgi, Madison Keys and Barbora Krejcikova, but Greek third seed Maria Sakkari bowed out, losing 3-6 7-5 6-4 to Ukrainian Anhelina Kalinina.

At the Bad Homburg Open in Germany, the 2019 Wimbledon champion Simona Halep scrambled for a 4-6 6-3 6-4 win against Katerina Siniakova, and sixth seed Amanda Anisimova came from a set down to see off Alison van Uytvanck in a third-set tie-break.

Bianca Andreescu saw off Martina Trevisan 6-3 6-1 and Angelique Kerber also won in straight sets, while top seed and recent French Open semi-finalist Daria Kasatkina reached the quarter-finals with a 6-1 3-6 6-1 win over Germany's Jule Niemeier.

Kasatkina will be absent from Wimbledon due to the ban on Russian players.
