Anett Kontaveit and Barbora Krejcikova both breezed through at the Hamburg European Open, while Yulia Putintseva eased into the Palermo Ladies Open second round.

Top seed Kontaveit overcame world number 61 Irina Bara in straight sets in her first-round clash and third favourite Krejcikova followed suit in her second-round match against Poland's Magdalena Frech.

Kontaveit will meet Sweden's Rebecca Peterson in the next round as she looks to set up a quarter-final meeting in Germany with eighth seed Andrea Petkovic, who defeated Misaki Doi 6-4 6-3 on Tuesday.

There was no such luck for ninth seed Elena Gabriela Ruse, though, after she lost 6-0 6-4 to last week's Budapest Grand Prix winner Bernarda Pera.

Swiss Joanne Zuger will next be the next challenge for Pera as she aims to reach a quarter-final clash against Katerina Siniakova, who triumphed 6-1 6-1 over Brazil's Laura Pigossi.

Putintseva is ranked as the second favourite in Italy and progressed with ease from her first-round clash against world number 147 Jaimee Fourlis, winning 6-3 6-1.

Seventh seed Anna Bondar had little difficulty beating Clara Burel 6-4 6-4, though Caroline Garcia and Nuria Parrizas Diaz faced more difficult tasks in their respective openers.

France's Garcia, the fifth favourite in Palermo, responded to a first-set scare to defeat compatriot Chloe Paquet, while eighth seed Parrizas Diaz also lost her opening set before downing Asia Muhammad.

Reigning champion Yulia Putintseva's Budapest Grand Prix title defence came to a disappointing end after she was beaten in the semi-final in straight sets by Aleksandra Krunic.

The Kazakh Putintseva struggled to get going, failing to convert any of her seven break points, as the Serbian Krunic broke her serve four times en route to a 6-2 6-2 win.

Bernarda Pera will await Krunic in the final in Hungary, after her 6-3 6-4 victory over Anna Bondar.

Bondar raced out to an early 3-0 lead in the first set, but Pera rattled off six games in a row to take the opener.

The Croatian-born American then won the first three games of the second set, before overcoming a desperate late Bondar charge to break her at 5-4 and finish things off.

Sunday's final will be the third meeting between Krunic and Pera with the latter winning both of the previous contests, firstly in the quarter-finals of the Guangzhou Open in 2018 and then in Moscow in 2021.

At the Ladies Open Lausanne, qualifier Olga Danilovic cruised through to the final with a 6-3 6-2 victory over Russian Anastasia Potapova.

Danilovic won her first WTA Tour singles event in Moscow in 2018, overcoming Potapova after three sets.

And the world number 124 was victorious against Potapova once more in Switzerland to seal her place in her second WTA Tour singles final.

The Serbian 21-year-old will meet Petra Martic in the decider on Sunday after Martic overcame sixth seed Caroline Garcia 6-4 1-6 6-3.

Neither player had dropped a set on their way to the semi-finals, but things at Lausanne were tied up at one set each after two.

Garcia had won all three of her previous meetings with Martic, but the Croatian's two crucial breaks of serve in the final set were telling, as she held her nerve to reach the final against Danilovic.

Yulia Putintseva recovered from a set behind to overcome Laura Pigossi and keep her Budapest Grand Prix title defence alive.

The Kazakh player took time to get going but eventually prevailed 4-6 6-1 6-2 against her Brazilian opponent in the last-16 clash to make it seven wins in a row in the competition.

While the third seed was able to bounce back, there was no such luck for Chinese sixth seed Zhang Shuai as she was soundly beaten 6-1 6-0 by Serbian Aleksandra Krunic.

China's Wang Xiyu awaits Krunic in the quarter-finals after beating Romanian Ana Bogdan 7-6 (7-2) 7-6 (12-10) in a match lasting two hours and 43 minutes.

Elisabetta Cocciaretto was also victorious on Thursday, the Italian seeing off Wimbledon doubles champion Katerina Siniakova 7-5 4-6 7-5 in the final match of the day.

At the Ladies Open Lausanne, surprise Wimbledon singles quarter-finalist Jule Niemeier made it through to the last eight of another tournament, enjoying a 6-4 6-2 triumph against fellow German Eva Lys.

Caroline Garcia made it through to her fourth quarter-final of the year with a 6-1 6-4 win over French compatriot Leolia Jeanjean.

Qualifier Olga Danilovic saved a match point before going on to beat Anna Kalinskaya 6-3 3-6 7-5, while Belinda Bencic advanced from an all-Swiss battle with a 6-3 6-4 win over Susan Bandecchi.

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. 

World number one Iga Swiatek beat Victoria Azarenka 6-4 6-1 to progress to the quarter-finals of the Internazionali d'Italia in Rome on Thursday. 

Swiatek, who became the first female player to win 25 consecutive matches since Serena Williams in 2015, will face Bianca Andreescu in the last eight after she eased past Petra Martic 6-4 6-4.

"I didn't start well, and everybody could see that," Swiatek told reporters. "I'm really happy with the way I reacted and how I improved in the first set.

"Also how different the second set looked to the first one because I could really reset and really change the way I played. That's the most positive thing for me."

There was a shock in the final game of the day, though, as Daria Kasatkina dumped out number two seed Paula Badosa 6-4 6-4. 

Third seed Aryna Sabalenka sealed a third straight win over Jessica Pegula, easing to a 6-1 6-4 victory, while fourth seed Maria Sakkari defeated Coco Gauff 6-4 7-5.

Seventh seed Danielle Collins was knocked out by unseeded compatriot Amanda Anisimova, the 20-year-old cruising past the Australian Open finalist 6-2 6-2.

There were also victories for Jil Teichmann, who overcame Elena Rybakina 6-7 (3-7) 6-3 7-5, and ninth seed Ons Jabeur, who beat Yulia Putintseva 6-3 6-2.

Iga Swiatek and Paula Badosa progressed to the third round of the Internazionali d'Italia with ease as the former continued her impressive winning run on Wednesday.

Top seed Switaek, seeking a fifth consecutive title, breezed past Elena-Gabriela Ruse 6-3 6-0 as she became the first female player to win 24 consecutive matches since Serena Williams in 2015.

Badosa followed suit by dispatching Aliaksandra Sasnovich 6-2 6-1 in just an hour and 17 minutes, teeing up a third-round clash with Daria Kasatkina, who beat Leylah Fernandez 4-6 6-3 7-6 (7-2).

Aryna Sabalenka, the third favourite in Italy, also made light work of Zhang Shuai to triumph 6-2 6-0, while fourth seed Maria Sakkari cruised past Madrid Open semi-finalist Ekaterina Alexandrova 6-3 6-2.

Sakkari will next face a Rome rematch with Coco Gauff, who defeated compatriot Madison Brengle 6-2 6-4. Teenager Gauff's sole win against Sakkari came at this tournament in the second round last year.

Yulia Putintseva came from behind to beat Garbine Muguruza 3-7 7-6 (7-4) 6-1, and will next meet Ons Jabeur, who made it eight successive main-draw wins by defeating Ajla Tomljanovic 7-5 6-2.

Seventh seed Danielle Collins also battled past former world number one Simona Halep 7-6 (7-1) 6-3.

There was no such joy for fifth seed Anett Kontaveit as she crashed out to Petra Martic in straight sets, while Jil Teichmann upset former Rome champion Karolina Pliskova in a three-set thriller.

Belinda Bencic, who was ranked as 12th seed, was another early casualty as she fell to a 7-6 (7-4) 6-1 defeat against American Amanda Anisimova.

Meanwhile, Jessica Pegula secured her third-round spot after Anhelina Kalinina withdrew due to injury, with Victoria Azarenka earning a straightforward 6-2 6-4 victory over Camila Osorio to get a shot at favourite Swiatek in the next round.

World number one Iga Swiatek maintained her impressive form by seeing off Aryna Sabalenka in straight sets in Sunday's Stuttgart Open final to win a fourth straight WTA title.

Swiatek was made to work hard in Saturday's semi-final against Liudmila Samsonova as she dropped a rare set, but she was back to her imperious best against Sabalenka.

The 20-year-old prevailed 6-2 6-2 in 84 minutes to make it 23 victories in a row – only five other different players have enjoyed longer winning runs since 2000.

With her latest triumph in Germany, Swiatek has now won 30 WTA matches in 2022, compared to 36 in the whole of 2021.

She has won the Qatar Ladies Open, Indian Wells and Miami Open in straight succession, having also reached the semi-finals of the Australian Open in January.

Sabalenka, who eliminated Paula Badosa, Anett Kontaveit and Bianca Andreescu en route to the final, was the latest player to fall short in trying to stop the sublime Swiatek.

After saving a break point in the opening game, Swiatek held serve and broke her opponent in the next game before comfortably seeing out the first set.

The Pole never looked under serious threat in the second set as she took the last four games to down world number four Sabalenka, who lost to Ash Barty in this final last year.

At the Istanbul Cup, meanwhile, Anastasia Potapova beat Veronika Kudermetova 6-3 6-1 to clinch her maiden career title.

Qualifier Potapova recovered from a set down to beat Yulia Putintseva in Saturday's semi-final and was too strong for Kudermetova in what was her third career final.

Kudermetova broke Potapova early on and led 3-1 in the opening set, but the latter soon found her range and took advantage of some sloppy mistakes from her opponent.

After battling to victory in the first set, Potapova looked far more comfortable in the second as she produced a number of impressive shots en route to a breakthrough triumph.

Naomi Osaka produced a spirited performance as she defeated Sloane Stephens in three sets at Indian Wells on her return to the court.

Osaka was in action for the first time since a shock early exit at the Australian Open in January, but she ultimately had too much for Stephens in a 3-6 6-1 6-2 success.

Stephens initially looked the sharper of the two former major champions in the second-round clash, impressively taking a first-set lead, but Osaka found her groove after a slow start to level the contest.

Osaka then had to save three break points at 2-0 down in the decider, and that appeared to inspire another surge as she rattled off six successive games to roar to an emphatic win.

Shelby Rogers got past Nuria Parrizas-Dias in almost three hours, winning 6-1 5-7 7-6 (7-3), and last week's Monterrey Open runner-up Camila Osorio retired down 6-4 5-0 against Aliaksandra Sasnovich.

Yulia Putintseva got past Ashlyn Krueger 6-3 6-2 and Ukraine's Marta Kostyuk won in three hours and nine minutes over Maryna Zanevska 6-7 (5-7) 7-6 (8-6) 7-5.

Last month's Abierto Zapopan runner-up Marie Bouzkova eased past China's Wang Qiang 6-3 7-6 (7-5), while American Amanda Anisimova defeated compatriot Emma Navarro 6-2 6-2.

Top-seeded Elise Mertens rolled into the semi-finals at the Silicon Valley Classic with a 6-3 7-6 (10-8) win over Yulia Putintseva on Friday. 

The Belgian already has collected a pair of grand slam doubles titles this year at the Australian Open and Wimbledon and is seeking her seventh career singles crown. 

She will need to get past fourth seed Daria Kasatkina to have a chance. 

The Russian outlasted Magda Linette 6-4 3-6 6-4 in her quarter-final and is seeking her third title of 2021 after a three-year drought between wins. 

The other semi-final will match seventh seed Danielle Collins against qualifier Ana Konjuh.

Collins pulled out a tight 7-6 (7-5) 7-6 (7-4) upset of second seed Elena Rybakina to reach the semis in San Jose for the second time. 

The American won her eighth consecutive match after taking the title at Palermo two weeks ago. 

She will meet the only unseeded player remaining, Konjuh, who won the final 10 games of the match to close out Zhang Shuai 3-6 6-2 6-0. 

Top-seeded Elise Mertens pulled out a three-set win to reach the quarter-finals at the Silicon Valley Classic as all four matches went the distance on Thursday.

The Belgian, ranked 17th in the world, prevailed 6-2 4-6 6-4 over Kristina Mladenovic of France in two hours and 40 minutes to advance in San Jose.

She moves on to face the eighth seed, Yulia Putintseva, who rallied past Ajla Tomljanovic 3-6 7-5 6-3 as the Australian blew numerous chances to pull ahead by converting only two of 16 break-point opportunities.

In the bottom half of the draw, second seed Elena Rybakina remained on track with a 2-6 6-0 6-2 victory over American Claire Liu in a rematch of a second-round meeting at Wimbledon.

Rybakina next meets seventh seed Danielle Collins, a 3-6 6-4 6-3 winner over US countrywoman Sloane Stephens.

Stephens, the 2017 US Open champion, has slipped to number 67 in the world and was playing in her first tournament since Wimbledon as she prepares for a return to Flushing Meadows.

Danielle Collins eased past Shelby Rogers 6-4 6-3 to book her spot in the second round at the Silicon Valley Classic on Tuesday.

World number 36 Collins proved too strong for American compatriot Rogers, winning in one hour and 25 minutes.

Collins will meet another American in the second round, with Sloane Stephens up next.

Former U.S. Open winner Stephens beat Caty McNally 6-4 6-2 earlier in the day.

Yulia Putintseva, meanwhile, eased her way into the second round with a 7-5 6-3 win over Croatian Donna Vekic.

Putintseva will face Australian Ajla Tomljanovic in the second round after she fought back to overcome Amanda Anisimova 1-6 7-5 7-5.

France's Kristina Mladenovic won 6-4 6-4 over Han Na-Lae, while American Claire Liu won in three sets against Dayana Yastremska.

Mladenovic will face top seed Elise Mertens, while Liu meets second seed Elena Rybakina.

Yulia Putintseva was in devastating form as she crushed Anhelina Kalinina to win the Hungarian Grand Prix in Budapest, her second career singles title.

She needed just 70 minutes to thrash Kalinina 6-4 6-0 and seal a first WTA Tour triumph since 2019 when she was victorious in Nurnberg.

In fact, her semi-final appearance in Budapest was Putintseva's first since that success in Germany, and she rarely looked like passing up the chance for victory against her Ukrainian opponent.

Kalinina was as much her own worst enemy at times, with 34 unforced errors continuously handing the initiative to the ruthless Putintseva, who converted five of eight break points.

Two of those breaks came in the first three games of the match, and although Kalinina hit back initially, she could not sustain that form as Putintseva closed out the set.

The second set was far more one-sided, as Kalinina took just seven points across the six games, which were all won by Putintseva.

The Kazakh now turns her attention towards the Olympics.

In-form second seed Barbora Krejcikova saw off Wang Xinyu in straight sets on Saturday to set up an all-Czech final with Tereza Martincova on home soil at the Prague Open.

French Open champion Krejcikova needed just one hour and nine minutes to overcome Wang 6-1 6-2 and reach her third final in four tournaments.

Krejcikova controlled the match from the off, on her way to a routine win, with the world number 13 having still yet to drop a single set in the Czech capital.

Martincova had earlier been made to work a little harder for her victory over Greet Minnen, but the number eight seed advanced through to Sunday's final with a 6-3 6-4 win.

The 26-year-old let slip a 4-1 lead in the second set as Minnen pulled it back to 4-4, before taking her second match point with a strong forehand.

At the Lausanne Open, a new singles champion on the WTA Tour will be crowned on Sunday when Tamara Zidansek and Clara Burel face off.

Zidansek proved too strong for semi-final debutant Maryna Zanevska, prevailing 7-5 6-3, while Burel needed to dig deep to get the better of fifth seed Caroline Garcia.

Burel, who unlike Zidansek has never previously reached a WTA singles final at all, was a set and a break down to Garcia but recovered to take the match the distance.

The 20-year-old called a medical timeout in the decider, though she managed to put that behind her as she earned three breaks of serve to stun her French compatriot 5-7 6-2 6-2.

Elsewhere on Saturday, home favourite Dalma Galfi's tournament was brought to an end at the semi-final stage of the Hungarian Grand Prix with a 6-2 3-6 6-2 defeat to top seed Yulia Putintseva.

Wildcard entrant Galfi offered little in the first set to suggest she would push Putintseva all the way, but she did exactly that with a couple of breaks of serve in the second set.

However, Putintseva, looking to add to her only previous singles title at the 2019 Nuremberg Cup, stormed into a 5-1 lead in the deciding set and ended Galfi's hopes with her first match point.

The Russian will next take on Anhelina Kalinina, who led 6-7 (7-5) 4-1 against Danielle Collins in the other semi-final when her opponent withdrew injured.

Rebecca Sramkova handed number-one seed Petra Kvitova a shock defeat on home soil at the Prague Open to record her first WTA Tour-level win in a main draw since 2017.

The unseeded Slovakian took the first set 7-6 (7-5) before Kvitova bounced back to take the next 6-3. Sramkova, however, battled through injury to win the final set 6-4 and upset the two-time Wimbledon winner.

Seventh seed Nina Stojanovic avoided an early exit as she recovered from a first-set loss to beat Vitalia Diatchenko 6-7 (5-7) 6-1 6-3, while ninth seed Greet Minnen defeated Italian Giulia Gatto-Monticone 6-0 4-6 6-1.

Unlike Kvitova, the top seed at the Hungarian Grand Prix, Yulia Putintseva, cruised past Ekaterine Gorgodze 6-2 6-4 to record a straight-sets first-round win in Budapest.

But Irina-Camelia Begu, the fourth favourite, was not as fortunate as she failed to secure second-round progression, falling 3-6 4-6 to the unseeded Anna Karolina Schmiedlova.

The Hungarian Grand Prix provided more shocks, with Irina Bara knocking out eighth seed Sara Errani courtesy of a 4-6 7-5 6-2 triumph, while seventh seed Viktoriya Tomova crashed out to Paula Ormaechea in straight sets.

On day one of the Ladies Open Lausanne, favourite and 2021 Roland Garros semi-finalist Tamara Zidansek shook off a first-set loss to dispatch of Marina Melnikova 2-6 6-3 6-2 and book her place in the next round.

Meanwhile, second seed Fiona Ferro was leading her French compatriot Harmony Tan 7-5 2-1 before play was suspended for the day in Switzerland.

Bianca Andreescu had little trouble in her first outing on clay this season, easing past Andrea Lazaro Garcia at the Internationaux de Strasbourg.

Andreescu had been absent from the WTA Tour since making the final in Miami back in March, when she was forced to retire when a set and 4-0 down against Ashleigh Barty due to an ankle injury.

A positive COVID-19 test result ruled her out of competing in Madrid and also Rome, though the Canadian showed few signs of rust on her return.

The top seed defeated the world number 279 – who was making her main-draw debut after coming through qualifying – in just 61 minutes, a 6-1 6-2 triumph sealed in a hurry thanks to five breaks of serve.

Champion at the 2019 US Open, Andreescu did not play in any grand slam event last year. She has only featured in the main draw at the French Open once before, reaching the second round at Roland Garros two years ago.

"I feel really, really good," the world number seven said after an impressive opening display. "I had really good preparation coming into this tournament, so I'm super happy."

Also in action on Monday, Yulia Putintseva overcame Sweden’s Rebecca Peterson via a tie-break in the deciding set of their see-saw contest.

The fourth seed eventually prevailed 6-4 3-6 7-6 (7-2) after three hours and 20 minutes on court, booking her a spot in the last 16 of the tournament.

Zhang Shuai was successful in her first outing, beating Misaki Doi 7-5 6-4. Barbora Krejcikova was another seed to make it through, having led 6-3 3-0 when opponent Oceane Dodin retired.

Caroline Garcia overcame Zarina Diyas 7-5 6-2, while Maryna Zanevska needed less than an hour to overcome Yuliya Hatouka 6-2 6-1 and set up a clash with Andreescu.

Jil Teichmann was also a winner in straight sets against Anna Blinkova, but Venus Williams' campaign is over early after going out to Sorana Cirstea, who dominated a decider to triumph 6-1 2-6 6-1.
