In the midst of a brilliant season, world number one Iga Swiatek had another milestone to celebrate on Thursday when she beat Gabriela Lee at the Poland Open.

Swiatek's 6-3 6-2 win against her Romanian opponent was her 48th of the season, already equalling the best tally reached by a female player in the entirety of 2021.

The top seed will have a chance to go one better than Anett Kontaveit and Ons Jabeur from last season when she faces Caroline Garcia in the quarter-finals of her home tournament.

Garcia beat Elisabetta Cocciaretto 6-3 7-5, while Jasmine Paolini dug deep to see off Clara Burel 6-1 6-7 (1-7) 6-0.

There was a big upset at the Prague Open, as defending champion Barbora Krejcikova was eliminated in a 3-6 7-5 (7-5) 6-3 defeat at the hands of Nao Hibino.

Fellow Czech Lucie Havlickova was dispatched in straight sets by top seed Kontaveit, but Linda Noskova will keep the home flag flying after beating Alize Cornet.

Noskova's first career tour-level quarter-final will come against Krejcikova's conqueror Hibino.

Top seed Iga Swiatek brushed aside compatriot Magdalena Frech to advance to the last 16 at the Poland Open on Tuesday.

The Warsaw native took 73 minutes to secure a safe passage to the next round with a 6-1 6-2 victory, setting up a clash with Romanian Gabriela Lee – who defeated Raluka Serban on Tuesday.

Swiatek won 76.2 per cent of total service points and won 61.8 per cent of the overall points in the match, with Frech on the back foot throughout, extending her winning streak on clay to 17 matches.

It was Swiatek's first time on the court since defeat at Wimbledon to Alize Cornet, which brought an end to a remarkable 37-match unbeaten run.

Elsewhere, eighth seed Petra Martic overcame Weronika Falkowska 7-5 6-4, while there were also victories for Laura Pigossi, Elisabetta Cocciaretto, Sara Errani and Ana Bogdan.

In the Prague Open, Wimbledon quarter-finalist Marie Bouzkova advanced after a dominant 6-1 6-2 victory against Czech teenager Dominika Salkova - setting up a clash against another teenager, 19-year-old Russian Oksana Selekhmeteva.

There were also victories for Chloe Paquet, Wang Qiang and Magda Linette on day five of the tournament.

Top seed Anett Kontaveit took just 48 minutes to secure her place in the second round of the Prague Open, but Sorana Cirstea suffered a surprise loss. 

Defeated in the final of the Hamburg European Open last weekend, Kontaveit got straight back to winning ways in rapid time with a 6-0 6-1 win over Ekaterine Gorgodze. 

The world number two got 81.8 per cent of her first serves in, with the overwhelmed Gorgodze only able to win nine returning points across the entire match. 

Up next for Kontaveit is Lucie Havlickova after the Czech defeated compatriot Barbora Palicova 6-2 7-6 (7-5). 

Fourth seed Cirstea was sent packing from the first round by 19-year-old qualifier Oksana Selekhmeteva, whose 7-5 6-4 success was her first in the main draw of a WTA Tour event. 

Dominika Salkova marked her WTA main-draw debut with a 6-1 6-4 win over Ylena In-Albon, while Barbora Krejcikova delighted the home crowd with her 6-3 6-1 triumph against Anna Blinkova. 

Due to persistent rain, only three matches were completed at the Warsaw Open on Tuesday. 

Clara Burel, Ana Bogdan and Jasmine Paolini all advanced to the second round with wins over Anna-Karolina Schmiedlova, Nuria Parrizas-Diaz and Danka Kovinic respectively. 

Third seed Elise Mertens suffered a first-round exit at the Prague Open, while Caroline Garcia dispatched of Misaki Doi in the Poland Open. 

Mertens, who reached the fourth round at Wimbledon at the start of July, succumbed to a 6-3 2-6 6-2 defeat to Magda Linette – her first loss to the Pole after three straight-set victories in their previous encounters. 

The Belgian got just 52 per cent of her first serves in and won 38.5 per cent of points behind her second serve while only converting one of the five break points she earned. 

Sixth seed Alison Van Uytvanck retired in the first set of her match against Dalila Jakupovic, while eighth seed Marie Bouzkova overcame Sinja Kraus 6-2 7-6 (7-2). 

In Warsaw, fifth seed Garcia by no means had it easy in a 7-5 6-4 success over Doi. 

The Frenchwoman committed eight double faults and only got 55 per cent of her first serves in, but by saving six of the eight break points she faced she was able to get the job done in straight sets. 

Polish wildcard Maja Chwalinska was a 7-5 6-2 victor over qualifier Rebeka Masarova in only her second Tour-level tournament. 

Irina-Camelia Begu ended her five-year wait for another WTA title by beating home favourite Lucia Bronzetti to claim the Palermo Open crown.

The Romanian captured her fifth trophy on the tour – and a first since triumphing in her native Bucharest in 2017 – as she prevailed 6-2 6-2 in one hour and 33 minutes on Sunday.

This was Begu's ninth career final and her experience showed against Bronzetti, who was appearing in her maiden championship match.

The 31-year-old Begu broke her opponent's serve six times on the way to becoming the second Romanian to triumph on the WTA Tour this year, after Simona Halep captured a title in Melbourne in January.

Nerves were evident early on as the opening three games went against serve, before Begu held in the fourth to take command.

The sixth seed had been on court for over three hours as she overcame fourth seed Sara Sorribes Tormo in a thrilling late-night semi-final on Saturday.

She was well on top against Bronzetti, though, breaking again and winning 80 per cent of points when landing her first serve as she took the opening set.

World number 78 Bronzetti had taken out France's Caroline Garcia and Italian compatriot Jasmine Paolini to reach her maiden WTA final.

However, she had little answer to Begu, who broke twice early in the second set to establish a commanding 3-0 advantage.

Bronzetti broke back to reduce the deficit to 3-2, but the world number 45 pulled away again before a thumping ace sealed the deal.

Irina-Camelia Begu came from a set down to defeat Sara Sorribes Tormo 3-6 6-3 6-4 to set up a final against Lucia Bronzetti at the Palermo Ladies Open.

A contest that lasted three hours and 12 minutes, finishing just 20 minutes shy of 2am local time, began well for Sorribes Tormo, with the fourth seed taking the opening set.

The Romanian came storming back in the second though and was forcing her opponent all the way back to the advertising curtain with a series of deep shots, while also impressing on her own serve, getting 90 per cent of her first serves in across the set.

Begu ultimately served out to take it 6-3 as the local time went past midnight, but there was plenty more to come as a third set that moved at a glacial pace in the early hours of Sunday morning kept the more dedicated fans in the stands away from their beds.

An hour after the second set had concluded, the score in the third was just 3-2 to Begu after the sixth seed forced a break against Sorribes Tormo, who was warned with a time violation during the game.

That seemed to be a turning point as one break became two, before the Spaniard broke back to initially frustrate Begu, only for the Romanian to serve out victory at the second time of asking.

She will face Bronzetti in Sunday's final after the world number 78 also came from behind to win her semi-final with compatriot Jasmine Paolini.

It was a remarkable turnaround considering Paolini won the opening set 6-0, with Bronzetti only winning 33 per cent of points on her own first serve compared to Paolini's 79 per cent on hers.

However, Bronzetti found several more gears in the second set, winning 83 per cent on her first serve this time, and she carried that form into the third, recovering brilliantly to take the match 0-6 6-3 6-3.

Bernarda Pera claimed her second WTA title in as many weeks by defeating Anett Kontaveit 6-2 6-4 in the Hamburg European Open final.

The world number 81 continued her rich vein of form, having also captured the Budapest Grand Prix crown last weekend.

Pera, who won four out of six break points, stretched her winning streak to 12 matches, while she has also now reeled off 24 sets without reply.

Kontaveit had prevailed as a commanding straight-sets winner when the pair faced off in the opening round at Wimbledon four weeks ago.

Champion in St Petersburg and runner-up to Iga Swiatek in Doha, the Estonian became the fourth player to appear in at least three finals this season after Swiatek, Ons Jabeur and Veronika Kudermetova.

But the top seed was broken in the opening game by Pera, who won 16 out of 19 points on her first serve as she stormed through the first set.

The American then rescued two break points in the second set, while converting two of her own to secure consecutive breaks and move to the brink of the title.

Kontaveit dug deep; breaking back and winning eight of the next 11 points to stay alive at 5-4, but a long forehand in the next game sealed the deal for Pera.

Second seed Yulia Putintseva was eliminated from the Palermo Ladies Open at the quarter-final stage by Diane Parry on Thursday.

Putintseva was the strong favourite to overcome world number 86 Parry, but it was the latter who prevailed 6-3 6-4 to reach her first tour-level quarter-final.

Caroline Garcia also advanced through after recovering from a heavy first-set loss to overcome Elisabetta Cocciaretto 0-6 6-3 6-4.

Home hope Lucia Bronzetti awaits in the final eight following a 6-1 6-3 win over Elina Avanesyan, while Nuria Parrizas-Diaz beat Julia Grabher 6-2 6-4 in the day's other match.

At the Hamburg European Open, in-form Bernarda Pera beat Katerina Siniakova 6-3 6-1 to make it 10 wins in a row without dropping a set.

Pera is through to her second semi-final in a row, where she will take on Maryna Zanevska, who saw off Aliaksandra Sasnovich in straight sets for a second career top-50 victory.

Top seed Anett Kontaveit advanced after Andrea Petkovic withdrew injured when 6-0 2-0 down, but Barbora Krejcikova was on the end of a 6-1 6-3 upset against Anastasia Potapova.

Anett Kontaveit cruised into the quarter-finals of the Hamburg European Open with a straight-sets win over Rebecca Peterson, while third seed Zhang Shuai was forced out of the Palermo Ladies Open through injury.  

World number two Kontaveit recorded a 6-3 6-2 victory over Peterson on the clay in Germany, setting up a last-eight meeting with eighth seed Andrea Petkovic. 

The Estonian's win was her third over Peterson and maintained her 100 per cent career record against Swedish opponents, taking her to seven such successes. 

Kontaveit was joined in the quarter-finals by fellow seeds Aliaksandra Sasnovich, who beat Aleksandra Krunic 6-3 6-2, and Maryna Zanevska, who downed Alexandra Cadantu-Ignatik 6-4 6-1. 

They will face off for a semi-final spot on Thursday, while Anastasia Potapova will meet 2021 French Open champion Barbora Krejcikova after beating Maria Carle in straight sets. 

At the Palermo Ladies Open, meanwhile, third seed Zhang withdrew from her last-16 clash with home favourite Jasmine Paolini before taking to the court, citing an unspecified injury. 

Fellow seeds Sara Sorribes Tormo and Anna Bondar both reached the quarter-finals with straight-sets wins, however, with the pair set to face off for a semi-final berth on Friday.  

Serena Williams has been named on the entry list for the US Open.

The 23-time grand slam champion withdrew from last year's tournament at Flushing Meadows with a torn hamstring, but she has entered this year's with a protected ranking of 16.

Williams has also been named among the initial entry list for August's Cincinnati Masters as she returns to the US Open Series.

Former US Open champions Naomi Osaka, Bianca Andreescu and Emma Raducanu will also be present in Ohio.

Williams returned to action after almost a year away from the game in the WTA event in Eastbourne in June in the women's doubles, before competing in the singles at Wimbledon.

Following an exciting defeat to Harmony Tan in the first round on Centre Court at SW19, Williams said she was aiming for a US Open return. 

"When you're at home, especially in New York, and the US Open, that being the first place I've won a grand slam, is something that's always super special" she said. "There's definitely lots of motivation to get better and to play at home."

The 40-year-old will also compete at the Canadian Open next month as she ramps up her preparations for the US Open.

Venus Williams will make a long-awaited singles comeback at the Canadian Open next month.

The seven-time grand slam champion has not played a singles match since she lost to Hsieh Su-Wei in the first round at the Chicago Women's Open last August.

But she returned from a leg injury to partner Jamie Murray in the mixed doubles at Wimbledon earlier this month, reaching the second round.

The 42-year-old will be back in singles action in Toronto, where the Canadian Open begins on August 8.

Williams' sister, Serena, will also play in the tournament three weeks before the US Open gets under way.

After being handed a wild card, Venus will join the likes of world number one Iga Swiatek in a strong field.

The American made her debut in the hard-court event as a 15-year-old back in 1995, losing to Sabine Appelmans in the first round.

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.

Daria Kasatkina revealed she is in a gay relationship as Russia's leading star on the WTA Tour attacked homophobic attitudes in her homeland, and called for the war in Ukraine to end.

In an emotional interview with documentary maker Vitya Kravchenko, Kasatkina, who lives in Barcelona, teared up at the prospect of potentially being unable to return to Russia after being so candid.

The recent French Open semi-finalist has won four WTA titles in her career, including trophy runs at the Kremlin Cup in Moscow and the St Petersburg Open.

She has spoken about matters of sexuality in the past, and when asked whether she has a girlfriend, Kasatkina said in the new documentary: "Yes."

On her social media accounts, Kasatkina confirmed she and Olympic figure skater Natalia Zabiiako, who she described as "my cutie pie", are a couple.

She knows LGBT matters are taboo in Russia, saying: "So many subjects are taboo in Russia, some of them more important than ours, it's no surprise.

"This notion of someone wanting to be gay or becoming one, so ridiculous I think. There's nothing easier in this world than being straight.

"Seriously, if there is a choice, nobody would choose being gay. Why make your life harder, especially in Russia? What's the point?"

Asked whether she would be able to hold hands with her girlfriend in Russia, Kasatkina said: "Never."

Assessing the process of coming out, the 25-year-old said: "It's up to you how to do it and how much to tell. Living in peace with yourself is the only thing that matters, and f*** everyone else."

Few Russian sports stars have spoken out against the invasion of Ukraine, but Kasatkina made it clear that she feels strongly the war must stop.

Asked what she wanted most of all, Kasatkina said: "For the war to end. There hasn't been a single day since February 24 that I haven't read some news myself. Or haven't thought of it. [I want] for the day to just pass by without it.

"What people go through there, people that have relatives in Ukraine, especially when you start talking about Russia, Belgorod, here we go again. I can't imagine what they're going through, it's a full-blown nightmare.

"If only we could do something to stop that, even tiny percentage to stop. Not to change people's minds or something, only stop. Without a thought, I'd do anything, but unfortunately that's impossible and I think you understand it. We can't affect it. We can't change events that unfold. You feel powerless."

When she was asked by Kravchenko whether she was afraid she might not be allowed back to Russia because of her criticism, Kasatkina said: "Yes, I have thought about it."

She broke down in tears at that point.

Kasatkina has found support for coming out, with former doubles star Pam Shriver among those thanking her. She was also praised by Russian women's national team footballer Nadya Karpova, who has spoken about her own lesbian life and has also been a critic of the war.

Karpova posted on Instagram: "You are beautiful! I'm proud."

Kasatkina thanked Karpova in the YouTube documentary, saying: "Not only did Nadya help herself by coming clean and getting this burden off her chest, but she helped others.

"I believe it's important the influential people from sports, or any other sphere really, speaks about it. It helps."
