Second seed Elina Svitolina crashed out of the Viking International in Eastbourne at the last-16 stage on Wednesday with a straight sets defeat to Elena Rybakina.

The world number five lost 6-4 7-6 (7-3) to 21st-ranked Rybakina, whose reward is a meeting with Coco Gauff's conqueror Anastasija Sevastova in the quarter-finals.

Third seed Bianca Andreescu of Canada also lost in straight sets, Anett Kontaveit of Estonia beating her 6-3 6-3.

And it was the same story for fourth seed Iga Swiatek, though she at least took a set as she was beaten by Daria Kasatkina.

It took an impressive rally from Russia's Kasatkina to bounce back from losing the first en route to a 4-6 6-0 6-1 success.

She will now face Jelena Ostapenko, who beat Ons Jabeur 5-7 6-4 6-3.

In fact, top seed Aryna Sabalenka was the only seed to avoid a surprise exit on Wednesday as she cruised through.

The Belarussian, ranked fourth in the world, beat Alison Riske 6-1 6-4 in just over an hour to set up a clash with Camila Giorgi.

Giorgi had earlier followed up a win over defending champion Karolina Pliskova in the last round by beating Shelby Rogers 6-3 4-6 6-2.

There was no such string of shocks at Wednesday's other WTA event, the Bad Homburg Open in Germany, though first and second seeds Petra Kvitova and Victoria Azarenka needed three sets to progress.

Kvitova lost a second-set tie-break as she beat Ann Li 6-2 6-7 (4-7) 6-1 to reach the quarters, while Azarenka defeated Alize Cornet 6-4 3-6 7-6 (9-7).

Angelique Kerber, the fourth seed, progressed more smoothly, earning a comfortable 6-0 6-2 win over Russia's Anna Blinkova.

And Nadia Podoroska saw off the challenge of Patricia Maria Tig, winning 7-6 (7-4) 2-6 6-4.

Coco Gauff lost the first set in 20 minutes but roared back to stun seventh seed Elise Mertens – as Iga Swiatek also staged a comeback at the Viking International in Eastbourne.

Playing late in the day, Gauff was picked apart by Mertens to begin with, and also trailed by a break in the second set, but the 17-year-old American rising star pulled off a 0-6 7-6 (7-4) 7-5 first-round win.

Seeds Elina Svitolina, Bianca Andreescu and Swiatek all came through three-set matches on a busy day, but Karolina Pliskova was not so fortunate in her opener.

Winner of the grass-court event in 2017 and 2019, Pliskova arrived as the defending champion after last year's edition was cancelled amid the coronavirus pandemic.

However, her hopes of a repeat triumph came to an early end, beaten in three sets by qualifier Camila Giorgi.

The fifth seed was in charge initially against an opponent she had prevailed against in five of their six previous meetings, yet Giorgi produced an impressive response having fallen behind – aided by a strong service performance – to win 2-6 6-2 6-2.

Svitolina, the second seed, had lost in her previous two appearances in the main draw, and it appeared history could be repeated when Paula Badosa claimed the opening set against her.

Yet the second seed recovered to level, then dominated the tie-break in the decider to triumph 4-6 6-1 7-6 (7-1) and set up a second-round meeting with Elena Rybakina, who edged out wildcard Harriet Dart in three sets.

Andreescu, meanwhile, recorded her maiden win on grass in the main draw of a WTA tournament. The Canadian was made to work for it by Christina McHale, eventually coming out on top by a 6-4 2-6 6-2 scoreline.

Swiatek eventually saw off the challenge of Heather Watson after two hours and 42 minutes on court, a 6-3 6-7 (4-7) 7-5 triumph making sure of a place in the last 16. Watson led 4-1 and 40-0 in the decider but could not finish off last year's French Open champion.

This year's Roland Garros runner-up, Anastasia Pavlyuchenkova, meanwhile, was beaten 6-1 6-3 by Jelena Ostapenko.

At the Bad Homburg Open, second seed Victoria Azarenka defeated fellow Belarusian Yuliya Hatouka 7-5 6-0 to reach the last 16.

Jessica Pegula bowed out, though, as the American – seeded third – went down in a three-set tussle against Katerina Siniakova.

Barbora Krejcikova became the first woman for 21 years to win both singles and doubles titles at the same French Open as the Czech completed her staggering fortnight in Paris.

"We will have a little glass of champagne," said Krejcikova, the breakout star of Roland Garros this year, after she and Katerina Siniakova fended off Iga Swiatek and Bethanie Mattek-Sands in Sunday's doubles final.

A 6-4 6-2 victory for the Czech duo gave them a third women's grand slam title as a pair, and a second in Paris after their 2018 triumph.

Krejcikova was already established as a world-class doubles player, but it has been as a singles player that she has emerged in recent times, having only entered the WTA top 100 rankings for the first time last October.

A three-set victory over Anastasia Pavlyuchenkova in Saturday's singles final gave the world number 33 a first major title without a team-mate at her side.

The doubles triumph means the French Open women's title double has been achieved for the first time since Mary Pierce cleaned up in 2000, when the Frenchwoman beat Conchita Martinez in singles and paired up with Martina Hingis to beat Paola Suarez and Virginia Ruano Pascual.

The 25-year-old Krejcikova becomes just the seventh woman to clinch the double, after Billie Jean King, Margaret Court, Chris Evert, Virginia Ruzici, Martina Navratilova and Pierce.

Pierce wrote on Twitter: "Well done @BKrejcikova! Welcome to a very special club."

Krejcikova said she had not slept well after her singles triumph, and she felt not only tired but complained of "having some pains in my leg" after the doubles.

It has been a strenuous fortnight, and she was determined to finally unwind on Sunday evening.

"I think we going to have a dinner together this evening. We will have a little glass of champagne," she said.

"I already said I don't really drink but I think it's a time to actually celebrate it. I think we going to really enjoy ourselves.

"The rest, I just want to go back home. I just really have to relax. I have to spend some time with my family. After that, just start to work again."

Krejcikova will be a marked player at Wimbledon after her rapid rise in the rankings was capped by the slam success.

"I hope I'm going to have some chances on the grass, but I don't really know because I'm not that experienced on it," she said. "We will see.

"I just know from now on I can really enjoy because I have pretty much achieved everything I really wanted.

"Now I can just improve, that's the only thing I can do, just improving. All the guys and the ladies are doing. That's what I think."

Iga Swiatek blamed a gruelling recent schedule after her French Open defence ended in a shock quarter-final defeat to Maria Sakkari.

The Pole came into Wednesday's last eight match having won her last 22 sets at Roland Garros, but lost 6-4 6-4 to the competition's 17th seed.

Swiatek headed to Paris full of confidence after winning on clay in Rome two weeks prior, and she had also helped Bethanie Mattek-Sands into the semi-finals of this year's doubles.

However, the world number nine believes she may have paid the price for all that tennis in the form of a lacklustre display against Sakkari.

She said: "Well, obviously I didn't play my best tennis. That's for sure. But Maria did a good job with playing at my forehand, which wasn't working pretty well today.

"It's good for her that she saw that. She picked good tactics, for sure. I struggled with picking the right place where to play. I couldn't play some shots that usually give me points.

"Yeah, my balls weren't, like, really deep and heavy. Basically that's my biggest weapon, so it was really hard to play without that.

"Also, you know, I think, like, past couple weeks hit me kind of yesterday. I just didn't have good days, I couldn't do like physical recovery well because I was stressed. Days like that happen, and it's normal."

Swiatek left the court for treatment on her thigh after losing the first set, but she refused to blame that issue for her defeat.

She added: "Right now I know it's nothing serious. When I was on court, I felt it totally differently. As I said, I couldn't even sleep well yesterday. I slept like a few hours.

"I think I was feeling everything twice as much as I should. It was hard to rationally just see what's going on. I made the decision to tape it just to feel sure [to give] me, like, a little bit more confidence when I was moving.

"Still my reaction was bad. I didn't play well, like, tactically and also technically. I was on my heels, so it's hard to make something of that kind of game."

Sakkari, meanwhile, revealed that her commitment to simply enjoying Wednesday's match helped her secure a maiden Grand Slam semi-final berth.

She said: "I'm speechless - it is a dream come true. It is a very nice feeling, I couldn't have done it without my team and their support so I want to thank them.

"We still have a long way to go of course [if we want to win the tournament] but we made a huge step.

"I'm not going to tell you the game plan of course because we will play again [against Swiatek] for sure! So I'm not gonna say our little secrets!

"But I really enjoyed it. Before coming into the match I just sat down and spoke to myself and said it is a very important match but just enjoy it - playing at one of the best stadiums in the world. So I have enjoyed it."

Greece boasts two semi-finalists in this year's French Open after Stefanos Tsitsipas also progressed to the last four of the men's draw.

And Sakkari believes the sport may even have overtaken football and basketball in terms of popularity back in her homeland.

She continued: "Now it's probably the biggest sport these days. Football is over. Basketball is over. So tennis is in the spotlight.

"Yeah, with Stefanos, I mean, we're very close. We know each other since a very young age. I mean, I see him every day here. We're actually having dinner with our teams next to each other every night.

"I'm very, very happy for him and his family. It's very exciting times for Greek tennis."

Iga Swiatek saw the defence of her French Open title ended by a rampant Maria Sakkari in Paris.

Number 17 seed Sakkari was playing in her first grand slam quarter-final but showed no signs of nerves as she closed out a 6-4 6-4 victory against last year's champion in one hour and 35 minutes.

Sakkari will play unseeded Barbora Krejcikova in what will be a first major semi-final appearance for both players.

It was a scrappy start to the contest with both players struggling to establish a rhythm on serve.

Early breaks were exchanged before Sakkari had to save four break points in her next game to avoid another and Swiatek then fended off three in the next.

Sakkari looked a different player from then on as she seized control. At 4-4, a powerful forehand winner gave her two break points and she claimed the first of them.

After a first opportunity to move ahead was not taken as she served for the set, two big serves saved a break point and gave her another chance that was taken with a fine backhand, prompting huge emotion from the Greek.

Sakkari had the momentum and went 2-0 up in the second set, at which point Swiatek called for a medical timeout that resulted in a 10-minute delay.

After emerging with strapping on her right thigh, Swiatek looked more confident on her return, holding confidently before saving two break points in her next service game to remain in contention.

But Sakkari was undeterred, serving superbly and not allowing a single break-point opportunity in the second set, clinching a famous triumph that brought tears to her eyes with her third match point.

Data Slam: Swiatek streak ends

Having not dropped a set in any round of her successful campaign last year or in her four victories in 2021, Swiatek saw her streak of winning 22 consecutive sets in Paris abruptly halted. 

Still just 20, Swiatek will have many more opportunities but this result will have come as a shock to the system.

WINNERS/UNFORCED ERRORS
Sakkari – 26/24
Swiatek – 17/25

ACES/DOUBLE FAULTS
Sakkari – 5/2
Swiatek – 0/2

BREAK POINTS WON
Sakkari – 3/8

Andy Murray could hold the key to Iga Swiatek converting her clay-court mastery to the grass of Wimbledon.

Reigning French Open champion Swiatek has powered through to the quarter-finals this year at Roland Garros, and the 20-year-old looks the player to beat.

But soon attentions will switch from the clay in Paris to the grass of London, and Swiatek feels she could do with some pointers.

As Swiatek wrapped up a straight-sets win over Marta Kostyuk on Monday in Paris, Murray tweeted, "Love watching @iga_swiatek", followed by a heart emoji.

Swiatek responded: "Thank you Sir Andy! Are you by any chance up for a practice? I really need to improve my skills on grass."

Andy Roddick is also a fan of the 20-year-old Polish player, with the former US Open winner responding to Murray's initial tweet by saying: "Agreed. She is awesome."

Murray has been champion twice at Wimbledon, beating Novak Djokovic in 2013 and Milos Raonic in 2016.

It remains to be seen how Swiatek gets on when she heads to the All England Club, having made only one previous appearance there in the women's singles, losing in the first round to Viktorija Golubic two years ago.

She can point to some proven prowess, however, having been girls' champion in 2018.

Swiatek has a French Open campaign to complete before she can seriously begin to think about the grass, with a last-eight clash against Maria Sakkari coming up on Wednesday.
