British number one Johanna Konta says she faces a “great test” against former world number four Dominika Cibulkova in the Wimbledon second round on Thursday.

Konta plays the Slovak – who missed out on a seeding to Serena Williams – in the second match on Centre Court.

Kyle Edmund, Britain’s men’s number one, follows on the same court against American qualifier Bradley Klahn.

Briton Katie Boulter meets Naomi Osaka, while world number ones Rafael Nadal and Simona Halep also play.

Twenty four of the 64 seeded players – 12 men and 12 women, including five of the top 10 females – are already out.

Serena seeding has knock-on effect for Konta

Cibulkova is 32nd in the world rankings but is not seeded for Wimbledon after seven-time champion Williams was made the 25th seed.

“She’s probably one of the best competitors on tour, and has been for quite some time. She’s a feisty player,” said Konta.

“I think it will be a great test for me to keep a good kind of focus on controlling what I can, accept that she’s going to fight her way into some points and really stay there until the very end.”

Konta, 27, also reached fourth in the rankings last year after her memorable run to the Wimbledon semi-finals, but has since struggled for consistency and dropped to 24th.

Cibulkova, who said before the tournament it was “unfair” she was not given a seeding, says she is trying to forget about the controversy.

“It doesn’t make sense to think about it. I just have to play well to keep going in the tournament,” said the 29-year-old.

“Obviously it would be better to play Konta in the third or fourth round so it’s a very tough second-round match.

“I’m feeling fine on the grass. I would say it’s one of her favourite surfaces, but it’s also one of mine so let’s see what happens.”

Edmund could set up Djokovic clash

Edmund, 23, had won only one main-draw match at Wimbledon before beating Australian debutant Alex Bolt in straight sets on Tuesday.

The 21st seed now faces another qualifier in 27-year-old Klahn as he tries to reach the last 32 here for the first time in his career.

And he says there is “no reason” why he cannot start winning more matches on grass.

“When you have a big game or a big serve, you got to use that to your advantage, especially on a grass court,” said the Yorkshireman, who is ranked 17th in the world.

Victory over world number 168 Klahn, who was in the top 100 five years ago before a long-term injury, could set up a third-round meeting for Edmund against three-time Wimbledon champion Novak Djokovic.

The 12-time Grand Slam champion, who is seeded 12th, plays Argentina’s Horacio Zeballos, while Spanish second seed Nadal plays Kazakhstan’s Mikhail Kukushkin.

‘Underdog’ Boulter to enjoy Osaka test

Boulter, 21, earned her first Wimbledon victory by beating Paraguay’s Veronica Cepede Royg on Tuesday, setting up a tough match against Osaka.

They meet in the opening match on Court Two at 11:30 BST.

The 20-year-old Japanese player is ranked 18th in the world – 104 places higher than Boulter – and won her first WTA title at Indian Wells earlier this year.

“I don’t feel any pressure. I’m the underdog,” said Boulter.

Boulter played with fellow Briton Katie Swan in the doubles on Wednesday, hours after 19-year-old Swan lost 6-0 6-3 in her second-round singles match.

Asked what advice she would give her friend, Swan said: “Well, it would help if you don’t lose the first set 6-0. That would be a good start!”

Former Wimbledon runner-up Milos Raonic had to work hard before reaching the third round of the men’s singles.

The Canadian 13th seed won three tie-breaks to beat Australian John Millman 7-6 (7-4) 7-6 (7-4) 7-6 (7-4).

Raonic, 27, was tested by world number 56 Millman, but showed more consistency in the tie-breaks.

Raonic, who lost the 2016 final to Britain’s Andy Murray, will play Austrian qualifier Dennis Novak for a place in the last 16.

Novak beat 16th seed Lucas Pouille of France 6-4 6-2 6-7 (8-10) 3-6 6-2 to reach the third round of a Grand Slam for the first time.

Also through is American 11th seed Sam Querrey, who defeated Ukraine’s Sergiy Stakhovsky 7-6 (7-4) 6-3 6-3.

France’s Gael Monfils recovered from losing the opening set to beat Italy’s Paolo Lorenzi 3-6 6-3 7-6 (7-5) 7-6 (7-3), thrilling the crowd with some spectacular shots.

Third seed Marin Cilic, eighth seed Kevin Anderson and Stan Wawrinka were among those whose matches were suspended after showers late on Wednesday.

Cilic leads Guido Pello by two sets to love but Pello is 4-3 up with a break in the third, while Anderson is two sets to one up on Italy’s Andreas Seppi.

Swiss Wawrinka, now ranked 224 in the world after injury problems, lost the first set to Seppi’s compatriot Thomas Fabbiano on a tie-break, but took the second and leads 6-5 in the third.

Former world number one Victoria Azarenka admits to the odd spell of ‘baby brain’ but one thing she is clear about is the need for more childcare at tennis tournaments.

All four matches on Centre Court at Wimbledon on Wednesday featured parents – and three of them were mums: Serena Williams, Azarenka and Tatjana Maria.

Wimbledon provides a creche for the increasing numbers of tennis players with children and Azarenka wants other tournaments to follow suit.

“It really just happened just two years ago that it became a necessity,” the Belarusian told BBC Sport, referring to the fact the since her and Williams’ high-profile pregnancies the topic has become much talked about.

“Right now it is going to have to be a definite addition to the tournaments.”

Azarenka, 28, lost her singles match to Karolina Pliskova 6-3 6-3 but is competing in the mixed doubles alongside Britain’s Jamie Murray.

• Williams through to third round
• Federer eases into next round

‘Baby brain’ & training – what is it like being a mum on tour?

Azarenka, who had her son Leo in December 2016, says she fits her training in around his naps and thinks that as he gets older he will be able to come to more practice sessions with her.

She says she does not try to win “for him” and is good at just concentrating on her job on the tennis court because she knows he is in good hands with grandma.

“I want to be a good role model for my son, I think if I start focusing on winning or losing for someone it is a little bit distracting,” said Azarenka, who won the Australian Open in 2012 and 2013.

Defending champion Roger Federer was in show-stopping form on Wednesday as hoards of ‘Fed Fans’ flocked to Centre Court to watch the number one seed.

Williams sisters Serena and Venus, 2016 runner-up Milos Raonic and Australian Open champion Caroline Wozniacki were also in action, while Katie Swan was a lone raider when it came to the British challenge.

Here are six things from Wimbledon today…

• Second seed Wozniacki out to Makarova
• Williams sisters into third round
• Federer eases into next round

More shocks on day three

The top seeds in the women’s draw continued to tumble as Australian Open champion Caroline Wozniacki became the biggest name to exit the championships so far.

The Dane fought back from 5-1 down in the final set and saved four match points, before eventually succumbing 6-4 1-6 7-5 to Russian world number 35 Ekaterina Makarova.

The 27-year-old second seed was also plagued by a barrage of flying ants during Wednesday’s match on Court One, and needed insect repellent to get rid of them.

Wozniacki’s exit means only world number one Simona Halep, defending champion Garbine Muguruza and seventh seed Karolina Pliskova remain from the top eight in the women’s draw.

Czech Pliskova overcame two-time Australian Open winner Victoria Azarenka earlier on Wednesday to reach the third round at Wimbledon for the first time.

‘Near-perfect’ Fed eases through

The Federer faithful were out in force as the eight-time champion extended his Wimbledon winning streak to 26 successive sets with victory over Slovakia’s Lukas Lacko.

They were treated to the Swiss’ full repertoire, with Federer saying after his victory that playing the percentage shots too much “becomes boring”.

“I like to mix it up,” added the 36-year-old. “Not wasting too much energy is always nice.”

Federer did not face a single break point, hitting 48 winners, dropping only nine points on his serve all match and winning 35 points in a row on serve in the final set.

He also hammered down 16 aces on his way to winning 93% of his first-service points.

Former Wimbledon semi-finalist Tim Henman called it “a near-perfect performance” from the 20-time Grand Slam champion.

“When you glance at the numbers, the ones that really stand out for me are 48 winners and 11 unforced errors,” added the BBC Sport analyst.

“To be playing that aggressively, hitting the ball that cleanly, and making so few mistakes, it does bode well for his progression in the tournament.”

Williams sisters gather momentum

Serena Williams continued her Wimbledon return as she demolished Bulgarian qualifier Viktoriya Tomova in little over an hour, and then said she is “going in the right direction”.

That direction is into the third round without dropping a set, although the 25th seed is yet to be truly tested, despite a trickier first-round encounter against Arantxa Rus.

“It was better than the first-round match, so I’m happy to be going in the right direction,” said Serena, who missed last year’s tournament while on a maternity break.

“I’m not there yet but expect to get there not only for Wimbledon, but for tournaments in the future.”

Three-time Wimbledon singles champion John McEnroe said it was a chance for the seven-time winner to “kick the rust off a little”, while former world number one Kim Clijsters said the American is a contender for the title.

“She’s improved tremendously,” said Clijsters. “I thought she had to improve a lot to be a contender after the first game, and after what we saw today, she is a contender.”

Sister Venus, a five-time champion, lost the first set but fought back to beat Romanian qualifier Alexandra Dulgheru 4-6 6-0 6-1.

Football fever builds in SW19

Kyle Edmund, Roger Federer, Gael Monfils, even American Madison Keys weighed in on the World Cup debate enveloping Wimbledon at the minute.

Keys said she watched England’s last-16 penalty shootout win over Colombia on Tuesday with the injured Laura Robson, and has now backed the Three Lions to win the tournament.

“She was singing the ‘it’s coming home’ song constantly for two-and-a-half hours,” said Keys.

“I was actually into it at the end. Now I’m cheering for England.”

England meet Sweden in the quarter-finals on Saturday, a game that could potentially clash with Edmund’s fourth-round match, should the British number one make it.

It also means a grudge showdown between Edmund and his Swedish coach Fredrik Rosengren.

Sweden knocked out Switzerland to set up that England tie, and Federer turned manager to give the Swiss team some advice.

“I felt it’s an opportunity missed,” he said. “We had our chance against Sweden. In the end, they were maybe a little bit better. We didn’t create enough chances.”

Frenchman Monfils says World Cup fever has hit the locker room, and he even made time to watch England’s win in a pub.

“Actually, I watched the shootout,” he said. “I was in the restaurant and saw on the phone it was the shootout, and I saw a pub, so I just went in and watched it.

“Unbelievable. Crazy, crazy! I can’t describe it. I was scared to have my phone. It was jumping, screaming. Everything. Beers, everything. It was great.”

Flies and rain disrupt play

After two and a half days of blistering sunshine at Wimbledon, there was rain on day three.

That meant the Centre Court roof was (briefly) used for the first time at these Championships while some matches scheduled for the outside courts were delayed until Thursday.

The rain came after a swarm of insects had caused disruption earlier in the day, with Caroline Wozniacki among the players asking for insect spray.

Raon-ouch!

Canadian Milos Raonic cranked up the fastest serve of the tournament with a 147mph zinger as he downed John Millman in the second round.

He also sent down 34 aces, one of which thundered into a ball boy, while a ball girl also felt the force of another Raonic rocket.

“You don’t feel good when that happens,” said the 2016 runner-up.

“Normally by the first reaction of the kid, you can tell how they are, if it hurts. The boy I think was OK but I hit a girl a little lower in the abdomen.

“I think she probably took a little bit more of a grunt than he did. I hope she’s doing OK.”

Australian Open champion Caroline Wozniacki became the biggest name to exit the Wimbledon women’s singles as she lost in the second round.

The 27-year-old, seeded second, was beaten 6-4 1-6 7-5 by Russian world number 35 Ekaterina Makarova.

The Dane’s defeat means five of the top eight women’s seeds have exited the competition before the third round.

Wozniacki, who won at Eastbourne last week, has never been past the fourth round in 12 visits to SW19.

She was plagued by flying ants during the match on Court One and needed insect repellent to get rid of them.

• Comfortable win for Federer
• Pliskova into third round for the first time
• GB wildcard Swan goes out

“I did everything I could. It’s frustrating because I feel like I could have gone and done something really great here,” Wozniacki said.

“I can’t even be mad at myself because I played up to the level that I can.

“She played above her level and really raised it and got a little lucky.

“I would be very surprised if you saw her go far. But with someone playing like this today, I really did what I could. It just wasn’t enough.”

Makarova, who won last year’s women’s doubles title with compatriot Elena Vesnina, led 5-1 in the deciding set and had four match points on her own serve at 5-3.

Wozniacki saved all four to level it up at 5-5, but Makarova, 30, regrouped superbly, holding serve to make it 6-5 and put the pressure back her on her opponent.

This time there was no response from Wozniacki as Makarova set up a meeting with Czech player Lucie Safarova.

“I am so happy I got calm at 5-5 and did my work again,” said Makarova, who reached the quarter-finals in 2014.

“When it was 5-5 I started thinking about those match points on my serve at 40-0, but I told myself, ‘No, you are not going to lose this match’. I forgot it and started over.”
