There were more shock exits in the women’s singles draw on day five at Wimbledon.

But elsewhere Nick Kyrgios still grabbed the headlines, Roger Federer and Serena Williams continued to dominate on Centre Court and there was a three-day, five-hour, five-set thriller involving two Britons in the men’s doubles.

Here are five things from Wimbledon day five.

Federer sweeps aside Struff

Top seed Federer was flawless yet again.

Whatever Germany’s Jan-Lennard Struff threw at him, he had an answer and it was in typically emphatic fashion that he made it through to round four with a 6-3 7-5 6-2 win on Centre Court.

The defending champion needed just one hour and 34 minutes to win – a much easier ride than his next opponent Adrian Mannarino, who had to come from behind in the fifth set to make it through to the last 16.

The Swiss has still not even dropped a set at Wimbledon this year – extending his winning streak to 29 in a row – and he looks full of energy.

Venus the latest star to fall

Five-time Wimbledon champion Venus Williams was the biggest casualty on another tough day for the seeded players.

Eight of the top 10 seeds in the women’s singles have now failed to make it through to the last 16.

“Some of it is players not having a plan B, or plan C,” former Australian Open semi-finalist Chanda Rubin told BBC Sport.

“You have to somehow find a way to win on those days when you are not at your best and some of the top players just haven’t been able to do that.”

• Why are so many seeds out of Wimbledon?

Ninth seed Williams, 38, was beaten 6-2 6-7 (5-7) 8-6 by 26-year-old Dutchwoman Kiki Bertens.

Williams’ fellow American Madison Keys, 23, also exited after an erratic 7-5 5-7 6-4 loss to Russian qualifier Evgeniya Rodina who is ranked 120th in the world.

Romanian Mihaela Buzarnescu fought back the tears as she lost 3-6 7-6 (7-3) 6-1 to Czech seventh seed Karolina Pliskova.

Russian Ekaterina Makarova, Germany’s Julia Goerges and Donna Vekic of Croatia all progressed.

Serena improves again in third showing

While many around her are falling, Serena Williams is only growing in stature.

She came through her first proper test against France’s Kristina Mladenovic 7-5 7-6 (7-2) despite going a break down in the first set.

The 23-time Grand Slam champions still hasn’t dropped a set and with eight of the top 10 women’s seeds now out, the road is clearing rapidly towards an eighth Wimbledon title.

“Just getting to the round of 16 twice is not bad. Hopefully I can do a little bit better,” she said. “I don’t have anything to lose. I have absolutely nothing to prove.”

Britons come out on wrong side of 42-game final set

With only one home player left in action in the singles draws, attentions turned to the doubles, where eight Britons made it through.

Jay Clarke and Cameron Norrie did not but they were involved in an epic five-hour battle on court 14 against first-round opponents Marcelo Arevalo and Hans Podlipnik-Castillo.

The match began on Wednesday and was suspended with the Britons 3-2 up in the first set because of rain. It resumed on Thursday but bad light forced another stoppage with Clarke and Norrie two sets to one up and leading 4-6 7-6 (7-5) 7-5 4-3.

Arevalo and Podlipnik-Castillo bounced back to take the fourth set 6-4 on Friday. The players tussled back and forth in the fifth and final set, before Clarke and Norrie lost it 22-20 in front of a highly entertained crowd.

It was the first time the two Britons were playing together at a Grand Slam after they were handed a wildcard to compete in the men’s doubles – and it was certainly a match to remember.

Kyrgios at the centre of it all again

Kyrgios has already caused controversy at this year’s Wimbledon championships and he did so again on Friday without even lifting a racquet.

After getting caught up in two exchanges with umpire James Keothavong on Thursday, receiving a code violation for inappropriate language, the Australian 15th seed has now caused further sparks with his social media use.

He went on Instagram to respond to criticism from 2013 champion Marion Bartoli after she said he was “childish” and lacks “work ethic” on Radio 5 live on Thursday.

Kyrgios asked Bartoli to “stop assuming you know what’s best for others” in a lengthy post which he signed off with the words: “we don’t care what you have to say”.

He faces Japan’s Kei Nishikori in the third match on Court One on Saturday.

Fourth seed Alexander Zverev beat Taylor Fritz 6-4 5-7 6-7 6-1 6-2 in the second round of Wimbledon after a suspension in play overnight.

Play was halted because of bad light on Thursday with world number three Zverev two sets to one behind on Court One.

But the German bounced back in emphatic style to win the following two sets as Fritz struggled to regain his form.

The American, ranked 68th, held on early in the fifth but Zverev then broke away to reach round three.

The 21-year-old is yet to win a Grand Slam but picked up his fourth ATP title in New York in February.

“Unfortunately we are out in the football,” he told BBC Sport, referring to Germany being eliminated form the World Cup in Russia at the group stage.

“But hopefully I can win a few more matches here and the crowd can have something to cheer about.”

In the third round, South African eighth seed Kevin Anderson, who reached the 2017 US Open final, beat German fifth seed Philipp Kohlschreiber 6-3 7-5 7-5.

Defending champion Garbine Muguruza became the sixth top-eight women’s seed to exit Wimbledon as she lost to Alison van Uytvanck in the second round.

Belgian world number 47 Van Uytvanck demonstrated skill and power to beat the third seed 5-7 6-2 6-1.

The Spaniard suffered the earliest defeat of a defending women’s champion at the All England Club since Steffi Graf lost in the first round in 1994.

“Inside I was dying, especially serving out for the match,” Van Uytvanck said.

Top seed Simona Halep beat China’s Saisai Zheng 7-5 6-0 earlier on.

Halep and seventh seed Karolina Pliskova are the only top-eight seeds remaining in the women’s draw.

It is only the second time that Van Uytvanck has gone beyond the second round at a major.

“In sets two and three I was just there mentally. I was in the zone and just hitting every ball and it was going my way,” she said.

“I would love to be in the second week for the first time at Wimbledon.”

Muguruza trailed 4-2 but won three games in a row in the opening set to lead 5-4.

Van Uytvanck fought back and Muguruza needed a second chance to serve out for the opening set.

The Belgian continued to show her fighting spirit in the second set and broke for a 4-2 advantage, with her forehand causing Muguruza all sorts of problems.

Van Uytvanck broke to make it 3-1 in the decider and showed few signs of nerves, breaking again for 5-1 before wrapping up the biggest win of her career and making it through to the third round for the first time.

She will next face Estonian 27th seed Anett Kontaveit for a place in the last 16.

Muguruza admitted it has been a tough match for both players.

“She played big, took a lot of risk and it worked for her,” she said. “I also think that my level was not where I wanted it to be. That’s also why she could develop that kind of level.

“It’s a bit sad because I wanted to really go out there. But I think she played great and she has a very good game for this surface.”

Van Uytvanck played fearlessly – analysis

Four-time Grand Slam champion and fellow Belgian Kim Clijsters: “It is a huge win. Van Uytvanck is a super nice girl. She had to deal with injuries in 2016 and worked hard to come back. For her to have this result is amazing. I am really happy for her.”

Three-time Wimbledon champion Boris Becker: “Court Two has the nickname of the graveyard because a lot of top seeds have lost on this court. The superstars are used to playing on Centre Court, Court One. Here it is a different atmosphere for both players.”

Former tour player and BBC commentator Chanda Rubin: “Van Uytvanck looked the same at 2-2 in the first set as she did at the end. You could not tell she was getting close to the biggest moment in her career. She’s been fearless and played strategically so well.”

Halep fights back to reach third round

Halep was 5-3 down in the first set against the world number 126 but once she got into her stride was a comfortable winner.

“I stopped missing and tried putting less power on the shot to make her run,” the 26-year-old told BBC Sport.

“I just have to fight for every point.”

Next up for the world number one will be Su-Wei Hsieh of Chinese Taipei.
