Serena Williams boosted her chances of winning an eighth Wimbledon and 24th Grand Slam by making the fourth round at the All England Club on Friday as big sister Venus fell victim to the curse of the seeds.

Only two of the top 10 seeds remain in the women’s draw – number one Simona Halep, who plays her third round match on Saturday, and seventh seed Karolina Pliskova who came back from 1-4 down in the second set to defeat Mihaela Buzarnescu 3-6, 7-6 (7/3), 6-1.

While the women’s draw was being blown wide open, it was business as usual for defending men’s champion Roger Federer who enjoyed a 6-3, 7-5, 6-2 win over Germany’s Jan-Lennard Struff.

The big stories

Venus beaten by Bertens

Venus Williams blamed bad luck for her shock Wimbledon exit as the five-time champion became the latest star to crash out in a 6-2, 6-7 (5/7), 8-6 defeat against Kiki Bertens.

After reaching the final last year and the semi-finals in 2016, Venus was expected to mount another strong challenge for the Wimbledon title. But instead the 38-year-old was worn down by Dutch 20th seed Bertens in a dramatic third round clash lasting two hours and 40 minutes in sweltering heat on Court One.

Serena sweeps Mladenovic aside as draw opens up

Seven-time champion Serena Williams reached the Wimbledon fourth round with a 7-5, 7-6 (7/2) win over France’s Kristina Mladenovic.

Williams, seeded 25 and chasing a 24th Grand Slam title, will face Russian qualifier Evgeniya Rodina for a place in the quarter-finals. The match on Monday will also be a tussle between two of the tour’s mothers.

Qualifier downs Keys

Also exiting was 10th seed Madison Keys, who had made at least the quarter-finals of her last three majors. The American lost 7-5, 5-7, 6-4 to Rodina, ranked 120th in the world.

“I have played the quallies and three matches this week which were all three sets,” said 29-year-old Rodina. “She hits the ball so hard. I am a little surprised that I won, I was a little bit lucky.”

Federer breezes past German comeback specialist

Defending champion Roger Federer eased into the Wimbledon fourth round with a 6-3, 7-5, 6-2 win over Germany’s Jan-Lennard Struff.

Federer took his consecutive sets won at Wimbledon to 29 in what was his 200th career grass court match. The eight-time champion will face French 22nd seed Adrian Mannarino on Monday for a place in the quarter-finals.

Zverev beats Fritz in five

German fourth seed Alexander Zverev made the third round, seeing off Taylor Fritz of the United States 6-4, 5-7, 6-7 (0/7), 6-1, 6-2 and faces Latvian qualifier Ernests Gulbis for a spot in the last 16.

Zverev had trailed two sets to one when his tie with Fritz was halted due to darkness on Thursday. But the 21-year-old raced away with the last two sets in Friday’s bright sunshine.
