No stopping the Williams sisters

‘Andreescu deserved to win’ – Kerber after losing Indian Wells final

Top seed Serena Williams, 34, and her sister Venus, 36, both made it safely through to the quarter-finals of Wimbledon on Monday.

The siblings continued to defy their advancing years as they both secured straights victories in their fourth-round clashes.

Serena survived a tightly contested first set against Russian Svetlana Kuznetsova before pulling away in the second, eventually completing a 7-5, 6-0 victory.

Kuznetsova was highly competitive in the first set, twice hitting back with a break of her own after falling a break behind, but there was no coming back from Serena’s third break in the 12th game, which saw her wrap up the first set.

Having gotten her nose in front, the second set went by in the blink of an eye for Williams as Kuznetsova's challenge faltered.

The American broke three times to wrap up the set in just 20 minutes and set up a quarter-final clash with another Russian, 21st seed Anastasia Pavlyuchenkova.

"She has played really well against me in the past and beat me earlier this year so I knew I had to play well to win," Serena told BBC Sport.

"It was really tricky out there. It wasn't raining hard but was dewy and on the grass you can fall easily – then you think 'should I run or not' and it became more difficult because of that."

Eighth seed Venus, meanwhile, scored a very impressive 7-6 (7-3), 6-4 victory over 12th seed Carla Suarez Navarro in one hour and 39 minutes.

Suarez Navarro raced to a 3-0 lead in the first set courtesy of two breaks, but Venus regained one of those lost breaks in game four and another in game 10 before getting the better of her opponent in the tie-break.

She then claimed two breaks to Suarez Navarro's one in the second set to wrap up a much deserved victory.

Also advancing to the quarter-finals later in the day were Russian Elena Vesnina and Russian-born Kazakhstani Yaroslava Shvedova.

Vesnina beat her compatriot Ekaterina Makarova 7-5, 1-6, 9-7, while Shvedova defeated Lucie Safarova of Czech Republic 6-2, 6-4.
