Tennis legends Roger Federer and Serena Williams cruised into the quarter-finals of Wimbledon today as the second week began with a busy day of last 16 matches.

The Swiss and American duo, who have collectively won 13 singles titles on the grass of SW19, each continued their pursuit of a first Grand Slam title of the year with a straight-sets victory.

Defending champion Williams beat Russian rival Svetlana Kuznetsova in a topsy-turvy contest which was changed by the closing of the Centre Court towards the end of the first set.

Until that point, Kuznetsova had been on top, breaking twice to set up a chance to serve-out for the first set.

But her 34-year-old rival was completely dominant thereafter as the indoor conditions favoured the American's huge serve.

Williams duly won eight successive games to power to a 7-5, 6-0 victory.

Seven-time champion Federer was even more dominant as he reached a 14th Wimbledon quarter-final with a 6-2, 6-3, 7-5 thrashing of US rival Steve Johnson.

It appeared an ominous return towards his best form as he seeks to take advantage of the absence of world number one Novak Djokovic after his shock defeat last week.

World number two Andy Murray now appears his biggest threat, as the home player cruised past Australia's Nick Kyrgios 7-5, 6-1, 6-4.

Djokovic's vanquisher, Sam Querrey, continued his winning run with a 6-4. 7-6. 6-4 win over France's Nicolas Mahut.

Canada's sixth seed Milos Raonic produced arguably the performance of the day, recovering from two sets down to beat 11th-seeded Belgian opponent, David Goffin, 4-6, 3-6, 6-4, 6-4, 6-4.

Two other top eight seeds exited the competition, both due to injury-induced withdrawals.

Seventh seed lasted just six games before pulling-out against fellow Frenchman Jo-Wilfried Tsonga, while Japan's fifth seed Kei Nishikori pulled-out while trailing 6-1, 5-1 to Croat Marin Cilic.

A second Frenchman also made it through in the form of Lucas Pouille, who won 10-8 in a fifth set thriller over Australia's Bernard Tomic.

The shock result of the day in the women's draw came when 19th seed Dominika Cibulková shocked Polish third seed Agnieszka Radwanska, 6-3, 5-7, 9-7.

Five-time champion Venus Williams also progressed with a 7-6, 6-4 win over Spain's Carla Suarez Navarro.
