Tamarine Tanasugarn, the veteran Thai player, is overjoyed by her best -ever performance at Wimbledon. A serious challenge lies ahead in the quarter-finals, however, and her name is Venus Williams.

Agnieszka Radwanska hopes to do better than younger sister Urszula when she takes on Serena Williams in the quarter-finals. It follows her triumphant three set defeat of number four seed Svetlana Kuznetsova this afternoon.

Feliciano Lopez recovered from three match points down to dispose of tenth seeded Marcos Baghdatis in an edge-of-the-seat 5-7, 6-2, 3-6, 7-6 (4), 8-6 encounter.

Jelena Jankovic was not a happy woman after her defeat by Tamarine Tanasugarn. As well as being pained by injury, she also revealed why she thought a midday match on Court 18 was a case of “wrong place, wrong time”.

Stop the press. Hold the front page. Roger Federer – the coolest customer in London SW19 since Bjorn Borg was patrolling the Wimbledon lawns – has admitted to suffering from pre-match nerves.

Roger Federer did not produce a vintage performance in his straight sets defeat of Lleyton Hewitt but the Swiss was always in charge against a player unable to perform at his terrier-like best due to a hip injury

Venus Williams said she had no qualms about playing on Court 2, despite losing there in 2006. “I’m here for the tennis and will play wherever I am down to play. I just love playing here. It’s just that simple.”

Roger Federer won the battle of the champions with a solidly impressive 7-6 (9-7) 6-2 6-4 victory over Australia’s Lleyton Hewitt, the only man other than him in the draw who has lifted the men’s singles crown.

No 21 seed Nadia Petrova ended the run of Alla Kudryavtseva, conqueror of Maria Sharapova, in straight sets. The 26-year-old gave her 154-ranked compatriot a lesson in grass court tennis to go through to the quarter-finals

The Williams bandwagon rolls on. After Venus coasted to a straight sets victory over Alisa Kleybanova, her sister Serena followed her on to No. 2 court and made light work of fellow American Bethanie Mattek, brushing her aside 6-3, 6-3.

Second seed Jelena Jankovic was given a short, sharp shock as she was knocked out in the fourth round by unseeded Wimbledon veteran Tamarine Tanasugarn of Thailand.

Four-time champion Venus Williams fought off a late challenge from Russian teenager Alisa Kleybanova to reach her ninth Wimbledon quarter-final, winning 6-3, 6-4 to set up a meeting with Tamarine Tanasugarn.

China’s big hope for Olympic doubles gold Jie Zheng continued her golden run in the Wimbledon ladies’ singles by beating her third seed inside a week, Hungary’s Agnes Szavay, to move through to the last eight.

Hungary’s Agnes Szavay, 19, has had a meteoric rise through the women’s ranks but has struggled through the first few rounds at WImbledon and faces a tough test against Zheng Jie, conqueror of Ana Ivanovic, in the fourth round

The “other Swiss player”, who faces Marat Safin on Monday, is quite content to stay in Roger Federer’s shadow as he quietly steals up the rankings and establishes himself as a genuine top 10 player.
