Wimbledon: Williams sisters both knocked out in last 16

Venus and Serena Williams have both tumbled out of the Wimbledon tennis finals in London's SW19 famous courts. Venus, who is a seven-time Grand Slam title winner in the singles and Serena, who has won thirteen singles titles are both out.

Serena, who won the title at Wimbledon last year, was stunned by a subliminal performance by French star Marion Bartoli who battled through to a straight sets victory 6-3 7-6 (8-6). She will now play Sabine Lisicki in the quarter-finals. To make matters worse for Serena - she spent almost a year out with injury - she has fallen to a world ranking low of 180th, reports the BBC. Bartoli was outstanding in the Wimbledon 2007 semi-final against Justine Henin where she eventually lost in the final to Venus Williams. Bartoli said after the game: "I'm extremely happy about what I did today, especially against Serena, who's extremely tough to beat, It was great performance but tomorrow is another day and I can't think too much ahead." Venus meanwhile was beaten by Tsvetana Kirilova Pironkova, a Bulgarian rising star who is only ranked number 33 in the ATP rankings. Pironkova beat Venus Williams 6-2 6-3 in a match played in searing south London heat of around 34c (93f) Earlier in the Monday play, World number one Caroline Wozniacki crashed out as Dominika Cibulkova overcame the 20-year-old in three sets to make it through to the quarter-finals. On Friday Serena Williams had complained about being moved to Court Two which holds holds 4,063 spectators – 7,330 fewer than Court One and 10,916 fewer than Centre Court. There is just a week left in the Wimbledon finals as the competition reaches the quarter-final stages now.
