Just hours after her younger sister Serena unexpectedly exited Roland Garros 2008, eighth seed Venus Williams was shocked by Italian 26th seed Flavia Pennetta who defeated her 7-5 6-3.

In this third round match, the 2002 French Open finalist Williams lost serve three times and committed 29 unforced errors.

If you are familiar with at least some of Bethanie Mattek’s previous outfits, you are probably just as excited as me to take a look at her wardrobe at Roland Garros. Enjoy as the world No.106, famous for her sense of style, shows you her clothes.

Reminder: Mattek today exited the 2008 French Open, but she played three sets against top seed Maria Sharapova in their second round match.

Top seed Maria Sharapova had to play another unexpected three-setter at the 2008 French Open to beat world No.106 Bethanie Mattek and advance to the third round.

Sharapova, who started her Roland Garros campaign with a scrappy performance against Evgeniya Rodina, finally beat Mattek in two hours and three minutes. Final score was 6-2 3-6 6-2.

Slovenian Katarina Srebotnik scored the biggest victory of her career and the biggest upset of the 2008 Roland Garros defeating eight-time Grand Slam champion Serena Williams 6-4 6-4 in the third round.

Fifth seed Williams suffered her earliest exit at the French Open since 1999. Also, the 2002 French Open winner Williams was the only former champion in this year’s draw, which now means we will have a first-time women's champion.

World No.5 Williams converted only one of eight breakpoint chances during the match, and in the second set that proportion was 0-for-6. Also, Williams failed to finish her well-constructed points, and lost 14 of 21 points at the net.

Until today, Williams was 3-0 in career meetings with Srebotnik, who is currently ranked 24th in the world. However, in their last match on clay at the Family Circle Cup in April, Srebotnik took the opening set before Serena won 4-6 6-4 6-3.

World No.6 Anna Chakvetadze became the highest seeded player to lose at Roland Garros 2008.

The sixth seed fell to Estonian Kaia Kanepi 6-4 7-6 in the second round, after dropping serve four times and losing the tie-break 7-2. Last year, Chakvetadze reached quarterfinals at the French Open.

World No.49 Kanepi will next face either Spaniard Anabel Medina Garrigues, seeded 29th, or Tsvetana Pironkova. (via Reuters, photo: Getty Images)
