PARIS (AFP) - Defending champion Ana Ivanovic breezed into the last 16 at the French Open on Friday but Portuguese teen prodigy Michelle Larcher de Brito saw her dream of becoming the youngest ever women's winner bite the dust. The Serbian, wearing strapping on her troublesome right knee but showing no signs that the injury was hampering her, had too much power and all-round skill for Iveta Benesova of the Czech Republic winning 6-0, 6-2. That put her into a matchup against either ninth seed Victoria Azarenka of Belarus or Carla Suarez Navarro of Spain with a place in the quarter-finals going to the winner. The 21-year-old Belgrade beauty, who reached the world No.1 spot after her win here last year but who has struggled for form and fitness since then, said she had played one of her best matches of the year. "I feel fit and ready to handle any kind of opponent," she said. "My game is coming back and I feel more comfortable. I really missed competition last month. "These kind of matches help for the tough matches ahead in the second week." Larcher de Brito, at 16 years and four months the youngest player left in the women's draw, went down 7-6 (7/3), 6-2 to France's Aravane Rezai in a bad-tempered clash that saw the players trading barbs over the Portuguese player's ear-splitting on-court vocals. Rezai on several occasions complained to the umpire that the high-pitched screams that accompanied her opponent's shot-making were putting her off with Larcher de Brito insisting she was doing nothing wrong. De Brito, the latest player to emerge from Nick Bollitieri's famed Florida academy, clawed her way back from a break down to force a tie-break against Rezai, but double faults let her down in that. In the second set she quickly fell behind as her service game wobbled again and despite saving three match points at 1-5 down, she could do nothing to prevent 22-year-old Rezai reaching the fourth round for the first time in five attempts. A grudging handshake at the net saw Larcher de Brito jeered off by the Centre Court crowd. Rezai, one of only two Frenchwomen left after the early defeats of Amelie Mauresmo, Marion Bartoli and Alize Cornet, will meet top seed Dinara Safina in the fourth round if the Russian defeats compatriot Anastasia Pavlyuchenkova later in the day. Also in action later Friday is Maria Sharapova, looking to extend her comeback run against Yaroslava Shvedova of Kazakhstan, and third seed Venus Williams who goes up against Agnes Szavay of Hungary.
