PARIS (AFP) - Australian Open champion Victoria Azarenka reached the French Open second round on Wednesday but Agnieszka Radwanska's hopes of playing little sister Urszula for a place in the last 16 were dashed.
The Belarusian clinched a 6-1, 6-4 win over Elena Vesnina - her fifth win in five matches against the experienced Russian - and will next face German 19-year-old Annika Beck, the 2012 junior champion, for a place in the third round.
"It felt good to be on the court after getting cancelled yesterday," said Azarenka. "It was a good win as Elena is a really tough opponent."
Polish fourth seed Agnieszka Radwanksa, who has never advanced beyond the fourth round, eased past Mallory Burdette of the United States 6-3, 6-2.
She had been scheduled to tackle her sister for a place in the last 16, but Urszula, who put out Venus Williams in the first round, crashed out 6-3, 6-3 to German qualifier Dinah Pfizenmaier, the world No. 127.
Spanish men's fourth seed David Ferrer, a semi-finalist in 2012, made the third round, beating compatriot Albert Montanes, 6-2, 6-1, 6-3.
Sixth seed Jo-Wilfried Tsonga, France's best hope of a first men's champion in Paris for 30 years, defeated Finnish veteran Jarkko Nieminen, 7-6 (8-6), 6-4, 6-3.
Tsonga, a quarter-finalist last year when he squandered four match points against Novak Djokovic, next faces either compatriot Jeremy Chardy or Roberta Bautista Agut of Spain.
Croatian 10th seed Marin Cilic ended the hopes of Australian teenager Nick Kyrgios, the world No. 262, by winning 6-4, 6-2, 6-2.
