Kvitova safely through in Paris

Czech fourth seed Petra Kvitova strolled into the French Open third round with a comprehensive 6-1 6-3 win over Pole Urszula Radwanska.

Kvitova, who had only dropped three games in her opening round, was never threatened by the world number 79, hitting 30 winners in a one-sided match on Court Suzanne Lenglen.

The Wimbledon champion ended Radwanska's misery after 70 minutes on her second match point when the Pole sent a backhand long.

Kvitova, heading towards a possible quarter-final clash with defending champion Li Na of China, will next face Frenchwoman Claire Feuerstein or Russian Nina Bratchikova.

In other women's singles second-round match, Anastasia Pavlyuchenkova from Russia beat Hungarian Melinda Czink 4-6, 6-3, 6-3; Angelique Kerber (Germany) beat Olga Govortsova (Belarus) 6-3, 6-2; Klara Zakopalova (Czech Republic) beat Maria Kirilenko (Russia) 6-4, 3-6, 6-3.
