Script:

Rome Open semi-finalist Ana Ivanovic lost in straight sets against world number 24 Lucie Šafářová in the Roland Garros third round on Saturday.

Ivanovic hit this wild forehand to lose 6-3 6-3.

Kuznetsova enjoyed causing an upset of her own, when she knocked out world number six Petra Kvitová.

The Russian came back from a set down and held her nerve in this long rally to win 6-7 6-1 9-7. Next up for Kuznetsova is another Czech left-hander, Lucie Šafářová.

There was no such scare for Romanian Simona Halep, who enjoyed a straight sets defeat of María Teresa Torró Flor.

Halep hit this towering forehand winner straight off the Spaniard's serve to record a 6-3 6-0 victory in Paris.

Sixth-seed Jelena Janković eased into the last 16 with a comfortable victory against Romanian Sorana Cîrstea.

The 2010 Roland Garros semi-finalist's 6-1 6-2 win earns her a fourth round match against Sara Errani.

The Italian made it through to the next round after an equally hassle-free contest against Israeli Julia Glushko.

Errani's 6-0 6-1 victory keeps alive her hopes of beating her previous best run in the French capital, when she finished runner-up two years ago.
