(CNN) -- Maria Sharapova's comeback from injury continued with a comfortable victory over Darya Kustova of Belarus in the second round of the Warsaw Open on Wednesday.
Maria Sharapova is hoping to prove her fitness ahead of the French Open in Paris starting on Sunday.
The Russian -- who has been out for 10 months with a long-term shoulder injury, which has meant her world ranking has plummeted to 126 -- cruised to a 6-2 6-0 victory in less than an hour.
Fifth seed Italian Sara Errani suffered worse fortunes, however, crashing out 6-4 6-3 to Alexandra Dulgheru, and third seed Jie Zheng was thrashed 6-0 6-4 by Klara Zakaopalova.
Briton Anne Koethavong battled to a 3-6 6-3 6-1 win over American Jill Craybas to set up a third-round clash with Ioana Raluca Olaru, who beat Julia Goerges 6-3 0-6 7-6.
Alona Bondarenko dispatched Marta Domachowska of Poland to meet Sharapova in the next round, but her sister Kateryna Bondarenko lost 6-4 7-6 to Galina Voskoboeva. Meanwhile, Daniela Hantuchova downed Urszula Radwanska 6-3 6-1.
