Wimbledon, England (Sports Network) - Maria Sharapova and Serena Williams were among the second-round winners Thursday at Wimbledon.

The top-seeded Sharapova finished off Bulgaria's Tsvetana Pironkova in a match that was suspended on Wednesday because of darkness, while Williams cruised past Hungary's Melinda Czink.

Sharapova, the 2004 Wimbledon champion, had won the first set and was ahead in the second when play was halted Wednesday. Pironkova, a semifinalist two years ago and a quarterfinalist last year at the All England Club, made the reigning French Open champ work on Thursday.

Pironkova won the second set in a tiebreaker before Sharapova dominated the third and advanced with a 7-6 (7-3), 6-7 (3-7), 6-0 triumph. The top-ranked Russian will next face Taiwan's Su-Wei Hseih in the third round.

The sixth-seeded Williams, meanwhile, had little drama in a 6-1, 6-4 pounding of Czink and the four-time Wimbledon champ will next take on China's Jie Zheng, a 6-4, 6-2 winner Thursday against Canada's Aleksandra Wozniak.

Eighth-seeded Angelique Kerber of Germany finished off a 7-5, 6-3 win over Russian Ekaterina Makarova and will next play American Christina McHale, who also completed a 7-5, 7-5 victory over Frenchwoman Mathilde Johansson.

Italy's Sara Errani, the 10th seed and French Open runner-up, cruised to a 6-1, 6-1 rout of Britain's Anne Keothavong, while fellow Italian Robert Vinci also moved on with a 6-4, 6-3 triumph over Marina Erakovic of New Zealand.

Defending champion Petra Kvitova is also slated for action later Thursday against Britain's Elena Baltacha, while second-seeded Victoria Azarenka will meet Switzerland's Romina Oprandi.
