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 Lawns Tennis Club, made the reigning French Open champ work on Thursday.

Pironkova won the second set in a tiebreak 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 Hsieh 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 25th-seeded Chinese Zheng Jie, a 6-4, 6-2 winner Thursday against Canada's Aleksandra Wozniak.

Eighth-seeded Angelique Kerber of Germany posted a 7-5, 6-3 win over Russian Ekaterina Makarova and will next play 28th-seeded American Christina McHale, who recorded a 7-5, 7-5 victory over Frenchwoman Mathilde Johansson.

Another top-10 seed bit the dust this week, as Croat Mirjana Lucic swept out No. 9 Marion Bartoli 6-4, 6-3. The French Bartoli, who is the third top-10 woman to exit the draw over the first four days of the fortnight, was a surprise Wimbledon runner-up back in 2007.

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, 21st-seeded Roberta Vinci, also moved on with a 6-4, 6-3 triumph over Marina Erakovic of New Zealand.

Fourteenth-seeded former No. 1 star Ana Ivanovic bested Ukrainian Kateryna Bondarenko 6-3, 7-6 (7-3), while 20th-seeded Russian Nadia Petrova outlasted Hungarian Timea Babos, 6-4, 6-7 (3-7), 9-7 in 3 hours, 4 minutes, including a 91-minute final set, and 22nd-seeded German Julia Goerges handled Belarusian Anastasiya Yakimova 7-6 (7-3), 6-2. The Serbian Ivanovic is a former French Open champ who has yet to reach a Wimbledon quarterfinal.

Also advancing to the third round were Austrian slugger Tamira Paszek, Kazakhstan's Yaroslava Shvedova and Czech veteran Klara Zakopalova. The 2011 Wimbledon quarterfinalist Paszek, who doused former No. 1 Caroline Wozniacki on Wednesday, drilled France's Alize Cornet 6-2, 6-1.
