Paris, France (SportsNetwork.com) - Two-time Wimbledon champion Petra Kvitova advanced to the fourth round at the French Open with a 6-3, 6-2 win over 30th- seeded Romanian Irina-Camelia Begu on Saturday.
Kvitova, a semifinalist at Roland Garros in 2012, committed only nine unforced errors and did not face a break point.
"I think it was, for sure, the best match I've played here so far. I'm really glad for it," said Kvitova, who needed three sets to win each of her first two matches.
Up next for the fourth-seeded Czech will be Timea Bacsinszky of Switzerland.
Bacsinszky, seeded 23rd, beat American Madison Keys 6-4, 6-2 to reach the round of 16 at a Grand Slam for the first time in her career.
The 16th-seeded Keys had advanced to the semifinals at the Australian Open in January.
Fellow American Irina Falconi also lost her third-round match. She was beaten by German Julia Goerges 6-4, 6-1.
In other third-round play, former French Open finalist Sara Errani gained a measure of revenge against 10th-seeded German Andrea Petkovic with a 6-3, 6-3 win. The 17th-seeded Italian was ousted by Petkovic in the quarterfinals at Roland Garros last year.
Errani's countrywoman, Francesca Schiavone, failed to join her in the fourth round. The 2010 French Open champion lost 7-5, 6-4 to unseeded Romanian Andreea Mitu.
Ranked 100th in the world, Mitu had never won a match at a major tournament before this week.
Belgian Alison Van Uytvanck advanced with a 6-4, 6-1 win over France's Kristina Mladenovic.
