Wimbledon champion Petra Kvitova reached the third round of the French Open by beating Urszula Radwanska of Poland 6-1, 6-3 Thursday.
The fourth-seeded Czech was never really tested on Court Suzanne Lenglen, saving all three break points she faced.
Kvitova secured her first Grand Slam title at Wimbledon last year, and then won the WTA Championships. Although she has yet to win a title in 2012, she is seeded fourth in Paris and is expected to go deep into the tournament.
Radwanska is the younger sister of third-seeded Agnieszka Radwanska, who reached the third round on Wednesday by beating seven-time Grand Slam champion Venus Williams.
Later Thursday, second-seeded Maria Sharapova was to face Ayumi Morita of Japan, and defending champion Li Na was to play Stephanie Foretz Gacon of France. Also, defending men's champion Rafael Nadal was scheduled to play Denis Istomin of Uzbekistan. Nadal is looking for a record-breaking seventh title at Roland Garros.
For Roger Federer, setting records on the tennis court is becoming ho-hum.
The perks that come with them, like dining with Queen Elizabeth II, are the things to really remember.
"Yes, I have had lunch next to the queen — with the queen, basically," Federer said. "Big honor, obviously ... Thank God, she came."
Federer beat Adrian Ungur of Romania 6-3, 6-2, 6-7 (6), 6-3 in the second round Tuesday. With the win, the 16-time Grand Slam champion broke a record he shared with Jimmy Connors for most career victories at major tournaments in the Open era, which began in 1968. He is now 234-35 in tennis' top four tournaments, an .870 winning percentage.
But he was less than his dominant self, wasting two match points in the third set before losing the tiebreaker.
"Instead of being aggressive, I let him show me what he could do," Federer said. "He played two beautiful shots, and then I started not playing very well."
Novak Djokovic also advanced to the third round, as did top-seeded Victoria Azarenka of Belarus.
