Two-time Wimbledon champion Petra Kvitova, 2009 French Open winner Svetlana Kuznetsova and 2014 finalist Simona Halep have all advanced to the third round at Roland Garros. Kvitova, who reached the semifinals at Roland Garros in 2012, looked more comfortable than in her first-round match. Extra precautions introduced following deadly attacks in Paris in November include an initial pat-down, bag check and scan with a metal detector before reaching Roland Garros, followed by another more thorough search at the gates. Security has also been stepped up for soccer's European Championship in 10 French cities starting next month.
