World number four Roger Federer and defending champion Serena Williams have cruised to the second round of the French Open, while India's numero uno player Somdev Devvarman has crashed out of the Roland Garros on Sunday.

Federer registered a comfortable victory over wildcard Lukas Lacko in straight sets. The Swiss maestro outclassed his Serbian opponent 6-2, 6-4, 6-2 in just 84 minutes. The 17-time Grand Slam winner hit 40 winners and registered his 59th win at the French capital.

The 32-year-old Swiss will not face either Gastao Elias or Diego Sebastian Schwartzman in the second round. "It was important for me to attack and stay aggressive," said Federer. "I also served well."

Defending champion Serena started her title defence with a convincing 6-2, 6-1 victory over Alize Lim in the opening encounter. The 32-year-old Serena, however, looked rusty in her first match as she made 24 unforced errors.

Serena improved her record in the French Open to 54-1 as her only loss came in 2012, when she lost to 111th-ranked Virginie Razzano.

Indian tennis ace Somdev lost his first round encounter to Aleksander Nedovyesov in a hard-fought four-set encounter. The highest-ranked Indian went down 7-5, 3-6, 6-7(4), 3-6 in three hours and 13 minutes.

Somdev's woeful run in the French Open continued, as he is yet to go beyond the second round at Roland Garros. Devvarman started the match strongly by winning the first set, but Nedovyesov rallied back to clinch the next three sets to sent the Indian packing.

The third-seeded Agnieszka Radwanska outclassed her Chinese opponent Zhang Shuai 6-3, 6-0 in the first round. Radwanska capitalised on 24 unforced errors made by Zhang and clinched the match in just 21 minutes.

Last year's quarterfinalist Radwanska will face either Czech Republic's Karolina Pliskova or French wildcard Mathilde Johansson in the last-32 clash.

Canadian Milos Raonic opened his campaign against Australian prodigy Nick Kyrgios with a straight set victory. World number nine Raonic survived a second set tiebreaker to clinch the match 6-3 7-6(1) 6-3 in exactly two hours.

Raonic made full use of his big first serve and racked up 27 aces against the Australian teenager and scored 90 percent points on his first serve.

"I felt very good. I was able to do the things I wanted to do. Sort of the first round you go in not knowing exactly how things are going to play out, and I was able to, when it mattered, put forward the right attitude and the right level of tennis," Raonic said.

Meanwhile, Frenchman Jo-Winfried Tsonga kicked off his French Open campaign by defeating the fellow countryman Edouard Roger-Vasselin 7-6(7-4) 7-5 6-2.
