Novak Djokovic and Roger Federer beat their respective opponent to cruise into the third round of the French Open on Wednesday.

Second seed Djokovic, who bids to win the French Open to complete a career Grand Slam, needed just over 90 minutes to beat Jeremy Chardy 6-1, 6-4, 6-2.

"It was another match where I had to stay mentally tough and then try to be consistent and not have many ups and downs," the Serbian player said about his game plan.

"I managed to stay solid from the baseline, and I think that forced him to make a lot of unforced errors, which definitely helped me to win in straight sets," he said.

It was Djokovic's ninth win in as many meetings against the world number 42, who has never taken a set off the Serb.

Federer, the 2009 French Open champion, beat qualifier Diego Sebastian Schwartzman 6-3, 6-4, 6-4.

The fourth-seeded Swiss is to play Russian 31st seed Dmitry Tursunov in the third round.
