French Open: Roger Federer and Novak Djokovic in the groove
Novak Djokovic and Roger Federer showed the tennis world has not completely spun off its axis by moving smoothly into the third round of the French Open.
After Australian Open champions Stan Wawrinka and Li Na made unwanted history by falling in the first round, the biggest shock of the lot arrived when Serena Williams crashed out.
Federer followed Williams onto Court Suzanne Lenglen, and he did not have things all his own way against qualifier Diego Sebastian Schwartzman but was comfortable enough in a 6-3 6-4 6-4 victory.
Federer said: "It was kind of tough. I didn't feel relaxed for the entire match. I always felt he had an upper hand from the baseline."
Djokovic had the upper hand in every area of his match against Frenchman Jeremy Chardy as he eased to a 6-1 6-4 6-2 victory.
Both men could sympathise with Wawrinka who, after losing to Guillermo Garcia-Lopez on Monday, admitted he was finding it difficult adjusting to everything that comes with being a grand slam champion.
Djokovic won his first grand slam title at the Australian Open in 2008 but did not win another for three years.
He said: "I can say from my side I always have high ambitions for myself. But with that there is a lot of responsibility, a lot of hard work, a lot of understanding on and off the court, what you need to do and what you need to become in order to be successful."
Djokovic faces a potentially tricky match next against 25th seed Marin Cilic, who beat Tobias Kamke in four sets, while Federer meets 31st seed Dmitry Tursunov.
Sixth seed Tomas Berdych had to fight back from a set down on his way to a 6-7 (4-7) 6-4 7-5 6-3 victory over Kazakh Aleksandr Nedovyesov and will play in-form Spaniard Roberto Bautista Agut.
French number one Jo-Wilfried Tsonga had a straight-sets win over Jurgen Melzer.
