Federer eases into the second round with few problems
Roger Federer eased into the second round of the French Open with a 6-4 6-4 6-3 victory over American Sam Querrey.
Querrey provided the world number one with a decent workout, but Federer was always in control and next faces Albert Montanes or Kristof Vliegen.
"It's always difficult in the first round at Grand Slams," said Federer. "I'm relieved and looking forward to the second round."
Heavy rain saw play suspended before Rafael Nadal took on Thomaz Bellucci.
Marcos Baghdatis, the 17th seed, lost 6-2 6-4 6-2 to Simone Bolelli of Italy.
"That's the way it is, that's tennis," said Baghdatis, who has just returned to action following a month off for personal reasons.
"He played better than I did today."
Federer took a while to get going, letting an early lead slip in the first set, but he was rarely threatened by 6ft 6in Querrey and took the match in one hour 35 minutes.
"He's an up-and-coming player who has got a good serve and big shots. On the day you don't know what's going to happen and that's why it's sort of nerve-wracking.
"Practice is one thing but today the atmosphere is different, the court full, the pressure is there. That's why I'm sort of relieved getting through the first one.
"From now it should get a little bit easier."
Tommy Robredo, the 12th seed, rallied to beat former finalist Guillermo Coria 5-7 6-4 6-1 6-4.
Coria was playing his first Grand Slam match for nearly two years after back and shoulder injuries.
"I thought about retirement," said the former world number three. "A month ago I didn't think I would play here but Roland Garros means a lot to me. It's like another home.
"In the last three weeks the situation has changed and I'm eager to be back on tour."
Tomas Berdych of the Czech Republic made an almost perfect start as he thrashed Australian Robert Smeets 6-1 6-0 6-0.
Fernando Gonzalez, the number 24 seed, was another comfortable winner, crushing Uraguay's Pablo Cuevas 6-3 6-3 6-1.
But Guillermo Canas - three-times a quarter-finalist at Roland Garros - suffered a surprise 7-6 (8-6) 7-6 (7-3) 7-6 (8-6) defeat by American wildcard
