Rafael Nadal insists he is not feeling the pressure of attempting to win a third straight French Open title.

The Spaniard extended his unbeaten run at Roland Garros to 16 matches thanks to Thursday's run-of-the-mill 6-2 6-1 6-4 victory over Flavio Cipolla on Suzanne Lenglen court.

The Spaniard, who is yet to be defeated here since making his debut in 2005, is bidding to become the first man since Bjorn Borg in 1980 - and only the second in 93 years - to win three Roland Garros titles on the trot.

His recent run of 81 matches undefeated on clay came to an end a week and a half ago when he lost the final of the Masters event in Hamburg to Roger Federer.

He is still favourite to claim the title at Roland Garros this year, but is adamant the burden of expectation is not weighing him down.

'Everyone wants to win matches here, so I don't feel pressure any more than anyone else,' said the 20-year-old.

'Federer, (Tommy) Robredo, Carlos Moya, all of these people coming here who want to win have to cope with a certain level of pressure.

'But it's business as usual. There's only one way you can eliminate pressure and that's by playing well.'

Nadal was steady, if not spectacular, in his one hour and 53 minutes on court against Cipolla.

The Italian, at 227th in the world, was the second lowest-ranked player to reach the second round, and he failed to seriously trouble Nadal throughout.

Dark horse Lleyton Hewitt demonstrated his renowned fighting qualities to recover from going two sets down to defeat former champion Gaston Gaudio in today's outstanding match at Roland Garros.

The Australian, seeded 14th, is known for his grit and determination and he needed it as he claimed a 4-6 3-6 6-2 6-4 6-2 win in almost three-and-a-half hours on Philippe Chatrier court.

The win sets up a third-round clash with Jarkko Nieminen, but he admitted Gaudio caused him all sorts of problems early on.

'He was probably one of the toughest second-round matches you can get here,' said the former world number one, who lost to Gaudio during the Argentinian's run to the title three years ago.

'He was hitting his backhand great, and he wasn't missing many balls.

'It was a matter of just hanging in there, and just focusing on winning one set at a time.'

Nieminen, seeded 20, thrashed Mathieu Montcourt, of France, 6-1 6-1 6-4 on Court Three, and Hewitt is expecting a tough next match.

'He is a good player,' he said. 'He is a left-hander, but good off both sides.

'It will be a different kind of match to this one.'

Marcos Baghdatis had it almost as straightforward as Nieminen in his second-round match.

The Cypriot defeated Denmark's Kristian Pless 7-5 6-3 6-4 on Court 1 to reach the third round at Roland Garros for the first time in three attempts.

He will next play Jan Hajek, who beat fellow Czech Bohdan Ulihrach in five sets.

Meanwhile, Serbia's Novak Djokovic, the sixth seed, secured a four-set victory over Frenchman Laurent Recouderc.

The 20-year-old Djokovic, a quarter-finalist at Roland Garros last year, won 6-3 3-6 6-3 6-1 on Suzanne Lenglen court.

Ivo Ljubicic, seeded seven, joined him in the third round thanks to a 6-4 6-3 6-7 (3-) 6-3 triumph over Switzerland's Stanislas Wawrinka.

He will play 29th-seed Filippo Volandri next, and said: 'It's not easy, but I have had a good draw many times and still not made it.

'He is having an extra day's rest, so it's definitely an advantage for him.'

Spanish duo Carlos Moya and David Ferrer also progressed with comfortable wins against Florent Serra and Diego Hartfield, respectively.

Other winners today were Olivier Patience, who defeated Mariano Zabaleta in five sets, and Juan Pablo Brzezicki - a straight-sets victor over Guillermo Garcia-Lopez.
