French Open:Roger Federer survived a bumpy ride this afternoon to beat claycourt specialist Argentine Jose Acasuso 7-6 5-7 7-6 6-2 to reach the third round of the French Open. The Swiss world number two was 5-1 down in the third set, saving a set point at 5-2 on his way to winning five games in a row to force a tie-break which he snatched with a sizzling serve that his 45th-ranked opponent could not control.

Federer had not made it easy for himself in a protracted first set, eventually taking it to a tie-break where he saved four set points before pulling back to snatch the set for himself with a tidy dropshot on his second set point.

Acasuso gave the Swiss a few lessons in how to play on his least favourite surface in the second but after seeing his chance of an upset evaporate in the third, he went out with a whimper in the fourth when he messed up a service return.

Venus Williamsflirted even closer with danger and had to save match point in her clash with Lucie Safarova.

The third seed was a point from defeat at 4-5 30-40 in the final set but produced a fine backhand winner to stay alive and went on to record a 6-7 (5/7) 6-2 7-5 victory.

Asked how she felt staring down the barrel of defeat, Williams explained she just went on instinct.

"I wasn't thinking," she said. "Not at all.

"(In that situation) I probably just stick to my technique - rely on that. Thankfully, I wasn't thinking. It just happened, so it was great."

Williams added: "It was just one of those matches that feels really good to win, because obviously the level of play was so high."

In contrast to her sister, Serena Williams, strolled into the third round.

The second seed had struggling in her opening match but on Thursday she crushed Virginia Ruano Pascual, at 35 the oldest player in the draw, 6-2 6-0.

The American star will now play another Spaniard, Maria Jose Martinez Sanchez, for a place in the last 16.

Svetlana Kuznetsovaand Jelena Jankovicalso wasted little time in reaching the last 32.

Kuznetsova, the 2006 runner-up, crushed Galina Voskoboeva 6-0 6-2 in just 49 minutes, while Jankovic recorded a 6-1 6-2 victory over Slovakia's Magdalena Rybarikova.

Jankovic is happy that she is returning to something approaching her best form after a disappointing run of late.

She said: "When you see how I was playing a few months ago, it was really disastrous. I wasn't moving well, I was making so many errors, my game was completely off, as well as my confidence.

"Now I think I'm on the right track. I want to get back into the spotlight."

Caroline Wozniacki (10)was another seed to enjoy smooth progress. She beat American Jill Craybas6-1 6-4.

But one seed to fall early on day five was French number one Marion Bartoli.

The former Wimbledon finalist was beaten 6-3 7-5 by veteran Italian Tathiana Garbin.

There was more woe for the home fans later in the day when 21st seed Alize Cornetlost 6-3 6-2 to Sorana Cirstea, although Virginie Razzanolifted spirits later in the day as she toppled 18th seed Anabel Medina Garrigues, posting a 6-2 6-2 victory.

There was also a rare straight-sets win on clay for Andy Roddick.

The former US Open champion has always struggled at Roland Garros but he eased his way into the third round for only the second time in eight visits with his 6-2 6-2 7-6 (7/2) victory over Ivo Minar. He faces Gicquel next.

Nikolay Davydenkoquickly wrapped up victory in his delayed clash with Diego Junqueira.
