French Open 2015: Rafael Nadal and Novak Djokovic win in Paris

Novak Djokovic, Serena Williams and Rafael Nadal are into the French open third round

• Nadal has now won 68 of 69 French Open matches

• Djokovic had medical time-out before victory

• Williams meets Victoria Azarenka in third round

• Wozniacki has never got past French quarters

Rafael Nadal and Novak Djokovic are on course for a French Open quarter-final meeting after both reached the third round in straight sets.

Nadal, 28, bidding for a 10th title at Roland Garros, saw off fellow Spaniard Nicolas Almagro 6-4 6-3 6-4.

World number one Djokovic beat Luxembourg's Gilles Muller 6-1 6-4 6-4, despite treatment on his lower back.

And top seed Serena Williams survived losing the first set to beat Germany's Anna-Lena Friedsam 5-7 6-3 6-3.

But fifth seed Caroline Wozniacki lost to Germany's Julia Goerges, ranked 72nd in the world, 6-4 7-6 (7-4).

Going long on Court One

Svetlana Kuznetsova is a two-time Grand Slam champion who won at Roland Garros in 2009

The 2010 winner Francesca Schiavone won a mammoth battle of former champions, overcoming 2009 predecessor Svetlana Kuznetsova 6-7 (11-13) 7-5 10-8 in three hours 49 minutes.

The match featured 206 points - more than double the 95 that made up Irina-Camelia Begu's 6-2 6-0 win over Croatia's Ana Konjuh earlier in the day - and is the third longest women's singles match in French Open history.

The pair have form for lengthy contests.

At the 2011 Australian Open Italian Schiavone beat her Russian opponent 6-4 1-6 16-14 in four hours and 44 minutes, setting the record for the longest women's match in Grand Slam history.

Djokovic laid back over injury

Djokovic lost last year's final in four sets to Rafael Nadal

Top seed Novak Djokovic, who is hunting a French Open title that would complete his collection of career Grand Slams, extended his 2015 record to 37 wins from 39 matches with a routine victory over Muller.

Despite receiving lengthy treatment after a fall during the match, the Serb is confident that injury won't hold him back against Thanasi Kokkinakis in the next round.

"Thankfully it's nothing serious, really," he said.

"I slipped a lot and felt pain in the right leg, but I'm not worried about it."

Teenage kicks

Thanasi Kokkinakis is Australia's number five behind Tomic, Nick Kyrgios, Sam Groth and James Duckworth

Australian Kokkinakis became the first teenager to reach the men's third round at Roland Garros since Ernests Gulbis made the quarters in 2008.

The 19-year-old beat compatriot and 27th seed Bernard Tomic in a five-set thriller, winning 8-6 in the fifth.

Tomic, who lost 3-6 3-6 6-3 6-4 8-6, will get cortisone injections on his aching lower back before the grass court season and Wimbledon.

"I've never done that before," Tomic said of the jabs. "Hopefully, that will get rid of the area that has been bothering me. But I have no idea about this stuff.

"I had a bunch of match points this year. If I had converted them all I probably would have been close to the top 20 or even top 20 now, for sure,'' said the current world number 26.

Wintour chill around Roland Garros

Vogue editor-in-chief Anna Wintour took up her seat early on Philippe-Chatrier to catch Goerges' win over Wozniacki in the first match of the day.

Perhaps she was drawn by the players' sartorial imagination with both in shades of yellow, defying the trend for black and pink that has dominated the locker room so far in the tournament.
