PARIS - Novak Djokovic and Andy Murray reached the French Open third round Thursday, setting up intriguing clashes with next generation Australians, Thanasi Kokkinakis and Nick Kyrgios. Top seed Djokovic survived a worrying injury scare before coasting to a 6-1, 6-4, 6-4 win over Gilles Muller of Luxemburg.

Djokovic will face 19-year-old Kokkinakis who saved three match points to beat fellow Australian Bernard Tomic 3-6, 3-6, 6-3, 6-4, 8-6. Djokovic's win over 33-year-old Muller was his 24th consecutive victory this year as he took another step towards a first ever Roland Garros title and a career Grand Slam. However, he needed a medical timeout leading 5-4 in the second set for treatment on what appeared to be a right groin strain. It didn't affect him too much as he quickly wrapped up the second set with a service game to love. He eventually wrapped up the tie on after just an hour and 45 minutes, hitting an impressive 35 winners. Kokkinakis, making his Roland Garros debut on a wildcard, came back from 2-5 down in the decider to defeat his 27th-seeded compatriot Tomic.

He fired 19 aces and 71 winners despite taking a medical timeout after a nasty fall. The young Australian is the first teenager to reach the third round in Paris since 2008. "Novak barely misses a ball, he's mentally tough, lightning quick on court. The list goes on," said Kokkinakis. Murray, the third seed, went into the last 32 with a 6-2, 4-6, 6-4, 6-1 win over Joao Sousa of Portugal. The Scot took his record to 12-0 on clay this season and he will meet 20-year-old Kyrgios who enjoyed a walkover into the third round when scheduled opponent Kyle Edmund of Britain withdrew with a stomach injury. "I realised towards the end of the second set he raised his level and I had to tell myself to weather the storm and his level would drop," said Murray.

Defending champion and sixth seed Rafael Nadal, chasing a 10th Paris title, enjoyed a 6-4, 6-3, 6-1 breeze past Spanish compatriot Nicolas Almagro. Nadal will face Andrey Kuznetsov for a place in the last 16 after the Russian defeated Austria's Jurgen Melzer 6-1, 5-7, 7-6 (7/0), 7-5.

"I am very happy. I played a great match and was very solid," said nine-time champion Nadal who has now defeated Almagro 13 times out of 14. "There were long games, the match was not as easy as the score may suggest." The 28-year-old Nadal now has 68 wins at the tournament and just one loss. US Open champion Marin Cilic reached the third round for the fourth successive year. The ninth-seeded Croatian fired 38 winners in a 7-6 (7/3), 6-1, 6-1 win over Italian qualifier Andrea Arnaboldi. Cilic will face Argentine 23rd seed Leonardo Mayer who beat Jerzy Janowicz of Poland 6-4, 6-4, 6-7 (1/7), 6-1 for a place in the last 16. This year's second round featured a record 19 men over the age of 30. But 33-year-old German Benjamin Becker won't be going any further after he was forced to withdraw from Friday's scheduled third round clash with Japan's fifth seed Kei Nishikori because of a right shoulder injury.

 Nishikori will face either Lukas Rosol of the Czech Republic or Teymuraz Gabashvili of Russia for a place in the quarter-finals.
