Federer needed four sets to see off Tursunov's challenge.

World No.1 Novak Djokovic and 2009 champion Roger Federer both needed four sets to reach the fourth round of the French Open as another high-profile contenders crashed out of the women's draw.

No.3 seed Agnieszka Radwanska, the highest ranked played remaining, was dumped out in the third round after a straight sets defeat to Ajla Tomljanovic.

The Polish player's exit follows Li Na and Serena Williams' departure from the tournament as the women's draw continues to throw up major shocks.

New favourite Maria Sharapova set-up a fourth round meeting with Sam Stosur after a double bagel win over Paula Ormaecha, while the Australia overcame Dominika Cibulkova.

The bottom half of the men's draw continues to go with the form book but both Djokovic and Federer were taken to four sets by respective opponent Marin Cilic and Dimitry Tursunov on Friday.

Djokovic, a finalist at Roland Garros in 2012, claimed the opening two sets against Cilic without alarm before clinching a break in the third.

But the Croat rallied to take the set on a tie-break, however Djokovic defied the comeback and took the fourth set after a double-fault on match-point to clinch a ninth straight win over Cilic.

Meanwhile, Federer required shades of his very best to stifle Tursunov's return in 2014. The Russian saved set points before levelling the match in a second set tie-break before the 17-time grand slam champion powered into the fourth round for a 12th year in a row.

"It was tough to lose the second [set] but nice to win the match. It was as expected not a straight forward easy match and I knew Dimitry was going to try different things," Federer said. "I am pleased I found a way [to win] and played it solid until the very end."

The Swiss will play Ernests Gulbis in round four after a sublime showing saw off Radek Stepanek in three sets.

"Today I'm very pleased," the Latvian said. "Today I served well. He had only one break point. Served, yeah, average, one to two aces a game. Any opponent is going to have trouble with that.

"I was surprised he [Stepanek] didn't change up the return a little bit, but, yeah, the serve was working today, so that was the key."
