Djokovic moves into French Open round of 16 with 4-set win

Paris, May 30 (EFE).- Serbian Novak Djokovic booked a spot in the French Open round of 16 with a 6-3, 6-2, 6-7 (2-7), 6-4 victory Friday over Marin Cilic.

The world No. 2, who is seeking to capture the only Grand Slam title that has eluded him in his career, cruised through the first two sets but then found himself in a tough battle with the big-hitting Croat.

Cilic broke the Serbian's serve on three occasions but lost his own service seven times during the three-hour, 11-minute match.

He won a third-set tiebreaker to extend the match and rallied from a 3-0 deficit to even the fourth set at 4-4, but the Serb took the contest two games later when Cilic double-faulted on match point.

"It wasn't easy, because, you know, once you start being passive, you know, you lose kind of the confidence to step in. That's what happened maybe in the end of the third and, you know, a little bit of the fourth," Djokovic said in the post-match press conference.

"In important moments I held my nerves and, you know, I'm very happy that I went through."

In other men's singles results Friday, Swiss No. 4 seed Roger Federer defeated Russia's Dimitry Tursunov 7-5, 6-7 (7-9), 6-2, 6-4 and Czech No. 6 seed Tomas Berdych topped Spain's Roberto Bautista Agut 6-1, 6-2, 6-7 (4-7), 6-4.

Polish No. 3 seed Agnieszka Radwanska was the latest upset victim in the women's singles, falling 6-4, 6-4 Friday to Croatia's Ajla Tomljanovic.

Earlier in the tournament, American top seed and defending champion Serena Williams and second-seeded Li Na of China were ousted from this premier clay-court event.

Those losses have left fourth-seeded Romanian Simona Halep as the top-ranked player left in the women's singles draw.

In other action Friday, seventh-seeded Russian Maria Sharapova cruised into the fourth round with a 6-0, 6-0 shellacking of Argentina's Paula Ormaechea.
