PARIS (Reuters) - World number three Novak Djokovic survived a second-set lapse before beating Romania's Victor Hanescu 6-3 3-6 6-3 6-2 to book his place in the fourth round of the French Open on Saturday.
In a seesaw performance, the Serbian pumped his fists and smashed his racket onto the ground as he struggled to break Hanescu's resilience on Center Court.
He came back from a break down, however, in the fourth set to win six games in a row, wrapping up the win when the 31st-seeded Hanescu misfired a service return after two hours and 38 minutes.
Next in line for Djokovic is American Robby Ginepri.
Djokovic, twice a semi-finalist at Roland Garros, believes he will be physically fit for the challenge after skipping the Madrid Masters earlier this month.
"This year I have not done that great on the clay courts because of some other reasons," the Serbian, who has been struggling with allergies, told reporters.
"I did not do as well as I did in 2009, but the good thing about taking a break is that I'm fresh and ready here in Paris.
"I do fell it on the court and hopefully I can feel it in the next week."
