PARIS (Reuters) - World number three Caroline Wozniacki came out on top in a three-hour tussle to down Italian Flavia Pennetta 7-6 6-7 6-2 in the fourth round of the French Open on Sunday.
The Dane, who reached the last eight of a grand slam on one previous occasion when she lost the U.S. Open final last year, had more fuel in the tank as the 14th-seeded Pennetta stalled in the decider.
Wozniacki, who broke Pennetta's serve 10 times, won the last four games and ended the contest on her third match point when Pennetta netted a forehand.
She will next face another Italian, 17th-seeded Francesca Schiavone, for a place in the last four. (Reporting by Julien Pretot; editing by Miles Evans; To query or comment on this story email email@example.com)
