Gael Monfils battled through to the quarterfinals of the French Open on Monday by beating David Ferrer 6-4, 2-6, 7-5, 1-6, 8-6 in a match that stretched over two days and lasted more than four hours.
The ninth-seeded Monfils, a semifinalist at Roland Garros three years ago, will next play Roger Federer.
The Frenchman sealed the win on his fourth match point with a forehand passing shot.
Monfils was leading the seventh-seeded Ferrer 6-4, 2-6, 7-5, 0-2 on Sunday when their match was suspended because of darkness.
Monfils is playing in his sixth tournament of the year after being hampered by a left wrist injury.
This is the first time since 2002 that two French players will be in the quarterfinals at Roland Garros. Marion Bartoli has also advanced.
