Third-seeded David Ferrer overcame a slow start to beat Adrian Mannarino of France 7-6 (2), 5-7, 6-0, 6-3 in a second-round match Wednesday at the Australian Open.
Ferrer trailed 3-0 in the opening set before rallying in the tiebreaker, then fell behind 4-1 in the second before taking control in the final two sets.
