Melbourne - Third seed David Ferrer wore down Frenchman Adrian Mannarino to reach the third round of the Australian Open on Wednesday.
The Spaniard beat the 71st-ranked Mannarino 7-6 (7/2), 5-7, 6-0, 6-3 in just over three hours on Hisense Arena.
It was a tough work-out for the super-fit Spaniard, who lost the second set and had his serve broken five times.
Ferrer made 48 unforced errors to his 32 winners, while the Frenchman committed 73 errors.
The Spaniard is defending rankings points from his losing semi-final appearance against Novak Djokovic at last year's Australian Open.
Last year Ferrer reached the final of the French Open where he lost in straight sets to countryman Rafael Nadal.
