Acapulco - Rafael Nadal's return from injury gathered pace Wednesday as the former world No 1 downed Argentina's Martin Alund 6-0, 6-4 to reach the Mexican Open quarter-finals.
The second-seeded Nadal needed just 85 minutes to beat Alund at the clay court tournament and will next face another Argentine in Leonardo Mayer, who defeated Russia's Andrey Kuznetsov 6-2, 6-2 to advance.
Top Seeded David Ferrer earlier downed American Wayne Odesnik 6-2, 6-1 to book his place in the final eight.
Nadal is making a comeback after being away from the tour for more than seven months with a left-knee injury. He made the final of the VTR Open earlier this month in Chile before losing to Argentine Horacio Zeballos. A week later he beat David Nalbandian to claim the Brazil Open title.
