Nadal moves on in Mexico

Rafa Nadal's comeback continued with a 6-0 6-4 victory over Martin Alund of Argentina in the second round of the Mexican Open.

The second seed required just 85 minutes to see off Alund in Acapulco and book a last eight clash with another Argentine in Leonardo Mayer.

Nadal, returning from a seven month injury absence, reached the final in Chile earlier this month before winning the Brazil Open.

The win came a fortnight after Alund took Nadal to three sets in Sao Paulo, saving all three break points he faced.

"The first set I played at a very high level," Nadal said. "I started strong without any errors. In the second set Martin played at a high level and made it hard to close it out.

"I'm happy to be in the quarter-finals."

Mayer overcame Andrey Kuznetsov 6-2 6-2 to earn his date with Nadal, while top seed David Ferrer eased past American Wayne Odesnik 6-2 6-1 to reach the quarter-finals.

Ferrer next faces Italian Paolo Lorenzi, a 6-4, 6-3 winner over Spain's Pablo Andujar.

There was also success for third seed Nicolas Almagro, who defeated fellow Spaniard Tommy Robredo 6-4 7-6, while the other seed in action, eighth-ranked Horatio Zeballos, beat Daniel Gimeno 6-2 6-3.
