ACAPULCO (Reuters) - Former world number one Rafa Nadal breezed through to the semi-finals of the Mexican Open on Thursday, dispatching Argentine Leonardo Mayer in straight sets 6-1, 7-5.
The second-seeded Nadal will face fellow Spaniard Nicolas Almagro on Friday.
Nadal, an 11-time Grand Slam champion, is in the midst of a three tournament comeback after a knee injury forced him to take a seven-month hiatus from the tour.
Earlier this month Nadal made the final of the VTR Open in Chile, and followed that up by claiming the Brazil Open title.
