Ramos, coming off his first career semifinal in Umag, Croatia last week, will next play eighth-seeded fellow Spaniard Pablo Andujar, who rallied to beat Lukas Rosol of the Czech Republic 3-6, 6-3, 6-3.

Two more Spanish players advanced after Pere Riba downed Romania’s Victor Hanescu 7-6 (3), 6-4, and Daniel Gimeno-Traver defeated wildcard Dominic Thiem 6-4, 6-2 in the Austrian’s first match on the ATP World Tour.
