Barcelona:Tommy Robredo and David Nalbandian advanced to the third round of the Open Seat Godo and left behind former champions Marat Safin and Gaston Gaudio on Tuesday.
Third-seeded Robredo beat fellow Spaniard Feliciano Lopez 6-2, 6-2 with five service breaks and 33 first-serve winners. To reach his first quarterfinals since January in Auckland, New Zealand, Robredo next faces 15th-seeded Agustin Calleri of Argentina.
"I was nervous about playing at home but I'm happy with the match," said Robredo, the 2004 champion and runner-up last year to Rafael Nadal.
"It's great to be back at No. 5 (in the ATP rankings) let's see how long it lasts. I'm not in top physical shape but my technique and mental approach are all right."
Fourth-seeded Nalbandian routed Alberto Martin of Spain 6-2, 6-0 and earned a shot at his first quarterfinals this season.
In first-round matches, 2000 champ Safin and 2002 winner Gaudio lost in straight sets.
