Heavy Spanish crowd favorites Rafael Nadal and David Ferrer reached the quarterfinals, while Argentine star David Nalbandian was among Thursday's third-round losers at the $1.29 million Open Sabadell Atlantico tennis event.
The top-seeded and three-time defending Barcelona champion Nadal handled 16th-seeded fellow Spaniard Feliciano Lopez 6-4, 6-3 on the red clay at Barcelona Tennis Club.
The reigning three-time French Open titlist Nadal is fresh off his fourth straight Monte Carlo championship last week, having beaten world No. 1 Roger Federer in a lucrative final.
Meanwhile, the second-seeded 2007 Masters Cup runner-up Ferrer came from behind to beat Ecuador's Nicolas Lapentti 4-6, 6-4, 6-3 and setup a quarterfinal against sixth-seeded fellow Spaniard Tommy Robredo, who dismissed a ninth-seeded Canas 6-1, 7-5 on Day 4 here. Robredo captured this event back in 2004.
A third-seeded Nalbandian succumbed to 14th-seeded Swiss Stanislas Wawrinka 6-3, 6-1.
In other third-round play, 10th-seeded Spanish clay-court specialist Nicolas Almagro defeated Croatian wild card Mario Ancic 7-6 (7-5), 6-2, German Denis Gremelmayr upended 15th-seeded Russian Dmitry Tursunov 6-4, 6-0 and Spaniard Albert Montanes outlasted Russian qualifier Mikhail Kukushkin 6-3, 3-6, 6-3.
Friday's other quarters will pit Almagro against Gremelmayr and Wawrinka versus Montanes.
The 2008 Barcelona winner will collect $210,000.
