The defending champion at the clay-court event injured the foot in the first round. The 26-year-old Russian received medical attention before deciding to retire.

"Normally I try to fight to the end, but it was very painful and I may have done even more damage by trying to finish the match," Davydenko said. "Since the beginning of Monday I've had a problem with my left toes. Today that became a problem with my foot."

Also Thursday, second-seeded Tommy Robredo of Spain overcame a poor first set and erratic play to down Steve Darcis of Belgium 1-6, 6-0, 7-5.

Robredo next plays Stefan Koubek of Austria, who defeated Kristof Vliegen of Belgium 6-2, 3-6, 6-4 earlier in the day.

Arguello will play Albert Montanes of Spain for a spot in the semifinals. Montanes rallied to beat Mariano Zabaleta of Argentina 4-6, 6-3, 7-5 earlier Thursday.
