Top-seeded David Ferrer made the Valencia Open quarterfinals by easing past Julien Benneteau of France 6-2, 6-1 on Thursday.
Benneteau squandered four break points against the Spaniard and, as Ferrer acknowledged afterwards, "the score doesn't reflect how tough this match was."
The match had tense rallies in the first set and Ferrer said it was tough, physically.
Jeremy Chardy of France provided spectators with a second-round upset when he broke fourth-seeded John Isner of the United States three times to win 7-6 (7), 6-3.
Other winners included fifth-seeded Jerzy Janowicz of Poland, who will next face Ferrer, Jarkko Nieminen of Finland and Mikhail Youzhny of Russia, who will also meet on Friday, and third-seeded Nicolas Almagro of Spain.
