Tursunov storms into last eight

Second-seeded Israeli Dudi Sela converted only one seven break points on his way to a 6-4, 7-6 loss to Russian-born qualifier Alex Bogomolov, while American Wayne Odesnik recovered to beat -ourth seeded Russian Igor Kunitsyn 2-6, 6-1, 6-1.

Former champion Tursunov's routine win over Brazil's Daniel set up a last-eight encounter against familiar foe Frank Dancevic, who advanced with a 6-2, 7-5 over fifth-seeded Benjamin Becker of Germany.

Third-seeded American Sam Querrey also booked a spot in the last eight with a 7-5, 6-3 victory over compatriot Rajeev Ram, gaining some revenge over the man who beat him in the Hall of Fame Championships final earlier this month.

Chardy ousted
In Berlin, Russian second seed Nikolay Davydenko ended Frenchman Jeremy Chardy's six-match winning streak on Thursday with a 6-3, 6-3 victory to advance to the German Open quarterfinals.

Davydenko thus set up a quarterfinal clash with Romanian Victor Hanescu. Hanescu came from a set down to defeat Frenchman Julien Benneteau 3-6, 6-3, 6-3.

Rain interrupted play on all clay courts for several hours, except centre court which has a retractable roof, where Uruguayan qualifier Pablo Cuevas swept past German eighth seed Philipp Kohlschreiber 6-4, 7-6 to move into the last eight.

Cuevas next meets Nicolas Almagro, after the Spaniard defeated third-seeded Swede Robin Soderling 7-5, 6-3. Paul-Henri Mathieu, seeded 13th, struggled to beat German wild card entrant Daniel Brands 7-5, 7-5.
