Davydenko Into Sopot Quarters, Calleri Extends Streak

The Russian failed to convert three match points in the second set tie-break and then needed an additional five match points in the final game of the match before claiming victory with his eighth match point. Davydenko, who is No. 6 in the INDESIT ATP Rankings -- just once place below his career-high mark -- improved to 41-20 on the season. He remains on track to pass 50 match wins for the second consecutive season after last year's career-best 56-30 record.

With the exception of a surprise first-up loss in Kitzbuehel last week, Davydenko has been in hot form on clay his season. Before Kitzbuehel, in his past four clay court tournaments the 25-year-old reached the Bastad final, the Roland Garros quarterfinals, won Poertschach and reached the Masters Series Hamburg quarterfinals.

Eighth seed Agustin Calleri, chasing consecutive titles after winning in Kitzbuehel last week, extended his winning streak to seven matches after defeating Dutchman Raemon Sluiter 6-4, 6-4 to reach the quarterfinals.

German Florian Mayer, who in his past two outings won the Tampere Challenger and reached the Stuttgart quarterfinals (l. eventual champion Ferrer), upset second seed Tommy Robredo 6-2, 6-4.

Michal Przysiezny became the first Polish player to reach an ATP quarterfinal in 20 years (Wojtek Fibak in Rotterdam in 1986) when he defeated Czech Jiri Vanek 6-3, 6-1.
