"I'm very happy to have reached my first semifinal in Bastad," Davydenko said. "It was difficult to control the ball because of the strong winds, but I still managed to play well."
Davydenko won 6-4, 6-3 before a sold out center court crowd of nearly 7,000. In the semi-finals, the Russian will play the winner of a quarterfinal later on Friday between Agustin Calleri of Argentina and Robin Soderling, the only Swede left in the clay-court event.
Davydenko broke to lead 2-1 with a backhand return and that was all he needed to take the opening set. In the second set, he broke the Chilean 1-0 and then again to love for a 5-2 lead.
This was the ninth quarterfinal of the year for the 25-year-old Davydenko, who has a career-best ATP ranking of No. 5. Davydenko also reached the quarterfinals here in 2002, but lost to Carlos Moya.
