STUTTGART, Germany(AP) Svetlana Kuznetsova upset second-seeded Elena Dementieva 6-4, 6-2 Saturday to reach the final of the Porsche Grand Prix.

The fifth-seeded Kuznetsova made the Stuttgart final for the first time after getting knocked out in her three previous semifinals.

``I surprised myself a little bit. I was extremely focused,'' Kuznetsova said.

She will play either top-ranked Dinara Safina or Flavia Pennetta in Sunday's final.

Kuznetsova improved her career record to 6-4 over Dementieva, who leads the tour with 29 wins this year and has two titles.

In an all-Russian semifinal, Kuznetsova took a 3-1 lead. She set the pace from the baseline, moving Dementieva around the court.

``I wanted to come and be aggressive, I controlled the court,'' Kuznetsova said.

Dementieva tied it 3-3 but Kuznetsova broke serve again to win the first set.

She also took a decisive 3-0 lead in the second set before reaching her first final of the year. On the final two points, Dementieva she netted what should have been a simple drop volley, then hit a backhand way long to lose the match.

I was too passive, I didn't attack her,'' Dementieva said.I did not play at my high level.''

Previously a hardcourt tournament, it's the first indoor event on clay on the WTA circuit.
