Nikolay Davydenko and Anna Chakvetadze each won Kremlin Cup titles in all-Russian finals Sunday.

Top-seeded Davydenko, the 2004 champion, beat Marat Safin 6-4, 5-7, 6-4 for his fourth title this season and Chakvetadze upset fifth-seeded Nadia Petrova 6-4, 6-4 for her second straight win.

Chakvetadze won her first title two weeks ago at the Guangzhou Open in China.

The fifth-ranked Davydenko made a decisive break in the sixth game of the first set.

He broke twice early in the second set, but Safin broke back and then saved three match points in the ninth game. Safin converted his only break point and evened the match at 1-1.

``If I had held in the first games of the third set, I would have a chance in the match,'' Safin said.

Petrova, playing with groin and chest injuries, saved four break points in the seventh game of the first set before dropping her serve. She broke back immediately, but lost her next service game and ultimately the set _ only the second set she had lost in five matches.

Chakvetadze continued to control play in the second set and broke twice to lead 4-1. Though Petrova broke back in the sixth game, Chakvetadze improved her record against her opponent to 3-0 this season.

``I was lucky today,'' Chakvetadze said. ``Petrova wasn't 100 per cent fit today.''

The 24th-ranked Chakvetadze will move into the top 20 for the first time in her career next week. Petrova, who will remain at No. 5, said injuries affected her chances.

``I had my chest and hips bandaged and it was difficult to serve and move _ I did all I could,'' Petrova said.

The loss was Petrova's first in six finals this season. She won her sixth career title at the Porsche Grand Prix last week in Stuttgart, Germany.
