MADRID, Spain -- Nadia Petrova and Elena Dementieva put Russia into the finals of the Fed Cup with singles victories over France on Friday.

The Russians, seeking their first Fed Cup title, will face the winner of Saturday's matches between Spain and Belgium in the final Sunday. Belgium is also seeking its first title and Spain has won five times.

Petrova defeated Sandrine Testud 6-7 (5), 6-4, 6-4 and Dementieva won over Amelie Mauresmo 6-3, 0-6, 6-4. The two singles victories on indoor clay gave Russia a perfect record of 3-0 in Pool A play following earlier victories over the Czech Republic and Argentina.

In the meaningless doubles match Friday, Nathalie Tauziat and Virginie Razzano of France beat Elena Likhovtseva and Elena Bovina of Russia 7-6 (5), 6-1.

Petrova, 19, dropped the first set but took the next two with a stronger serve and a better return game. She needed four match points to win.

"I wasn't nervous until I hit match points, then I realized I needed just one, it's the end of the game and I need one point. She (Testud) played unbelievable points and I thought: `Why don't you miss it, make my life easier'."

Dementieva, 20, had a similar struggle and needed three match points to finally get the victory. The 1 -hour-58 minute match was interrupted three times by short power failures that dimmed the court lights.

Belgium and Spain also won on Friday to push their Fed Cup round-robin records to 2-0 in Pool B, setting up a showdown with the winner going to Sunday's finals.

Justine Henin defeated Australia's Rachel McQuillan 7-5, 6-0 and Kim Clijsters won 6-3, 6-3 over Alicia Molik to give Belgium an insurmountable 2-0 lead in the best-of-three tie. The doubles teams of Els Callens and Clijsters completed the sweep 6-4, 6-2 over McQuillan and Molik.

Spain had to work harder.

German teen-ager Martina Muller upset veteran Conchita Martinez 6-1, 7-5. But Arantxa Sanchez-Vicario rallied to beat Barbara Rittner 7-5, 6-3 in the second singles. In doubles, Sanchez-Vicario teamed with Virginia Ruano Pascual for a 6-3, 2-6, 6-0 victory.

Henin, 19, has hardly had to exert herself in two singles victories.

"It's nice to have an easy match, but it's not finished yet. We have to win one more match," Henin said. "We are at the door of the finals."

Sanchez-Vicario's victory against Rittner gave her a 14-0 record against the German, which includes seven wins on clay.The victory also let her tie the Fed Cup record for singles wins (45) with Helena Sukova and overall wins (66) with Virginia Wade.

Martinez is playing her first tournament since Wimbledon because of an injured right ankle. She began practice only three weeks ago.

"I'm realistic, I'm not in my best shape," the former Wimbledon champion said. "I was practicing well the last three weeks, but practice is not the same as playing."

On Saturday, Martinez faces Henin, who destroyed her 6-1, 6-0 in the Wimbledon quarterfinals -- Martinez's last match prior to the Fed Cup.

"It's doesn't look too promising," she said.

About 3,000 people attended play Friday -- by far the best attendance so far as the Spanish capital begins a three-day weekend.

Crowds on the first two days of the five-day event have been scant, leaving the 6,000-seat venue mostly empty. The withdrawal of the two-time defending champion United States -- it has five players in the world top 10 -- with security worries has hurt.
