PARIS — Dinara Safina shanked shots, squandered chances, screamed profanities at herself and still won, setting up an all-Russian final at French Open.

The top-ranked Safina beat Dominika Cibulkova of Slovakia 6-3, 6-3 in the semifinals Thursday and needs one more win for her first Grand Slam title.

On Saturday, she'll face No. 7-seeded Svetlana Kuznetsova, who beat Samantha Stosur of Australia, 6-4, 6-7 (5), 6-3.

The combustible Safina won despite seven double-faults. Twice in one game, her shots landed short of the net.

"I'm trying to control my emotions," she said. "I'm not playing my best, but still it's not easy to beat me."

Safina was runner-up to Ana Ivanovic last year at Roland Garros, and lost this year's Australian Open final to Serena Williams. Safina has an 8-5 record against Kuznetsova, and they split two meetings in finals last month.

"I really want to win this tournament," Safina said. "I had a very good experience last year, and I hope to do better this year. I still have a match to play, and I will give everything I've got."

The all-Russian final will be the second at Roland Garros in five years. Anastasia Myskina beat Elena Dementieva for the 2004 title.

Like Safina, Kuznetsova was playing a first-time Grand Slam semifinalist. Coming off a grueling win Wednesday over Serena Williams, Kuznetsova missed a chance at a straight-sets victory, allowing Stosur to overcome a 5-2 deficit in the tiebreaker.

Kuznetsova regrouped and held every service game in the final set. The 2004 U.S. Open champion is bidding for her second major title.

In the men's semifinals Friday, Roger Federer will try to move a step closer to a career Grand Slam and 14th major title, which would tie Pete Sampras' record. He's 5-0 against his opponent, 6-foot-6 Argentine Juan Martin del Potro.

No. 23-seeded Robin Soderling will look to continue his improbable run against No. 12 Fernando Gonzalez. Soderling reached beyond the third round at a Grand Slam tournament for the first time. Gonzalez is the first Chilean since 1960 to advance to the Roland Garros semifinals.

Safina's ranking has drawn criticism because she has yet to win a major. But in the four tournaments since she climbed to No. 1 in April, she's 20-1 with two titles, a runner-up finish and the strong showing at Roland Garros, where she has lost only one set.

"Since I became No. 1, I'm playing finals and winning the titles," she said. "So how much more proof I need to give the people that I think I deserve that spot?"

Her brother, Marat Safin, is a former No. 1 and two-time Grand Slam champion.

The family's notorious temper was evident in the semifinal. At least twice Safina screamed a vulgarity at herself in English that TV microphones picked up, and an announcer apologized to the European audience.

Her language was cleaner when she shanked a backhand into the dirt at her feet.

"That was a great shot," she said.

Later in the same game, Safina misfired so badly on a first serve that she drove the ball into the clay in front of the net. She held anyway for a 4-2 lead in the second set.

"It wasn't an easy match," she said. "I have to be much more dominant on the court."

Safina kissed the corner with a forehand winner to reach match point and closed out the victory when Cibulkova put a backhand in the net.

The match was played from behind the baseline, and it was into the seventh game before either played attempted a volley. The 5-3 Cibulkova was at a disadvantage in rallies because she often had to hit the ball above eye level, while high-kicking shots were right in the 5-11½ Safina's wheelhouse.

"I was planning to serve better, and to make pressure with the return," Cibulkova said. "But today I was just standing so, so far from the baseline, and I couldn't do anything."

On a sunny, cool afternoon, Safina started slowly. She fell behind 2-love, then began to find the range and won five consecutive games. She struggled to close the set, sailing returns long on three successive set points, but converted on the fourth try with a booming forehand.

A lob winner over Cibulkova helped Safina earn the first break of the second set for a 3-2 lead, and she secured the victory despite her fitful moments. Safina finished with 24 winners, while her opponent had 11 winners and 21 unforced errors.
