Sixth-seeded Myskina destroyed Jennifer Capriati's hopes of a second Roland Garros crown, to add to her 2001 title, with a 61-minute 6-2, 6-2 demolition of the American seventh seed.

Shortly beforehand, fellow Muscovite Dementieva, the ninth seed, won a poor quality, error-strewn semi-final 6-0, 7-5 against Argentinian 14th seed Paola Suarez.

Their wins will guarantee a first ever Russian women's champion in Saturday's final after two previous failed attempts in the 107-year history of the event.

Olga Morozova lost to Chris Evert in 1974 while Natasha Zvereva was humiliated 6-0, 6-0 by Steffi Graf in 1988.

Myskina was a picture of cool control and concentration as her all-court game proved too much for 28-year-old Capriati who was on one of her distracted, bad-tempered days.

Yet the stage had been set for the 2001 champion with her own defeat of Serena Williams in the quarter-finals, and the demise of Venus Williams, Amelie Mauresmo, Lindsay Davenport and Justine Henin-Hardenne.

"Maybe there was too much hype for that match and I couldn't focus on the match today," said Capriati.

"It was just a bad day today. She was serving at 50mph and normnally I would hit winners off them but it's very hard when you have to generate all the pace.

"Normally, she plays a hard-hitting baseline game but today she tried something different and I was thrown off rhythm."

For Myskina it will be a first appearance in a Grand Slam final confirming her arrival amongst the elite of women's tennis after steady progress up the rankings over the last five years.

For Capriati there will be despair at missing out on a golden opportunity to add to the three Grand Slam titles she has already and at 28 years, one of the oldest players on the tour, she may never again have a better chance.

Dementieva had knocked out French hope Amelie Mauresmo in the quarter-finals and admitted she feared the crowd may have been against her as a result on Thursday.

"I thought the people would not forgive me for it," said the blonde Russian.

"It wasn't the case but it would still be great to win the final so that the crowd will not be angry over me beating Amelie."

The Russian was also relieved to have her career back on track after failing to live up to expectations after taking an Olympic silver medal as well making the US Open semi-finals in 2000.

"That was a good year, unbelievable. But I couldn't handle the pressure of so many people expecting me to do better," said Dementieva who will be chasing her fourth career title on Saturday.
