Outsiders to have their day in Paris
After the recent domination of Belgians and Russians and Serbs and Williams, we have an Australia-Italy Grand Slam final completely out of the blue.
Stosur, the 26-year-old from the Gold Coast, is the first Australian woman to reach a major final in 30 years, while the appearance of Schiavone, the 29-year-old from Milan, means Italy is represented in a women's Grand Slam singles final for the first time in history.
Stosur thrashed the volatile fourth seed Jelena Jankovic to add to her previous conquests of Justine Henin and Serena Williams.
The Aussie played well again but what was Jankovic doing?

After losing a miserable first set 6-1, the Serb won the first seven points of the second set, 10 out of the first 11, and looked to have found her form with a series of clean forehands.
But inexplicably, after losing the third point of the third game (leading 2-0, 30-0) she seemed to self-combust for no obvious reason. The familiar complaint to her box, the familiar frustrated gesture with her left hand. Bad news, both.
She didn't win another game in the match and even her normally supportive mother gave up before the final game, leaving her seat and standing in the gangway, departing for good once Stosur moved 30-15 ahead.
What a story if the late blooming Aussie goes on to win from here.
Her record of 11 first-round defeats from her first 22 Grand Slam singles events hardly suggested a major winner of the future.
And her recovery form the debilitating Lyme disease, which has been well documented over the past couple of years here in Paris, provides a human interest for the neutrals on Saturday.
This is her 39th successive Grand Slam event since her debut at the 2000 US Open, but only twice before had she made a quarter-final. A collection of first, second and third-round defeats makes her major championship listing in the media guide instantly skippable.
But congratulations to her - a worthy finalist here in Paris.
It's just a shame she couldn't celebrate properly because she was as stunned as the rest of us when her semi-final opponent, Elena Dementieva, decided to quit at the end of their first set tie-break.
Dementieva had disguised the severity of her calf muscle tear extremely well, fighting hard in a 69-minute set, but the pain was clearly too great.
She debated whether to even take the court, taking a series of pain killers before the match, and afterwards admitted she would have retired even if she had won the set.
It was a shame at the time, and some people were seething in the corridors ("how can you do that in a major semi-final?"), but it must have been agony to abandon a chance of a Grand Slam final without even calling for the trainer.
By the sound of it, the crowd were fortunate to get one competitive set and, in any case, it lasted six minutes more than the one-sided second semi which followed.
