'The win of her life!' - The moment Sakkari stunned Swiatek at Roland Garros
Iga Swiatek was earlier dumped out at the hands of emerging contender Maria Sakkari, who is having a fine tournament at Roland-Garros, and who has become the favourite to lift the trophy.
She will be expected to beat Barbora Krejcikova, but this 2021 French Open has been anything but predictable so far.
In the day's other singles match, the other women's finalist will also be decided. Russia's Anastasia Pavlyuchenkova is the oldest player left in the competition at 29, and she will face Slovenia's Tarama Zidansek on Thursday afternoon in Paris.
Anglophone duo Desirae Krawczyk and Joe Salisbury team up together for the mixed doubles final. Briton Salisbury is a doubles specialist with a career-high ranking of three last year. He and his American partner will be facing two Russians: Elena Vesnina and Aslan Karatsev.
