Greek tennis star Maria Sakkari notched up an amazing win over Angelique Kerber, a player she has never beaten before, to reach the Grampians trophy final four.
This is her first win in three career meetings with Angelique Kerber.
Anett Kontaveit will be her semifinal opponent, after Victoria Azarenka withdrew from their scheduled quarterfinal match due to a back injury.
Jennifer Brady and Ann Li will contest the other semifinal.
No.5 seed Sakkari erased a hefty first-set deficit to oust No.8 seed Kerber of Germany, 6-4, 6-2 and claim her first victory over the former World No.1 on Saturday.
"I have my Greeks here, which feels great!" Sakkari said during her post-match interview on court, thrilling her sturdy number of supporters on Margaret Court Arena. "That’s the first thing I was looking forward to when I come to Australia, so it was great."
"Funnily enough, this is my home tournament," Sakkari added. "I don’t have a professional tournament back home, so as I mentioned, every time I come back to Australia, it feels like I'm at home."
