Perth: Kristina Mladenovic defeated World Number one Ashleigh Barty in three sets to hand over France a 2-1 lead over Australia in the Fed Cup final on Sunday and inch them closer to a first title since 2003.
Barty had earlier been in scintillating form, thrashing Caroline Garcia 6-0, 6-0 on Saturday after winning the WTA Finals in China last weekend.
Barty comfortably took the first set, however, 40th-ranked Mladenovic toppled the Australian in the next two sets to emerge victorious 2-6, 6-4, 7-6 (7/1) at a packed Perth Arena.
"It's hard to speak," said an emotional Mladenovic afterwards as the tears flowed.
"We (the team) kept on fighting for every point and that's the way I like to play my tennis."
Ajla Tomljanovic, who was crushed 6-1, 6-1 by Mladenovic in the first singles rubber, will play the experienced Pauline Parmentier later.
If Australia win that one, the final will go to a deciding doubles match in which Barty and Samantha Stosur are scheduled to play Mladenovic and Garcia.
Australia are targeting an eighth title and first in 45 years, while France are seeking a third, and their first since 2003.
