Clancy then returned the favour with three clean block winners to snuff out the challenge, to the dismay of the pro-Swiss crowd assembled under the glowing Eiffel Tower.

The Australian's side-out game was exquisite, the pair disarming serves and wrong-footing the Swiss duo with savvy net play and winning several points they had no right to with desperate defence.

"So proud of how we really stayed true and trusted our game, even though things didn't always feel perfect," Clancy said.

"I'm just so happy that Mariafe stuck by me while I was trying to get myself back into the game.

"That's what got us the win, really."

Asked of her early service struggles, Kingaroy product Clancy was blunt.

"It's a great question, I think i just was a pussy," she said.

"It happens, big moments.

"I still stayed patient; you can't be perfect all the time and it's won on side out (receiving points) so we did what we had to do.

"I'm just proud to deliver in these moments and lean into the pressure."

Artacho del Solar said there was never any doubt Clancy would snap out of her funk.

"That's what teamwork is; in those pressure situations we made big plays and T was huge at the net."

The pair broke a 21-year medal drought when they made the final in Tokyo and are the only pair to return intact to the tournament that was played in Japan three years ago.

Gold in Paris would elevate them above Australia's golden pair of the sand, Kerri Pottharst and Natalie Cook, who followed up bronze in Atlanta with gold in Sydney.

Clancy and Artacho del Solar will play the winner of Brazil and Latvia for a place in the final.
