The home crowd were silenced by a ruthless opening set from the second seed.

Boisson briefly raised the French fans from their slumber by breaking back in the second set, only to immediately surrender it straight back.

Gauff clinically finished the job after just 69 minutes on court to book her spot in a second French Open final.

"When you guys were chanting her name, I was thinking my name," Gauff told the crowd in her on-court interview.

"Obviously there's still a lot of work to do, but for now I'll enjoy this one and then prepare for the final tomorrow."

The 21-year-old suffered an emotional defeat by Swiatek in the 2022 final, but will believe she can finally win the tournament in which she has made at least the quarter-finals in five straight editions.

Boisson had been hoping to become only the second Frenchwoman to win the title in the Open era after Mary Pierce, but went out in a blaze of 33 unforced errors.

"Of course I'm really disappointed today, because obviously I wanted to go further than this semi-final, but I'm just going to take the time to digest this," said the 22-year-old.

She will climb into the world's top 70 next week and has added 690,000 euros ($789,536) to her previous career prize money of $148,009.
