Coco Gauff came from a set down to defeat Madison Keys in a scrappy all-American quarter-final at Roland Garros, winning 6-7 (6), 6-4, 6-1 on Wednesday.
The second seed recovered from a nervy opening set filled with errors to take control in the second and third, eventually sealing the match with a break to love.
The contest featured 14 double-faults and 101 unforced errors, as both players struggled with rhythm and nerves.
Gauff, the 2022 finalist, now awaits the winner of the last quarter-final between teenager Mirra Andreeva and French wildcard Lois Boisson.
She is bidding to reach her second French Open final and improve on last year’s semi-final exit.
After losing a tight first set in a tie-break despite holding a set point, Gauff raised her level just enough.
Keys briefly rallied in the second but couldn’t keep up as the 2023 US Open champion settled into a more consistent groove in the decider.
