Angelique Kerber ended the French presence in the singles` draws at Roland Garros when she saw off seventh seed Caroline Garcia 6-2 6-3 in the fourth round on Monday.
The German former world number one, seeded 12th, played from the back of the court throughout the match, making it impossible for her 24-year-old opponent to develop her attacking game.
Double Grand Slam champion Kerber will next face world number one Simona Halep after the Romanian demolished Belgian Elise Mertens 6-2 6-1.
Kerber only hit 11 winners but Garcia made 36 unforced errors, meaning the German was never under too much pressure.
Garcia had reached two semi-finals in top-tier events on clay this season, but in front of her home fans on Court Suzanne Lenglen, she was unable to produce her best tennis.
The Frenchwoman briefly threatened a comeback when she pulled a break back for 5-3 after saving four match points, but then sent a routine forehand wide on the fifth match point in the following game.
"I`m happy to be through, she has played really well in the last few months," Kerber said of Garcia, who had reached the quarter-finals last year.
All of the French players in the men`s singles draw were knocked out of the tournament before reaching the fourth round.
