Third seed Simona Halep thrashed Carla Suarez Navarro 6-1 6-1 to reach the French Open quarter-finals.
Halep, the 2014 runner-up, is one of the favourites to win the title in Paris and swept aside her 21st-seeded opponent in exactly one hour.
It was the Romanian's first win over Suarez Navarro on clay in six attempts.
She will play either fifth seed Elina Svitolina of Ukraine or qualifier Petra Martic, the world 290 from Croatia, for a place in the semi-finals.
