World number one blazes a trail in Paris
Top seed Dinara Safina continued her impressive form at the French Open with a 6-1 6-0 success over home hope Aravane Rezai.
The Russian came into the fourth-round match having lost just one of her last 18 contests on clay and had dropped only five games during the first three rounds at Roland Garros.
Rezai could do little to halt her opponent's momentum, taking only one game as the world number one cruised to victory in 53 minutes.
The French youngster held her first service game but was blown away thereafter, Safina breaking in the fourth and sixth to secure the first set 6-1.
The second set was even more one-sided, Safina imediately setting the tone by breaking Rezai in the first game before closing it out to love to advance to the quarter-finals.
Safina will face the Victoria Azarenka in the last eight after the Belarussian teenager ended Ana Ivanovic's title defence.
Cibulkova through
Earlier on Sunday, Dominika Cibulkova had become the first woman into the quarter-finals.
The Slovakian, seeded 20th in Paris, saw off Agnes Szavay 6-2 6-4 to reach the last eight of a Grand Slam event for the first time in her fledgling career.
Szavay failed to replicate anything close to her performance in the previous round when she had beaten third seed Venus Williams in fine style.
The Hungarian was comprehensively outwitted by Cibulkova, who completed the win in one hour and 36 minutes.
The 20-year-old will play either Russian Maria Sharapova or China's Li Na in the last eight.
