Fifth seed Elena Dementieva swept into the French Open quarter-finals here on Sunday with an emphatic 6-1, 6-3 victory over South African qualifier Chanelle Scheepers.
The Russian, who had struggled to complete her third-round win over Aleksandra Wozniak due to a calf injury, won in 74 minutes and will meet either Venus Williams or Nadia Petrova for a place in the semi-finals.
Play was due to resume later on Sunday in the third-round match between four-time champion Justine Henin and former world number one Maria Sharapova, after play was suspended at one set all amid fading light on Saturday.
Henin, playing at Roland Garros for the first time since 2007 following her temporary retirement, took the first set 6-2, with Sharapova levelling the match by winning the second 6-3.
The winner will face Australian seventh seed Samantha Stosur for a place in the last eight.
Dementieva and Scheepers, the world number 133, exchanged breaks in the opening two games before Dementieva broke again twice, opening up a 4-1 lead with a powerful forehand return winner that left Scheepers floundering.
Dementieva, who wore bandages on both calves, secured the first set when Scheepers double-faulted and captured the decisive break in the second set when the South African looped a forehand long.
Maria Kirilenko, the 30th seed who beat defending champion Svetlana Kuznetsova in round three, was aiming to join her compatriot Dementieva in the quarter-finals when she tackled Italian 17th seed Francesca Schiavone.
Second seed Williams is due on court against Russian 19th seed Petrova later, while Danish third seed Caroline Wozniacki is set to face Italy's Flavia Pennetta, the 14th seed.
