Safina rolls, Ivanovic out at French Open

PARIS, May 31 (UPI) -- Top-ranked Dinara Safina rolled to another victory but defending champion Ana Ivanovic was ousted Sunday in fourth-round action at the French Open in Paris.

Safina routed Aravane Rezai 6-1, 6-0 in 53 minutes. She's lost just five games -- one total in her second sets -- in four matches. Safina is 18-1 since taking over the world No. 1 ranking.

She faced two break points against Rezai and won two-thirds of the points in the match.

Also Sunday, ninth-seeded Victoria Azarenka took out Ivanovic 6-2, 6-3; Maria Sharapova continued her comeback from shoulder surgery with a 6-4, 0-6, 6-4 win over 25th-seeded Na Li; and No. 20-seeded Dominika Cibulkova bested Agnes Szavay 6-2, 6-4.

Azarenka had the advantage on Ivanovic, who was seeded eighth, throughout the match, breaking the defending titlist's serve six times while getting 81 percent of her first serves in. Azarenka draws Safina in the quarterfinals.

Cibulkova and Sharapova will also meet in the quarters. Cibulkova, who won 66 points on the day, was helped by Szavay's 44 unforced errors.

Sharapova, playing in her second tournament since missing about nine months of play with a shoulder injury, had her fourth consecutive three-set match and took fewer points (86-78) than Na in the match.
