Serena, Azarenka cruise into Rome quarters

Red-hot Serena Williams and former world No. 1 Victoria Azarenka were a pair of easy third-round winners Thursday at the $2.37 million Italian Open, a clay-court French Open tune-up.

The reigning No. 1 Williams dismantled helpless 14th-seeded Slovak Dominika Cibulkova 6-0, 6-1 in only 66 minutes, while the third-seeded Australian Open champion Azarenka was having her way with Ayumi Morita 6-1, 2-0 when the Japanese player retired on Day 4 at Foro Italico.

This year's Aussie Open runner-up Li lost to Maria Sharapova in last year's Rome finale.

Other third-round play saw Romanian Simona Halep upend 13th-seeded Italian crowd favorite Roberta Vinci 6-4, 6-2 and the aforementioned Suarez Navarro whip lucky loser and fellow countrywoman Lourdes Dominguez Lino 6-2, 6-3.
