Charleston, April 18:

Serena Williams set up a quarter-final match against Maria Sharapova in the Family Circle Cup, overcoming a sprained ankle and sluggish performance to beat Katarina Srebotnik 4-6, 6-4, 6-3 on Thursday.

The second-seeded Sharapova beat Taiana Perebiynis of the Ukraine 7-5, 6-2. The Russian star, coming off her first clay-court title last week at Amelie Island, is looking for her fourth tournament victory of the year.

Williams, a two-time tournament winner this year, slipped and fell near the net when trailing 4-3 in the first set. She was unsure how the injury might affect her Friday against Sharapova.

Meanwhile, defending champion Jelena Jankovic of Serbia, the top seed, had an easier time, defeating unseeded Russian Anastasia Rodionova 6-0, 6-2 in less than an hour.

In the quarter-finals, Jankovic will face ninth-seeded Vera Zvonareva, a 6-4, 4-6, 6-1 winner over sixth-seeded Marion Bartoli of France.

Tenth-seeded Agnes Szavay beat eighth-seeded Dinara Safina 6-2, 7-5, and will face Alize Cornet in the quarterfinals. Cornet beat Sorana Cirstea 6-1, 7-5. Fourth-seeded Elena Dementieva also advanced, beating 13th-seeded Victoria Azarenka 6-4, 7-5.
