CHARLESTON, S.C. (AP) -- U.S. Open champion Samantha Stosur won the final five games of the rain-delayed match for a 6-3, 4-6, 6-2 victory over Galina Voskoboeva at the Family Circle Cup on Friday.
The second-seeded Stosur returned to play after severe storms swept through the area Thursday night. The washout means double duty for Stosur, who will play Venus Williams in the quarterfinals later Friday.
Stosur is the highest seed left in the tournament following the withdrawal of Poland's Agnieszka Radwanska, who won the Sony Ericsson Open last week.
She led 3-1 in the second set before Voskoboeva rallied to force a third set.
Venus' sister Serena Williams also has a quarterfinal match Friday. Should the sisters win, it would mean a semifinal showdown between Venus and Serena on Saturday.
