( CNN ) -- World No . 2 Caroline Wozniacki hopes to be fit for this year 's second grand slam tournament , the French Open , despite suffering an ankle injury in an American event . The Dane had to retire hurt during her semifinal match against Russian seventh seed Vera Zvonareva in Charleston , South Carolina , on Saturday while trailing 5-2 in the first set . The top seed slipped on the green clay in the sixth game and rolled her ankle , meaning Zvonareva went through to Sunday 's final where she will face Australian Samantha Stosur . Wozniacki , who won the WTA Tour tournament in Ponte Vedra Beach last weekend , told reporters that she hoped to be able to play at Roland Garros when play begins on May 24 . `` I certainly hope so . As it looks right now , it 's not too bad , '' said the 19-year-old , who will have a scan on the injury . `` I was surprised that I could stand on my leg , which was very positive , actually . `` But as soon as I was moving to the sides , it was impossible , so I could n't play . '' Fourth seed Stosur reached the final of the Family Circle Cup with a 6-3 7-6 ( 7-2 ) victory against No . 8 Daniela Hantuchova of Slovakia . Meanwhile , top seed Francesca Schiavone won the Barcelona Ladies ' Open after thrashing fellow Italian Roberta Vinci 6-1 6-1 in just under an hour in Saturday 's final .
