MOSCOW, April 5 (R-Sport) – Sam Stosur retired with a calf injury Friday from her third-round match at a WTA tour event in Charleston, South Carolina.
The Australian third seed was trailing Canadian qualifier Eugenie Bouchard by a set and was 2-0 down in the second when she felt she couldn't go on.
“I was really excited to get out there and I felt like I played really well - it's unfortunate that she had to retire,” Bouchard said on the WTA website.
In the quarterfinal, the 19 year old will face ninth seed Jelena Jankovic, who breezed past local youngster Jessica Pegula.
Elsewhere, Swiss world No. 63 Stefanie Voegele snatched a comeback 3-6, 6-1, 6-3 win over 10th seed Julia Goerges to book a quarterfinal encounter with Caroline Wozniacki.
The second seed Dane didn’t have to uncover her racket on Thursday, as her third-round opponent Andrea Petkovic withdrew with a calf injury.
The Charleston tournament, known for sponsorship reasons as the Family Circle Cup, is the first WTA clay event of the season and has a prize fund of $750,000.
