Charleston: Australian tennis player Sam Stosur retired with a calf injury from her third-round match at a WTA tour event here in South Carolina. The third seed on Thursday was trailing Canadian qualifier Eugenie Bouchard by a set and was 0-2 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 quarter-final, 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 quarter-final encounter with Caroline Wozniacki.
