A bit of late breaking news:

Tatiana Golovin from France, the 5th seed, also moved into the quarter-finals beating the unseeded Rika Fujiwara of Japan 6-4 6-4, after aggravating her injured right ankle in practice yesterday.

“Today was really tough,” said Golovin. “My right ankle is really bad, plus my foot is sore, so I couldn’t even put my shoe on this morning. Today was just a really painful match.”


I had heard Golovin was struggling via some French news links but this confirms her status. Never an idea to expressly bet against injured players but I certainly wouldn't bet on her.
