French teenager Tatiana Golovin limped out of her match with Greek Eleni Daniilidou after trailing by a set.

The Czech failed to find any rhythm or consistency, and although she served for the match at 5-4 she dropped her serve to love before taking the tiebreak 7-4.
"I think she played a great match and stepped up her game," said Vaidisova. "I was a little tired today and had a lot of unforced errors but was able to pull it out and that's what co
