Lisicki retires just before playing leaving Bouchard and Stosur the favourite to win in Osaka

Tough luck for the tournament organizers as Jelena Jankovic and Sabine Lisicki (the top 2 seeds) retire for the same reason:  left hip injury.

Jelena  was injured  during the final in Tokyo lost to Serena Williams; Sabine managed to play the first match but then she really had to pull out.

This leaves 2 big favourite for the tournaments: Genie Bouchard and Sam Stosur.

Genie is in great form to have conceded only 7 games in the first 2 matches.  Sam dismissed Johanna Larsson and (future tennis star) Belinda Bencic with the same result: 6-4 6-2.
