I am not going to get involved today, but have a little news and gossip to pass on.
Safina and Zvonareva both collected minor injuries in their quarter final wins and withdrew from their respective doubles matches. I would advise caution if considering a bet.
In the other semi, I thought Venus at 2.10 was backable against Jankovic, but heard a rumour that she might also not be 100%, unable to confirm that, but it is enough to put me off. Also noted that Unibet, who's tennis odds are normally pretty good, pushed out the American to offer the top quote. So either the information is correct, or they have heard the same as me.
