BetNose sniffs out the best odds on tomorrows semi finals at Wimbledon. See all the latest Wimbledon Women 2009 Odds.

Should you be expecting an upset at SW19 tomorrow, bookie Paddy Power is offering 17/1 that Russians Dinara Safina and Elena Dementieva beat the seemingly unstoppable Williams sisters at Wimbledon.

When in the form that Serena and Venus have been in the last two weeks there are very few players that can topple them and that is reflected in the semi-final betting with Venus and Serena just 15/8 to win both their matches in straight sets.

Venus odds to beat Safina are is 2/9 whilst sister Serena odds are 1/5 to knockout Dementieva. However the bookie can’t split the Williams sisters in the outright betting, making both Serena and Venus 11/10 to win the Venus Rosewater Dish. Safina, who has yet to win a Grand Slam despite her world number one status, is 9/1 with Dementieva the 12/1 outsider.

No woman seems able to come close to toppling the Williams sisters at SW19 – and the two Russians they are facing in the semi-finals certainly both have question marks over their bottle to rise to such a big occasion.
