It's like most of the players in the top 20 are in a slump:
Henin- playes a lot below her normal level, she is losing sets for players almost unheard of and got bageled (though it was to Maria when playing superbly, Henin shouldn't get bagled by anyone).
Kuznetsova- Also playing bad at the moment losing to players she should beat sometimes even easly.
Chaketadze- alone from her Paris title her year has been a disaster
Venus- didn't do much this year- losing in AO QF in a bad match to Ivanovic and to Dominika at Doha.
Bartoli- Playing very bad, if she will continue like this I don't see her in the top 15 after wimbledon.
Serena- though she played only at the AO she didn't show a lot of her greatness.
And that is only in the top 10. from 11-20 you got Dementieva (though she looked goot yesterday def Schnyder), Schnyder, Petrova, Golovin, Safina (though she looked like she got back on track in Doha), Szavay, Peer and Bammer.
What happened to the top 20?
