Out of the russians inside the top 20 which 1 will be first to start dropping(by that i mean losing alot and gradually fall out top 20 - 30). I would say Petrova.
Certainly not Lena D, because Elena has already been out of top 20 (remember last year)
I would say Petrova as well, cauz she isn't that good, on a good day well, she can give the toppers a hard time, but really beaten toppers in good shape she hasn't done.. (Serena Amelia Island wasn't in good shape)
Sharapova......... I know you will all disagree with me, but this is my opinion
I like Sharapova but I think that wimbledon was just a great week for her
She will lost o Miskyna in two sets, she might get 4 games
