Says on the site it starts on the 11th. I assumed that meant the tournament proper.
says that qualifying starts tomorrow, some main draw matches are on Sunday.
It's a bizarre bit of scheduling though, never known a draw to be made so close to the start of the even proper. Usually there's at least a full day in between.
I've said it before, I wish the ATP would make the various tournament websites state when their draws are made. It can't be hard, surely?
