I haven't found any such thing .....
only place to try is the ITF.
Dinara's next possible junior event Seiko Super Tennis in Osaka in middle of October ( 8th Grade A tourn).
But I don't think she will play juniors again until end of November when its Florida time and the Eddie Herr Champs , Connelly Continental Cup (Team event) Orange Bowl
on the WTA front
Dinara may have a WC and play in $75K Batumi , Moscow and at end of October in $10 Minsk
