Anna Frolova has been added to the start list of Pervenstvo Moskvy, she is therefor back to evaluation for a possible JGP start it seems:

She is not alone in this respect, there are quite a lot of boys from Test Skates on the start list too, so one more chance to prove themselves.
There are several other skaters in KMS rank and about the same age or older in contention?
Registration to the final qualification moment is about to be closed but one probably has to wait for the actual competition to start to learn about the final line up, Sept 2-5.
Tarusina and Vasil'yeva are both MS, Master of Sports rank, so they are fine, but they are by all accounts no real competition for Valiyeva in the Chelyabinsk JGP stage.
Russia has such a deep field in every age group there always is something important at stake in every competition. Nothing is guaranteed, nobody is entitled, you need to proof yourself every single time.
