I've copied the following from the Ostrava? thread into this new discussion thread:
If the top 2 senior ladies' finishers at U.S. Nationals are sent to L.A. Worlds (and top 3 offered Four Continents), then the next 3 age-eligible seniors will likely be considered for Jr. Worlds. Of the nine U.S. ladies on the Senior Grand Prix this fall, SIX are still ISU Junior age-eligible -- Flatt ('08 JW champ), Zhang ('07 JW champ, '08 JW silver medalist), Wagner ('07 JW bronze medalist), Nagasu ('08 JW bronze medalist, '07 JW silver medalist), Hacker (the only one in this group who has not been to JW before), and even Meissner ('04 JW silver medalist, 4th in '05; she turned 19 after July 1st).
U.S. Junior ladies' medalists who have been selected for Junior Worlds in the same season are much rarer -- they include Nagasu, Zhang & Wagner in 2007, Meissner and Katy Taylor in 2004, and Louann Donovan in 2002.
Four of the five in the JGP Final -- Alexe Gilles, Kristine Musademba, Angela Maxwell and Becky Bereswill -- will compete as seniors in Cleveland.
