I think you could describe Tammy's season as great in the first half, getting to #19 in the world, but just average in the second half.
Ai had a bit of a mixed season, but won some good matches.
Iroda aswell could be described as a mixed season, loosing to players you woudn't think she would lose to at all, then she gives Tammy a lesson 6-1 6-3.
Cho had a really good season and will probaly keep improving.
Widjaja had a pretty good year with a title win and should be happy with that
