Bailey vs. Azeri

[miraja2]

Off the top of my head I would have to rank her as the top filly/mare in that division of THIS decade, but as others have pointed out, this has been a weak decade for that division.
If you went back to the 90s and matched her against a horse like Inside Information, I think Azeri would most likely be outclassed.
And the 80s were simply an exceptional decade for fillies and mares on the dirt. Of all of them I would personally go with Personal Ensign, but a strong case could be made for a number of them from that decade.
