I looked around and couldn’t find an answer to this. I have a horse, Diamond Etched (24710) who is not in the top 20 for the 2yo filly divisions of the Breeders’ Series but if I go to her Upcoming Races page it lists BS races as being able to enter. I presume I should go by the actual BS qualifier list, but I wanted to verify. Also, how are BS qualified horses determined? I have another 2yo who has no stakes runs to her name and has only won 3 of 7 starts but is in the top 20 of her division, whereas Diamond Etched has won 5 of 7 starts including a stakes.
I think Upcoming Races doesn’t take into account the qualifier lists (I hope that if you clicked to enter her it wouldn’t let you 
).
She is not eligible because she was bred by Clover Springs and not nominated for this year (due to CS leaving the game). Her racing performance is thus irrelevant.
Ah, okay. Thanks Shanthi!
