Trevor as Paul has said if you want the whole "shootin match" I think you'll need to open an account on the USTA's Pathways system. I don't have an account so I cant tell you exactly whats available there.
I think though what your probably after is data for promotional material for your fillies at the sale so this might help

SBSW does have remarkably good stats so far for fillies, almost 2:1 classic winners as opposed to colts, though it is of course for only one crop so far. If you are a believer in "X-factor" you could mount a pretty strong case for it here. You could also mount a case for "X-factor" in regards to SBSW best colt as well.
You might also want to use this-doesn't get as much recognition here as it probably should
