Cal Cup as BC preps?

[Pedigree Ann]

Two Cal Cup winners come back to win on BC Saturday: BC Sprint winner Dancing in Silks comes off a win the Cal Cup Sprint and the Cal Cup Turf mile winner The Usual Q. T. (dreadful name) wins the Volante H (renamed the Oak Tree Derby, for some reason. Why change a race named for one of Lucky Baldwin's best runners, who is buried on the grounds? Especially for such a generic name. But I digress.) Who would have thought that Cal Cup form could have any relevance at all to the BC races?
