ARCADIA, Calif. – There were no major surprises when pre-entries for the $1 million Breeders’ Cup Filly and Mare Sprint were released Wednesday. Unique Bella, the once-beaten filly whose sharp return in the L.A. Woman earlier this month cemented her status as a solid favorite, heads a full field of 14 pre-entered for the seven-furlong race Nov. 4 at Del Mar.
