After watching Dr. Schivel turn in his best performance to date despite having to overcome a broken rein during his victory in the Grade 2 Santa Anita Sprint Championship, trainer Mark Glatt is hopeful his lightly raced 3-year-old speedster is ready for yet another forward move when he faces an even more formidable assignment in the $2 million Breeders’ Cup Sprint. The BC Sprint will be run at six furlongs on Nov. 6 at Del Mar.
