3-year-old Bayview Drive, trained by Jeff Mullins and owned by Cellist Racing, is dead after breaking down in yesterday’s 10th race at Del Mar. He is the 13th horse to die at that storied track in the past month. In his penultimate start on July 26th – the one that saw J Kat crumple – Bayview finished 10th of 11. Oh, and by the way, this kill came on the Polytrack. What to blame it on now?
