The California Horse Racing Board lists on their website that four horses associated with the Del Mar Racetrack -- Night Girl, Munny One, Show Your Cards, and Miss Sugar Hill -- have died.
However, according to Mac McBride, Media Coordinator at Del Mar Racing, only three horses died at Del Mar. The fourth horse listed, Show Your Cards, "actually died at the veterinary office at San Luis Rey Training Center and was not a horse related to Del Mar," McBride said.
"The horse is listed as Del Mar related, because it is the 'active meet' taking place closest to San Luis Rey, so [Del Mar] 'collects' that statistic," McBride added.

Citing The Jockey Club's Equine Inquiry Database, Del Mar Racetrack claims to be the safest major racetrack in North America, mainly "due to a series of equine health and safety reforms and veterinary monitoring protocols," said McBride.
