Horse Tragically Passes Away After Fall at Santa Anita’s Derby Day

Eighth Horse Dies at Santa Anita Derby, Raising Safety Concerns

A 3-year-old filly, Cosmic Heat, died following a fall during a race at the prestigious Santa Anita Derby on Saturday. This marks the eighth horse lost to racing or training injuries at the Arcadia track this year, according to state horse racing officials.

The incident occurred when Cosmic Heat fell while navigating the downhill track’s dirt crossing during the day’s first race. According to the official race chart, she "dropped well off the pace in the early, saved ground around the turn, jumped then fell crossing onto the dirt and was transported off the track via equine ambulance." She was later euthanized, as confirmed by California Horse Racing Board spokesman Mike Marten.

In her brief racing career, Cosmic Heat participated in six races, achieving one first-place finish. The Santa Anita Derby, known as a premier West Coast qualifier for the Kentucky Derby, is a Grade I stakes race that typically features a $500,000 purse, run over a distance of 1 1/8 miles on dirt.

The troubling trend of horse fatalities at Santa Anita extends beyond this year, with previous years recording 12 racing and training deaths in 2025, 14 in 2024, 17 in 2023, 12 in 2022, 19 in 2021, and 16 in 2020.

These statistics represent a significant decrease compared to 2019, when 42 horses died, triggering widespread scrutiny over safety practices in the sport and prompting attention from state lawmakers. In response to the controversy, several reforms, including drug regulations and increased veterinary oversight, were implemented to enhance safety at the venue.

Martha Sullivan, a representative from Kill Racing Not Horses, expressed her discontent, stating, "No legitimate sport would tolerate these deaths of its athletes in just one state, California, not to mention in a sole venue: Santa Anita Park."

Contrarily, Amy Zimmerman, Santa Anita’s senior vice president and executive producer, defended the track’s safety record, claiming a 99.985% safety rate, which she characterized as "unrivaled among tracks with similar racing and training dates." Zimmerman noted, "Last year’s national fatality rate average as reported by the Horseracing Integrity and Safety Authority is 1.0 out of 1,000 starters, whereas Santa Anita Park’s was 0.148 out of 1,000."
