Statement on mortality review of Hit Zero - Maryland Racing Commission

June 25, 2026

The Maryland Racing Commission has completed its mortality review of Hit Zero, following a sudden fatal medical event after a race on Black-Eyed Susan Day, May 15, 2026, at Laurel Park. The Commission's review included examination of veterinary records—including records from a mandatory pre-race veterinary exam—as well as race and training history, race replay footage, steward reports, regulatory records, and findings from a post-mortem examination conducted by board-certified veterinary pathologists.

The post-mortem examination determined that Hit Zero died as a result of sudden internal bleeding in the chest. The findings are consistent with a sudden failure of blood vessels in the area surrounding the heart, resulting in internal bleeding that could not have been predicted or prevented based on the information available prior to the race. Hit Zero’s pre-race exam completed by a Maryland Racing Commission veterinarian did not indicate any concerns. The full review process found no regulatory violations or safety concerns that contributed to the incident.

While musculoskeletal injuries are more commonly associated with racing fatalities, sudden cardiovascular or internal bleeding events can occur in horses and may arise without warning despite routine veterinary oversight and monitoring.

The Commission recognizes the emotional toll such events have on the individuals connected to Hit Zero and the broader horse racing community. The Commission remains committed to conducting a thorough review of every equine fatality occurring at Maryland racetracks and will continuously evaluate opportunities to strengthen equine safety and welfare.

Based on the findings of the review, no regulatory or operational changes are recommended at this time. The Commission will continue to monitor injury and fatality data and work collaboratively with industry stakeholders, veterinarians, and safety organizations to advance the health and welfare of Maryland's racehorses.
