MGM Resorts International said Tuesday it was shutting down its Yonkers Raceway outside New York City after a worker with the Standardbred Owners Association tested positive for the coronavirus and had passed away. The harness track, which the Las Vegas-based company acquired last year along with the adjacent Empire City Casino, was closed Tuesday afternoon and employees who worked in the immediate area as the affected worker were asked to self-quarantine. A spokesman for MGM said the Empire City Casino was not affected by the closure since the building is separate from the racetrack.
