In a tweet sent Oct. 22, the Kentucky Public Protection Agency stated that a sample had come back positive for a “Class C” violation from the horses tested on the Sept. 4 race card at Churchill Downs, which was highlighted by the Kentucky Oaks,  one of the top races in North America for 3-year-old fillies.

“The Oaks day samples returned a finding for a class C medication in one (1) primary sample. The KHRC is following its regulatory process in conducting a follow-up investigation of this matter. Accordingly, the names involved will be released at the completion.,” said the Tweet.

The New York Times‘ Joe Drape is reporting that the positive test belongs to GAMINE, who finished third in the Oaks.

The filly Gamine, who tested positive for a banned substance in May, did so again in September after finishing third in the prestigious Kentucky Oaks, according to two people familiar with the results of the drug test who requested anonymity because they were not authorized to discuss the issue publicly.

Gamine is trained by Bob Baffert, a Hall of Famer who is one of the most decorated people in horse racing, but also one who has caught the attention of regulators over the years.

This was Baffert’s 28th drug violation, and his third in six months, according to public records compiled by the Association of Racetrack Commissioners International and the Thoroughbred Regulatory Rulings database maintained by the Jockey Club.
