A horse trained by Bob Baffert has tested positive for a prohibited medication that is a common ingredient in cough suppressants, adding to a string of post-race positives for the trainer in recent months.

According to a complaint posted on the website of the California Horse Racing Board, the horse, Merneith, tested positive for dextrorphan following a second-place finish in the fourth race at Del Mar on July 25. The positive was confirmed in a split-sample test. The complaint does not list the concentration of the drug found in the horse’s system.

LEXINGTON, Ky. – Owners and breeders of horses competing in the Breeders’ Cup will be allowed on the grounds of Keeneland Racecourse in Lexington during the two-day event on Nov. 6-7, Breeders’ Cup officials confirmed on Tuesday.

According to Jim Gluckson, a spokesman for the Breeders’ Cup, each horse will be assigned six complimentary seats on behalf of its owners for each day of the event, to be distributed by the ownership group. However, Gluckson also said that Breeders’ Cup will “work individually with owners to see if we can accommodate guests beyond that number.”

Two horses that won on the same day at Charles Town Races in West Virginia out of the same barn have been disqualified from their races after the horses tested positive for ingredients in “bath salts,” but the trainers of the horses will not be punished due to a stewards’ finding that the positives were due to contamination.

James C. Brady, a third-generation horseman and banker, died on Thursday at his home in Bedminster, N.J., it was announced Saturday by The Jockey Club, for whom he served in prominent positions for four decades. He was 85.

Two winners of Triple Crown races worked Saturday morning for upcoming Breeders’ Cup races, perhaps even a rematch of their epic match in the Preakness Stakes earlier this month.

Authentic, the Kentucky Derby winner, and Swiss Skydiver, the filly who beat males – including Authentic – in the Preakness, both turned in their penultimate drills in preparation for starts on Nov. 7 at Keeneland.

Leading Breeders’ Cup Mile hope Mo Forza is out of the race with what trainer Peter Miller termed a “minor issue.”

Mo Forza was out of action between January and August but roared back into racing with decisive victories in the Del Mar Mile and on Oct. 2 in the City of Hope Mile. But Mo Forza had not posted a timed workout since his last race and Miller had to pull the plug on hopes for making the BC Mile.

Gamine, a Grade 1-winning 3-year-old filly trained by Bob Baffert, tested positive for a regulated corticosteroid following her third-place finish in the Grade 1 Kentucky Oaks on Sept. 4 at Churchill Downs, Baffert’s attorney said in a statement following the publication of details of the positive test in The New York Times on Thursday night.

England-based trainer Ralph Beckett hasn’t started a Breeders’ Cup runner since the event last was held a Keeneland, in 2015, but Breeders’ Cup officials expect at least one and possibly two Beckett-trained runners in the Juvenile Turf next month.

Beckett, who could not be reached by phone Wednesday, has long mentioned New Mandate as a likely participant in the Juvenile Turf, while Devilwala, who finished fourth at odds of 100-1 Oct. 10 in the Group 1 Dewhurst at Newmarket, also showed up this week on the Breeders’ Cup roll call of possible starters.

The international contingent for the Breeders’ Cup lost several major names in the past week, including ace British sprinter Battaash, who was declared out of the Turf Sprint in favor of freshening him for a 2021 campaign. The connections of other European Turf Sprint candidates, including Group 1 winner Glass Slippers, are still finalizing their plans. However, the race is expected to have some international flair thanks to Team Valor’s comebacking homebred Oleksandra, who is looking to continue a run of long layoffs for Turf Sprint winners.

Trainer Graham Motion participated in his first Breeders’ Cup in 2004 and has had at least one runner in the event each year since winning that year’s Turf with Better Talk Now and running second in the Filly and Mare Turf with Film Maker. Motion’s streak will reach 17 this year with, among others, Mean Mary in the $2 million Breeders’ Cup Filly and Mare Turf on Nov. 7 at Keeneland.

In September 2019, when the Scat Daddy filly finished fifth in her debut on dirt at Laurel Park, Motion said he “did not know she was this kind of filly.”
