One Master was scratched from the Breeders’ Cup Mile on Thursday morning because of persistently elevated muscle enzymes. The elevated enzyme levels can produce a condition know as tying up, a locking of muscles that restricts movement, and that is what happened to One Master the first day she trained at Keeneland this week, according to trainer William Haggas. “Her first day on the track she tied up – her muscle enzymes were very high,” Haggas said. “We gave her fluids, which is normal treatment. They were still high the following day, and we just walked her in the barn. This morning, she had blood taken, we gave her a trot on the track, but her muscle enzymes still were raised too much for her to show her best. I wanted to give her every chance to get better, but I don’t want to run her with any risk at all.” :: Play the Breeders’ Cup with DRF!

Six-year-old One Master, bred and owned by the Lael Stables of Roy and Gretchen Jackson, has an invitation to the Hong Kong Mile in December, but Haggas termed a trip there “very unlikely,” suggesting that One Master could be retired to become a broodmare. “I want to get her home [to England] and see what she’s like,” he said. One Master finished fifth in the 2018 BC Mile and is, remarkably, a three-time winner of the seven-furlong Group 1 Prix de la Foret, part of the Prix de l’Arc de Triomphe undercard. By Fastnet Rock out of Enticing, by Pivotal, the mare is a seven-time winner with a $1.21 million bankroll.
