Juddmonte homebred Mizzen Mast, a Grade 1 winner who went on to a long and successful stallion career for that outfit, was euthanized in late summer due to the cumulative effects of old age. The Cozzene horse, who had been pensioned following the 2021 breeding season, was 27.
“It wasn’t any [one thing], it was just more of an amalgamation of a bunch of things,” Juddmonte manager Garrett O’Rourke said. “They’re never easy decisions, but they’re easier when the horse is telling you, ‘Look, I’m ready.’”
