Trainer Brad Cox, a leading figure in North American thoroughbred racing, is poised for a potential Kentucky Derby triumph nearly five years after his first official win in the event was awarded under unusual circumstances. Cox, who has guided horses to victory in major races including the Dubai World Cup and the Breeders’ Cup Classic, has amassed more than $40 million in earnings since early 2025 and holds nearly 2,900 career wins. However, his status as a Kentucky Derby winner carries a caveat.

In 2021, Medina Spirit, trained by Cox, crossed the finish line first at Churchill Downs but subsequently was disqualified after failing a post-race drug test. This resulted in Mandaloun, also trained by Cox and the runner-up on race day, being declared the official winner almost ten months later. Cox has described the experience as lacking the traditional celebrations and fanfare typically associated with winning the storied race, remarking that there was “no thrill” in learning of the victory by phone months after the event.

Now 46 and a native of Louisville, Cox returns to Churchill Downs with two strong contenders in this year’s Derby—Commandment and Further Ado—raising hopes of securing an undisputed win. Commandment, with a near-perfect record of four wins in five starts, narrowly defeated The Puma and Chief Wallabee at the Florida Derby on March 28. Further Ado posted the fastest recorded speed in the field following an 11-length victory in the Blue Grass Stakes on April 4.

Cox expressed confidence in both horses, stating they are “full of themselves” and expected to deliver their best performances. Although the stable was dealt a setback when Fulleffort was scratched due to a chip in his left hind ankle just days before the Derby, Cox remains optimistic about his chances.

Industry experts have echoed this sentiment. David Aragona, an analyst with Daily Racing Form and an oddsmaker for the New York Racing Association, named Commandment as his top Derby pick, citing the horse’s versatility in race positioning and demonstrated determination in close finishes as key factors for handling the crowded field typical of the Kentucky Derby’s 20-horse lineup.

Meanwhile, retired Hall of Fame jockey and racing analyst Jerry Bailey favors Further Ado, highlighting the horse’s raw speed and tactical versatility. Bailey noted that Further Ado’s jockey will be John Velazquez, a three-time Derby winner whose chance at a fourth victory was thwarted by Medina Spirit’s disqualification five years ago. Cox said selecting Velazquez to ride Further Ado was straightforward, emphasizing the jockey’s expertise navigating the unique challenges of the Derby course.

As the first Saturday in May approaches, Cox looks to secure the Kentucky Derby victory he has long pursued on race day itself, a milestone that has so far eluded him despite the official record.
