Bill Mott and son Riley Mott face off in Kentucky Derby 152 showdown

Bill Mott and his son Riley will walk into Churchill Downs on opposite sides of one of Derby week’s most unusual matchups, with a father and son each carrying live horses into Kentucky Derby 152 and no room for sentiment once the gates open.

Bill Mott will send out Chief Wallabee in the 152nd running of the Kentucky Derby on May 2 at Churchill Downs in Louisville, Kentucky, while Riley Mott will make his first Derby appearance as a trainer with Albus and Incredibolt. It is a rare family collision in a sport where bloodlines, barns and business often overlap, but the Derby puts the Motts’ shared history under a brighter light than either man normally sees. Bill Mott has already won the race with Country House in 2019 and Sovereignty in 2025, and he arrived at this Derby trying to become the first trainer since Bob Baffert in 1997 and 1998 to win it in consecutive years.

Riley Mott’s arrival adds the sharper edge to the storyline. Churchill Downs noted that Bill Mott saddled his first Derby starter in 1984, before Riley was born, making the son’s debut feel like both a milestone and a continuation of a career that has been part of his life since childhood. Riley said his first Derby memory was watching Smarty Jones win in 2004, and now he will have a horse in the field himself, with Albus already secure after winning the Virginia Derby at Colonial Downs on March 15, 2026. Albus earned 100 qualifying points in that victory, which stamped his ticket to Louisville.

The Derby itself remains as unforgiving as ever. Churchill Downs’ study guide said 24 horses entered the 2026 Kentucky Derby, with four on the also-eligible list, a reminder that simply getting to the starting gate is a victory over injuries, points-race pressure, and late changes. The race carries a $5 million purse, and every horse in the field enters with a different story, but few have one as personal as this.

Bill Mott’s standing only heightens the tension. The National Museum of Racing and Hall of Fame says he has won 16 Breeders’ Cup races, a résumé that already places him among the sport’s defining trainers. Riley is still building his own name, but on Derby day the two Motts will be measured in the same race, on the same stage, with one result that will be remembered both as a sporting outcome and as a family moment.
