On the first Saturday in May, the marching band will play “My Old Kentucky Home,” and the field will file onto the Churchill Downs main track past the rose-trimmed winner’s circle that is used only one weekend a year. As many as three horses will run in the name of Calumet Farm, which has won a record eight editions of the Kentucky Derby.

But while a winner would add to that history, he would be the first of the group to carry the colors of current Calumet owner Brad Kelley, a deeply private man who assumed control of the historic property five years ago.

Bodemeister and Union Rags were major factors on the 2012 Triple Crown trail, and five years later, both are expected to have starters from their first crops in the Kentucky Derby.

Bodemeister, who finished third on last year’s freshman sire list for WinStar Farm, won the Arkansas Derby before finishing a hard-fought second to I’ll Have Another in both the Kentucky Derby and Preakness Stakes. His first crop is highlighted by Always Dreaming, expected to be among the favorites in the Kentucky Derby after a five-length romp in the Florida Derby.

Unbridled’s Song was a successful stallion throughout his life and has accomplished more posthumously than many stallions do in their whole careers, with two popular champions among his runners in the past four years.

But there is one hole in his résumé that he has a chance to fill next week. Kentucky Derby contender Battalion Runner, from his final crop of foals, represents his best, last chance to sire the winner of a Triple Crown event.

John Oxley remembers his father gathering the family around a tiny radio in his hometown of Tulsa, Okla., to listen to Clem McCarthy’s call of the 1946 Kentucky Derby, where Assault launched his successful quest for the Triple Crown.

The Kentucky Derby’s points system, which replaced graded stakes earnings as the method for sorting out contenders, completed its fifth year of prep races this spring.

The system’s half-decade in existence has provided an interesting snapshot of which stallions were most proficient in siring the archetypical Derby prospect – precocious colts who run on the dirt, consistently win or place in points races, and peak in the key Derby preps during the spring of their 3-year-old season.

Lady Foghorn, who concluded last season with a victory in the Grade 2 Falls City Handicap at Churchill Downs, has been named the Indiana Horse of the Year by the Indiana Thoroughbred Owners and Breeders Association.
