Youngest jockey to ever win the Kentucky Derby

Alonzo “Lonnie” Clayton made history as the youngest jockey to ever win the Kentucky Derby — at just 15 years old.

In 1892, he rode Azra to victory, becoming part of a generation of African American horsemen who helped shape the early days of the sport.

At a time when Black jockeys were among the most dominant riders in racing, Clayton built a reputation as a skilled and fearless competitor, earning wins in some of the sport’s most important races.

His story is part of a larger legacy — one that speaks to the roots of horse racing, and the people who helped build it, often without recognition.
