The four-year-old horse Sandman has been retired from racing following a final career appearance on Oct. 4. Co-owner Griffin Johnson announced the retirement on Oct. 7, confirming the horse will head to stud in 2027.

Why it matters

Sandman concludes his racing tenure as a notable performer on the Kentucky Derby trail, headlined by a significant victory in the G1 Arkansas Derby. His transition to the breeding shed marks the end of a career that saw him compete against elite competition across 15 total races.
