A statement from his family said Gentry died Sunday in Lexington, where he lived. He also resided in Stuart, Fla.

Proud Clarion ran one of the fastest times in the Derby. Gentry also trained Kauai King as a 2-year-old before the horse went on to win the Kentucky Derby and the Preakness in 1966 under another trainer when Gentry went into private training.

Gentry also trained Graustark, who was undefeated until his last race.

He continued breeding and training until his death.

Gentry's father, also named Loyd, twice rode in the Derby as a jockey before turning to training, and his uncle, Olin Gentry, managed Col. E.R. Bradley's farm.
