Meet Deputy, a nineteen-year-old lead outriding horse. Outrider Trey MacGillivray explains that this veteran equine athlete is one of those horses who knows his job and always gets it done. He also is a horse who taught him a lot about outriding when he started. His career on the track saw Deputy win over a hundred thousand dollars, but in the MacGillivray barn, he is the go-to horse for barrels one and two.
