In 2007, Kruytbosch's call of the Derby was carried live on ESPN Radio. Born in Moscow, Idaho, Kruytbosch began announcing horse races on the Arizona County Fair circuit while attending the University of Arizona Race Track Industry Program. After college he began announcing both Thoroughbred and Quarter Horse racing throughout the southwest. He called the world's richest Quarter Horse race, the All American Futurity at Ruidoso Downs, six times. In 1996 he was named track announcer at Hollywood Park Racetrack, then in 1999 he moved on to Churchill Downs in Louisville, Kentucky. During the winter months, Kruytbosch returned to Arizona to call races at Turf Paradise.
