At the 1903 dispersal sale of Belmont's stable, Masterman was purchased by John Boden for $2,500. Masterman was later given to the Canadian Breeding Bureau by Boden in September 1908 for use as a sire for cavalry horses. Masterman was euthanized in June 1911 after breaking a leg at a contract farm in Petite Cote, Quebec where he was being stabled.
