Bob Martin
The authority behind the opening line
At Churchill Downs and the Union Plaza, Martin became an influential linemaker in the years before computer-driven odds services.
Learning the trade before Nevada
The Sun’s obituary traces Martin through betting activity in New York and Washington before his move to Las Vegas in 1963. He joined Harry Gordon’s Churchill Downs book. His career bridges the earlier independent betting shop and the sportsbook inside a hotel casino. [1]
Churchill Downs to the Plaza
Martin managed Churchill Downs in the 1960s and early 1970s, then the Union Plaza book. The Sun’s later retrospective identifies him as a leading national oddsmaker of that period. His influence depended on the reputation attached to his numbers, in a market with very different information tools from today’s. [1] [4]
A reputation remembered
Reporting on his March 2001 memorial brought together bookmakers and colleagues from across the city. Their recollections emphasized personal trust as well as skill. Read those tributes as evidence of how his peers regarded him, rather than as a statistical ranking of every bookmaker. [3]
Following the next generation
Sonny Reizner worked under Martin at Churchill Downs. Following that connection leads to the Castaways and its football contests. Following the larger change in the business leads to Roxy Roxborough’s consultancy: a different way to distribute the information that Martin’s contemporaries sought from a respected individual.
