From 1888 until 1961, Houston's professional baseball club was the minor league Houston Buffaloes. Although expansion from the National League eventually brought an MLB team to Texas in 1962, Houston officials had been making efforts to do so for years prior. There were four men chiefly responsible for bringing Major League Baseball to Houston: George Kirksey and Craig Cullinan, who had led a futile attempt to purchase the St. Louis Cardinals in 1952; R.E. "Bob" Smith, a prominent oilman and real estate magnate in Houston who was brought in for his financial resources; and Judge Roy Hofheinz, a former Mayor of Houston and Harris County Judge who was recruited for his salesmanship and political style. They formed the Houston Sports Association as their vehicle for attaining a big league franchise for the city of Houston.
