Bobo Brazil
In 1972, Pampero Firpo captured the NWA United States Heavyweight Championship (Detroit version) twice after defeating Bobo Brazil on both occasions - on August 12 and October 28, respectively. Both title reigns were ended by Bobo Brazil in return matches with the championship on the line. Firpo would go on to win the championship one more time on July 17, 1976 from then 9-time NWA United States Heavyweight Champion The Sheik. Firpo would hold onto the championship until October 16, 1976 when he lost it to Don Kent. Firpo was a mainstay in Detroit for the Big Time Wrestling promotion alongside The Sheik and Bobo Brazil.
