Following a brief amateur career, Cuevas turned pro while he was still a teenager.He was raised in Mexico City, Mexico among a boxing family.
Although he carried knockout capabilities in either hand, Cuevas was known for his explosive left hook. He captured the Mexican welterweight title in 1975. Following a decision loss to Andy Price, he was matched with Angel Espada for the WBA title in July 1976. Only 18, Cuevas scored an impressive 2nd round TKO for the title to begin a spectacular reign that eventually included 11 successful defenses over the likes of Harold Weston, Randy Shields, and Clyde Gray.
He lost the crown to Tommy "Hitman" Hearns in 1980. Cuevas continued to box, including a loss to Roberto Duran, but never again challenged for a world title. He retired in 1989.
