Mauricio Baldivieso, who turns 13 on Wednesday, made his first division debut in Bolivia on the weekend.
Baldivieso was brought on as a substitute for the final nine minutes of Aurora's match away to La Paz, a 1-0 defeat, in the Clausura championship.
Julio Cesar Baldivieso, the boy’s father, a Bolivian 1994 World Cup midfielder and also Aurora’s coach, said: "I'm very proud, he's got a lot of talent."
Baldivieso senior did complain after the match about the rough defending his son received from Henry Alaca that left his son in tears, calling the defender a criminal and slamming the referee for not booking him.
The previous youngest debutant in South American football is believed to have been Peruvian Fernando Garcia, who was just short of his 14th birthday in 2001.
