On 19 July 2009, striker Mauricio Baldivieso became the youngest professional player in South American history, making his debut three days short of his thirteenth birthday.
Born in Cochabamba, Bolivia on 22 July 1996, he joined the youth side of his hometown team, Club Aurora, in 2007. After Aurora won the Bolivian Clausura in 2008, the manager, Julio César Baldivieso, who also happened to be Mauricio's father, called him into the first team for the following season.
His record-breaking debut came in a league match against La Paz, with Baldivieso appearing as a late substitute. He had enough time to become involved in some fireworks, though, receiving a painful challenge from an opponent that started a brawl between the two teams, though he managed to finish the match.
Baldivieso remained with Aurora for three seasons, but made only one more league appearance. In 2012, he transferred to Real Potosí, which by that time was also managed by his father. He currently plays for Club San José.
