Early life and amateur career
Castaño started boxing at 11, trained by his father Carlos, who was also a professional boxer. Castaño won a South American Games gold medal and tallied a 181-5-5 record as an amateur, with wins over Errol Spence and Esquiva Falcão. Castaño participated in the 2009 World Amateur Boxing Championships, winning his first two bout before losing to Jack Culcay-Keth. He also represented Argentina in the World Series of Boxing. Castaño accumulated a 3-0 record in the World Series, including a famous win over Serhiy Derevianchenko, who had previously been unbeaten in the competition.
Castaño made his professional debut on September 2012, months after his win over Derevianchenko. He beat Alejandro Antonio Dominguez with a round 4 technical knockout at Luna Park. Castaño won his first 8 fights, 7 by way of knockout, before being sidelined due to an arrhytmia which caused several medical complications. After recovering, Castaño relocated to the United States. Castaño maintained his winning streak, winning four fights over the course of a year while fighting out of the U.S.
On November 2016, Castaño fought Emmanuel de Jesús for the WBA super welterweight interim title. After knocking De Jesús down on round 1 with a flurry of punches, Castaño went down at the beginning of round 2, following a cross from De Jesús. Castaño survived the round and as the fight went on, De Jesús started slowing down. Castaño eventually won the fight with a body shot towards the end of round 6.
Castaño stepped up against former world title challenger and long-time contender, Michel Soro. Castaño won a close fight by split decision (115-113, 115-113, 112-116). The judges seem to prefer Castaño's activity and consistency over Soro's calculated pressure, who admitted he had started slow in a post-fight interview. Two months after the fight, Castaño said that Soro's promoter, Univent, had yet to pay most of his purse.
After Demetrius Andrade vacated his WBA (Regular) title, the WBA elevated Castaño to regular champion. Shortly thereafter, the WBA ordered a fight between Castaño and WBA (Super) champion, Erislandy Lara.
