Velasco started his career in the youth system of
Independiente, having joined the club in 2012. He was promoted into their first-team, aged sixteen, towards the end of the
2018–19 campaign, with the winger initially appearing as an unused substitute for a
Copa Sudamericana second stage encounter with
Rionegro Águilas on 21 May 2019. He was again on the bench for the second leg on 28 May, with Velasco subsequently making his professional debut at the
Estadio Libertadores de América; replacing
Jony in added time. Sixteen appearances later, Velasco scored his first senior goal in the Sudamericana away to
Fénix in
Montevideo. ==International career==
