The first Aussie man since Lleyton Hewitt to break into the top 10, de Minaur launched his charge up the world rankings last year when he knocked over Novak Djokovic on his way to helping Australia reach the semi finals of the United Cup team event.

Alex de Minaur dominates Tomás Etcheverry 6-1, 6-4 to level United Cup tie against Argentina at Sydney's Ken Rosewall Arena, but the well-credentialed doubles pair Ellen Perez and Matt Ebden are defeated to hand Argentina a 2-1 overall victory.
