Alex de Minaur and Alexei Popyrin have been left celebrating new career landmarks with their double assault on the Japan Open title in Tokyo.
The two 24-year-old Sydneysiders both powered into the quarter-finals of the ATP 500 hard-court event at the Ariake Coliseum on Thursday by defeating South American opposition.
De Minaur took out another diminutive battler, Argentine Diego Schwartzman, 6-0 7-5 while Popyrin fought from a set and a break down to beat Chilean Cristian Garin 4-6 7-6 (7-3) 6-2.
