Australia's singles hopes are over at the ATP Tour's Miami Open, after Alex de Minaur and Chris O'Connell both fell in the round of 16.
A clash with Australian Open champion Jannik Sinner proved a step too far for Sydneysider O'Connell, who bowed out in a 6-4 6-3 defeat.
After a tight first set, de Minaur lost a roller-coaster clash with Hungarian hitman Fabian Marozsan 6-4 0-6 6-1.
