MELBOURNE, Jan 23 (Reuters) - Alex ‌de Minaur underlined his credentials as the leading home hope at the Australian Open on Friday, ‌securing a 6‑3 6‑4 7‑5 win over American 29th seed Frances Tiafoe to reach the ‌fourth round for a fifth successive year.

The sixth seed's efficient victory ensured he became only the second Australian man in the professional era to go on such a streak after John Newcombe, who reached the last 16 at the tournament from 1969-76.
