'Demon' drags hosts Australia into United Cup quarters

Also progressing into the last eight of the season-opening 18-team ATP-WTA event were Belgium and the Czech Republic, but Italy bowed out. Hopes are high at home that De Minaur, fondly known as "Demon", can go deep at the Australian Open starting this month and he served warning with a 6-4, 6-1 win over the 18th-ranked Mensik. That drew Australia level in the tie against the Czech Republic and De Minaur then paired up with Storm Hunter as they won the mixed doubles rubber in straight sets to progress.
