For a chance to play the US, Germany, or the Czech Republic in a play-off to advance to the semi-finals, Great Britain, Spain, and Australia compete.

Lleyton Hewitt, the co-captain of Australia, has been accused of "throwing him under the bus," according to Nick Kyrgios.

In order to prepare for the Australian Open, Kyrgios withdrew from the United Cup mixed teams competition, and the 27-year-old was dismayed by his co-captain's public response.

Hewitt expressed his frustration at the lack of communication and claimed to be uninformed of Kyrgios' withdrawal.

Kyrgios tweeted about whether Tomljanovic will be treated differently when she pulled out of her match against Dart.

"I worry if Sam Stosur, Australia's co-captain, would humiliate her in the same way."
