Day 2 Winners: USA | Italy | Greece

Great Britain came into Day 2 with a 2-0 lead over the host nation after Cameron Norrie and Katie Swan posted straight-set wins on Day 1. Ranked No.98 and playing in the No.1 position for Great Britain, Dart seized her chance to clinch the tie by winning the coveted third point to build an unassailable 3-0 lead. 

"Maddy played really great tennis today and I had to work for it," Dart said. "First match of the year, I was really nervous, but the crowd were great."

No.180 Inglis was a late substitution in singles after Australian No.1 Ajla Tomljanovic withdrew from the match due to a left knee injury. With Captain Sam Stosur urging her on, the 24-year-old from Perth acquitted herself well and, after a slow start, consistently challenged Dart from the baseline. 

But Dart held her ground with clutch serving and a devastating day on her forehand. The 26-year-old Brit won 83% of her first serve points and was broken just once in the match. On her first match point, Dart fired her fifth ace of the match to take it after 92 minutes.

In the next match, Jason Kubler brought joy to Australian fans when he staged a remarkable second-set comeback to upset World No.27 Daniel Evans 6-3, 7-6(3), earning his nation its first win at the mixed-teams event.

In front of a raucous crowd on the Ken Rosewall Arena, Kubler stole the show, showcasing an abundance of quality and grit to fight past Evans in one hour and 51 minutes. The World No. 107 fired 11 aces and rallied from 0-5 in the second set, saving one set point at 4-5, before eventually sealing his victory in the tie-break.

After Kubler's heroics, Australia's vice-captain Sam Stosur reunited with her Olympic mixed doubles partner John Peers to finish on a winning note, defeating Harriet Dart and Jonny O'Mara, 7-6(4), 6-4 to give the home nation two points in the tie. 

The United Cup is a new mixed-teams event featuring 18 countries across Brisbane, Perth and Sydney. Played over two days, ties will be comprised of two ATP and two WTA singles matches and one mixed-doubles match.
