In Sydney, Diego Schwartzman is lifted by teammate Guido Pella after both won their singles matches against Team Croatia to clinch Group E for Argentina, advancing their country to the quarterfinals.

Madison Keys had reason to be pleased after defeating Australian Samantha Stosur, 7-5, 6-3, to move into the last eight in Brisbane. The American's first victory in four meetings with the 2011 US Open champion set up a clash with red-hot Danielle Collins, who has dropped just three games in emphatic wins over Elina Svitolina and Yulia Putintseva.

World No. 1 Rafael Nadal departed Perth with more than just a medal. After leading Team Spain to the top of Group B and trip to the knockout phase in Sydney, the 19-time major champion received his 2019 ATP Stefan Edberg Sportsmanship Award in an on-court ceremony.

Despite losing her 2020 debut to Collins in Brisbane, Svitolina stuck around to take in local culture and support boyfriend Gael Monfils. Here, the Ukrainian had the opportunity to visit one of the city's graffiti walls.
