Overview
- Sebastián Báez upset world No. 6 Taylor Fritz 4-6, 7-5, 6-4 to give Argentina the opening point and claim 90 ATP points with his second career top-10 win.
- Coco Gauff overpowered Solana Sierra 6-1, 6-1 to level the tie.
- Gauff then partnered Christian Harrison to defeat María Lourdes Carlé and Guido Andreozzi 6-4, 6-1, clinching the Group A series for the United States.
- The tie was played at Perth’s RAC Arena, and the Americans entered as the defending champions.
- To win the group, Argentina would need Spain to sweep the U.S. 3-0; otherwise its path relies on being one of the two best second-placed teams.
