Another marquee tie at the 2026 United Cup will see Group A’s Team USA face Argentina in a night-session clash at Perth’s RAC Arena. The Americans arrive with a formidable lineup headlined by Taylor Fritz and Coco Gauff, both poised to make an early statement. Coming off solid campaigns in 2025, the duo will be eager to open the 2026 season on a strong and confident note. Moreover, Mackenzie McDonald, Christian Harrison, Varvara Lepchenko, and Nicole Melichar-Martinez add much-needed strength to their lineup.
Meanwhile, Argentina, who have yet to make an impact at the mixed-team event, will be aiming to do so, and few opportunities come bigger than a clash against two-time champions USA. The South Americans draw strength from a balanced squad featuring Sebastián Báez, Marco Trungelliti, and Solana Sierra, among others, as they look to spring an upset.

USA vs Argentina Head-to-Head
Adding another layer of intrigue to the tie is the fact that the two teams have never faced each other at the United Cup, leaving their head-to-head record locked at 0–0.
USA vs Argentina Prediction
American No. 1 and World No. 6 Fritz will take on Argentina’s Sebastián Báez in the men’s singles matchup. Fritz arrives in strong form after capturing two titles in 2025 and compiling an impressive 53–23 win–loss record. Báez, by contrast, endured a largely inconsistent season; despite lifting the ATP 500 title in Rio, the World No. 45 closed the year with a modest 17–24 record.
Fritz also holds a commanding 5–0 head-to-head record against the Argentine, placing him as a clear favorite heading into their upcoming clash. Gauff is also positioned as the clear favorite heading into her singles encounter. The World No. 3 closed the 2025 season with a strong 48–16 win–loss record and two major titles, including the French Open and the WTA 1000 event in Wuhan.

Sierra, meanwhile, arrives ranked No. 66 and on the back of a respectable 46–20 record last year and will be eager to test herself against one of the tour’s biggest names. Although their head-to-head stands at 0–0, Gauff’s superior ranking and big-match experience give her a decisive edge going into the contest.
Despite both sides boasting proven doubles specialists, World No. 15 Christian Harrison and World No. 18 Nicole Melichar-Martinez for the USA, and Guido Andreozzi alongside Nicole Fossa Huergo for Argentina, the tie may well be decided before the mixed doubles match comes into play.
Pick: USA to win 2-0.
