The Argentine tennis team has announced its squad for the fourth edition of the United Cup, to be held next January. The team features the tennis player Sebastián Báez (45th in the ATP ranking) and the player Solana Sierra (66th in the WTA ranking), who had an excellent season.
In men's singles, there will be no second player, while in women's singles, the second player will be Mariah Lourdes Carlé (128th). In men's doubles, Guido Andreozzi (33rd in the doubles ranking) and Nicole Fossa Huergo (110th in the doubles ranking), who recently became an Argentine citizen, will play for the country.
The team also includes the experienced Marco Trungelliti (136th), who recently started representing Argentina, and Solana Sierra, whose 2025 season was simply fantastic: the 21-year-old from Mar del Plata won two WTA 125 tournaments and two W75s, and also reached the quarter-finals of Wimbledon, breaking into the top 100 and becoming the best Argentine female player in the ranking.
For the fourth time in the history of this tournament, Argentina will try to get past the group stage for the first time, having been eliminated at this stage in the previous two years (2023 and 2025) and having failed to qualify for the 2024 tournament.
The team's squad was presented as quite surprising. In men's singles, instead of Báez, who is in poor form (he has dropped to 45th place, winning only four matches since May), Trungelliti was called up. The 35-year-old player, born in Italy but who became an Argentine citizen this week thanks to his grandparents, had the best season of his career, winning two Challenger tournaments.
The women's singles squad looks more logical. Sierra, the best Argentine player, and Carlé, whose best result of the year was winning the WTA 125 tournament in Rende, Italy, in partnership with Georgian tennis player Ekaterine Gorgodze, will form the main force.
The women's doubles pair was also formed by experienced players: Nicole Fossa Huergo and Guido Andreozzi. Fossa Huergo, the second best Argentine player with vast experience playing for the national team, including the United Cup and the Billie Jean King Cup, will partner with Andreozzi, the current champion of the Argentina Open and the ATP 250 in Bastad, Sweden.
