World No. 66 Sierra clinched the win for her country in Group A with a 6-4, 5-7, 6-0 triumph over Jessica Bouzas Maneiro after Baez defeated Jaume Munar 6-4, 6-4 in the first match of the competition. Guido Andreozzi and Maria Lourdes Carle then downed Yvonne Carvalle-Reimers and Inigo Cervantes 7-6(6), 6-2 in the mixed doubles rubber to earn Argentina a resounding 3-0 triumph.<\/p>\r\n\r\n
The South American nation will next face top seeds and defending champions Team USA in their remaining Group A match.<\/p>\r\n\r\n
Argentina are hoping to advance from the group-stage play for the first time in three tournament appearances, and were aided in their opening win by its second-highest and highest-ranked players in the ATP Rankings and WTA Rankings, respectively. But Sierra's grit in particular was a highlight over 2 hours and 2 minutes, as she regrouped emphatically after losing a 5-2 lead in the second set.<\/p>\r\n\r\n
Sierra was two points away from a straight-sets victory twice in the second set, having 30-30 serving at 5-3, and on return at 5-4. But when all was said and done, she needed three sets to top the World No. 41 and earn her third career win over a Top 50 opponent. She lost just eight points in the third set after dropping five straight games to lose the second.<\/p>\r\n\r\n
Earlier, in the first match of the 2026 ATP Tour season, World No. 45 Baez defeated Munar to give Argentina a 1-0 lead. Making his debut at the mixed teams event, the 24-year-old Baez recorded a 6-4, 6-4 win against the Spaniard in one hour and 43 minutes in the Group A tie. With the victory, he improved to 2-0 in the pair\u2019s ATP head-to-head series.<\/p>\r\n\r\n
