Franco Stupaczuk and Miguel Yanguas are out. The No. 3 seeds fell 6-4, 7-6 to Jerónimo González and Lucas Campagnolo in the round of 16, the day's clearest crack in the men's draw. It strips the top half of one of its expected quarter-finalists before the tournament reaches its business end.
Jerónimo González / Lucas Campagnolo 6-4 7-6 Stupaczuk / Yanguas
Ranked 14 and 21, González and Campagnolo were the lower pair on paper by some margin — Stupaczuk sits sixth, Yanguas seventh. On court the gap never showed. The winners controlled the drive side and took the opener 6-4 without facing real pressure on serve.
The second set tightened, and Stupaczuk and Yanguas forced a tiebreak. González and Campagnolo held their nerve to close it 7-6 and seal the straight-sets win. Campagnolo's work off the glass repeatedly reset points the seeds thought they had already won.
This is the sort of result that reshapes a quarter. With the No. 3 seeds gone, the section opens up — and it sends an in-form González–Campagnolo pairing into the last eight with momentum.
Nuria Rodríguez / Giulia Dal Pozzo 6-4 0-6 7-6 Carolina Orsi / Patricia Llaguno
Nuria Rodríguez and home favourite Giulia Dal Pozzo survived a wild round-of-16 tie against Carolina Orsi and Patricia Llaguno, winning 6-4, 0-6, 7-6. The middle set was a bagel — Orsi and Llaguno reeled off six straight games to level — but it proved a blip rather than a turning point.
The decider went the distance. Rodríguez and Dal Pozzo edged the tiebreak 7-6, riding the home crowd behind Dal Pozzo through the closing exchanges. After being blanked in the second, the response spoke to their nerve.
Nuria Rodríguez / Giulia Dal Pozzo 3-6 6-3 6-2 Sofía Araújo / Claudia Fernández
Hours later, the same pair went one better. Rodríguez and Dal Pozzo backed up the R16 escape by ousting a seeded partnership — Claudia Fernández, ranked sixth, and Sofía Araújo, eighth — 3-6, 6-3, 6-2 to reach the semi-finals. Dal Pozzo is ranked 50; it is comfortably the biggest win of the pairing's run.
Araújo and Fernández took the first set 6-3 and looked the steadier team early. The momentum flipped after the interval. Rodríguez and Dal Pozzo won nine of the last eleven games, closing 6-3, 6-2 as the seeds' error count climbed under sustained pressure from the back of the court.
It is a landmark result for Dal Pozzo, an Italian into the last four of her home Major. For a seeded partnership expected to contend, the early exit dents both the ranking math and the seeding logic of the bottom half.
Arturo Coello / Agustín Tapia 6-1 6-1 David Gala / Enzo Jensen
The world No. 1s barely broke stride. Arturo Coello and Agustín Tapia dismantled David Gala and Enzo Jensen 6-1, 6-1, conceding just two games on their way into the quarter-finals. Both sets followed the same pattern: an early break, then a serene hold from the front of the court.
Tapia's bandeja was a metronome and Coello closed points at the net with his customary weight. There is little to read into beyond confirmation that the favourites are moving through the gears.
Gemma Triay / Delfina Brea 6-1 6-1 Patricia Martínez Fortún / Claudia Escacena
The top women's pair matched them for ruthlessness. Gemma Triay and Delfina Brea beat Patricia Martínez Fortún and Claudia Escacena 6-1, 6-1 to reach the quarter-finals, never letting the tie settle into a rhythm their opponents could use.
The picture entering the quarter-finals is one of order at the top and disruption just beneath it: Coello–Tapia and Triay–Brea look imperious, while the exits of Stupaczuk–Yanguas and the Araújo–Fernández seeds hand Rodríguez and Dal Pozzo a genuine path deep into the draw.
