Franco Stupaczuk and Miguel Yanguas arrived in Italy as the No. 6 and No. 7 seeds. They leave in the last 16. Jerónimo González and Lucas Campagnolo dismantled the pairing in straight sets — the standout result of a day that otherwise ran to seed at the top, and one that home favourite Giulia Dal Pozzo answered by winning twice to reach the semi-finals.
Jerónimo González / Lucas Campagnolo 6-4, 7-6 Franco Stupaczuk / Miguel Yanguas
This is the upset of the day. González (No. 14) and Campagnolo (No. 21) were not supposed to be the better team here — Stupaczuk and Yanguas are ranked eight and fourteen places above them respectively, and were seeded to go deep. Instead the underdogs controlled the terms of the match from the first exchange.
The first set went 6-4. The second refused to break, and it was González and Campagnolo who held firm in the tiebreak to close it out 7-6 and avoid a decider. Winning the tight set, rather than surrendering it, is what separated the two teams on the day.
The consequences run beyond one match. A last-16 exit is a heavy points loss for Stupaczuk and Yanguas at a Major, and it blows open a section of the men's draw that was expected to funnel a seeded team into the quarter-finals.
Nuria Rodríguez / Giulia Dal Pozzo 6-4, 0-6, 7-6 Carolina Orsi / Patricia Llaguno
Dal Pozzo, the Italian, gave the home crowd first a scare and then a celebration. She and Nuria Rodríguez took the opening set 6-4, then were bagelled 6-0 in the second, handing it over without winning a game. The response was the point of the day: they held their nerve through a deciding-set tiebreak to win it 7-6.
It was the first of two wins on the afternoon for the pair, and the volatility of the scoreline — dominant, then dominated, then ice-cold in the breaker — set the tone for a run nobody in the draw had priced in.
Nuria Rodríguez / Giulia Dal Pozzo 3-6, 6-3, 6-2 Sofía Araújo / Claudia Fernández
The bigger scalp came in the quarter-final. Dal Pozzo (No. 50) and Rodríguez, well outside the seeds, knocked out No. 6 Claudia Fernández and No. 8 Sofía Araújo — a pairing ranked comfortably inside the world's top ten.
They started slowly, dropping the first set 3-6. From there the match turned decisively their way: 6-3, then 6-2, with the underdogs growing into the rallies as the seeded pair's level fell away. Dal Pozzo is into the semi-finals on home soil, the story of the women's draw.
Arturo Coello / Agustín Tapia 6-1, 6-1 David Gala / Enzo Jensen
No drama at the top. The world No. 1 seeds needed barely an hour to see off David Gala and Enzo Jensen (No. 59), conceding just two games across the match and never letting their opponents settle at the net. A routine, efficient statement of intent.
Gemma Triay / Delfina Brea 6-1, 6-1 Patricia Martínez / Claudia Escacena
The women's top seeds were equally untroubled. Triay and Brea dispatched Patricia Martínez and Claudia Escacena 6-1, 6-1, matching Coello and Tapia's economy and moving through without expending anything they will miss later in the week.
With both No. 1 seeds cruising and the men's draw reshaped by the Stupaczuk-Yanguas exit, tomorrow's headline belongs to Dal Pozzo and Rodríguez, who carry a home crowd and two upset wins into the semi-finals.
