The number-six seeds are gone. Franco Stupaczuk and Miguel Yanguas, the most pedigreed pairing in the bottom half of the men's draw, were beaten in straight sets by Jerónimo González and Lucas Campagnolo in the round of 16. It is the kind of early exit that quietly rewrites a bracket.
Jerónimo González / Lucas Campagnolo 6-4 7-6 Franco Stupaczuk / Miguel Yanguas
González sits at No. 14 and Campagnolo at No. 21. Across the net stood the No. 6 and No. 7 in the world. On paper this was a mismatch in Stupa and Yanguas's favour; on court it never read that way.
González and Campagnolo took the first set 6-4 and refused to blink when it mattered most. The second went to a tiebreak, and it was the underdogs who held their nerve through it, closing out 7-6 to win in two. Campagnolo's work off the glass on the revés side kept the rallies alive long enough for González to dictate from the middle.
For Stupaczuk and Yanguas, a high seeding came with the expectation of a deep run, and the round of 16 is not where that story was supposed to end. Their exit blows the bottom quarter wide open for the survivors.
Nuria Rodríguez / Giulia Dal Pozzo 6-4 0-6 7-6 Carolina Orsi / Patricia Llaguno Zielinski
This one swung violently. Rodríguez and Dal Pozzo took the opener 6-4, then were handed a bagel in the second, losing it 0-6 without finding an answer to Orsi and Llaguno's tempo.
The decider went the distance and into a tiebreak. Dal Pozzo, ranked 50th and carrying the home crowd, steadied the pair when the match was slipping away, and they edged it 7-6. A messy, three-set survival — but a survival.
Nuria Rodríguez / Giulia Dal Pozzo 3-6 6-3 6-2 Sofía Araújo / Claudia Fernández
The bigger scalp came hours later. Araújo (No. 8) and Fernández (No. 6) were the seeded pair; Dal Pozzo, at No. 50, was the lowest-ranked player on the court. The result did not respect any of that.
Rodríguez and Dal Pozzo dropped the first set 3-6, then turned the match on its head, taking the next two 6-3, 6-2 as the seeds' error count climbed. It is a second straight three-setter for the pair on the same day, and it carries them into the semifinals — the run of the women's draw so far, and a genuine home story.
Arturo Coello / Agustín Tapia 6-1 6-1 David Gala / Enzo Jensen
No drama at the top. The world No. 1 pair dismissed Gala and Jensen (No. 59) 6-1, 6-1 in a tidy hour's work, never broken and never threatened. The bandeja-and-vibora pattern through the middle was relentless. Coello and Tapia move on without expending anything they will miss.
Gemma Triay / Delfina Brea 6-1 6-1 Patricia Martínez / Claudia Escacena
The top women's seeds matched the men's No. 1 line for line. Triay and Brea handed out a 6-1, 6-1 beating to Martínez and Escacena, controlling the net and giving their opponents nothing to build on. Efficient, emphatic, and entirely expected.
The semifinals now pit the dominant top seeds — Coello-Tapia and Triay-Brea — against a draw that has lost some of its biggest names. The standout question heading into tomorrow is how far Dal Pozzo and Rodríguez can push their giant-killing run on home soil.
