Franco Stupaczuk and Miguel Yanguas were the highest-ranked pair to fall today, and they fell early. Jerónimo González and Lucas Campagnolo beat the world No. 6 and No. 7 in straight sets to headline a round of 16 that kept turning against the seeds. Nuria Rodríguez and Giulia Dal Pozzo went further still, carrying an upset run all the way into the women's semi-finals.
Jerónimo González / Lucas Campagnolo 6-4 7-6 Franco Stupaczuk / Miguel Yanguas
On paper the ranking gap read like a mismatch. Stupaczuk and Yanguas sit sixth and seventh in the world; González and Campagnolo, fourteenth and twenty-first. On court it inverted.
González and Campagnolo pressed the drive side early, took Yanguas out of his rhythm and broke to close the first set 6-4. The second tightened into a tiebreak. Stupaczuk and Yanguas needed it to force a decider and could not convert, and the underdogs held their nerve to take it 7-6. Two sets, no third act.
The result blows a hole in the men's draw. Stupaczuk and Yanguas leave without the run their seeding demanded, and González and Campagnolo advance into a quarter-final with the higher seeds cleared out ahead of them.
Nuria Rodríguez / Giulia Dal Pozzo 6-4 0-6 7-6 Carolina Orsi / Patricia Llaguno
Giulia Dal Pozzo, the Italian ranked fiftieth, gave the home crowd its result of the day — but she and Nuria Rodríguez had to survive a strange one. They won the first set 6-4, were handed a 6-0 bagel in the second, and still recovered to take the decider.
The middle set was a blackout: Orsi and Llaguno swept it without conceding a game, and the match looked to have turned for good. Rodríguez and Dal Pozzo steadied on serve in the third, dragged it to a tiebreak and edged it 7-6. It was the kind of set that decides tournaments in a partnership's memory.
The reward was a quarter-final against seeded opposition — one they would go on to win.
Nuria Rodríguez / Giulia Dal Pozzo 3-6 6-3 6-2 Sofía Araújo / Claudia Fernández
The seeding gap here was even wider: Claudia Fernández and Sofía Araújo ranked sixth and eighth, Dal Pozzo fiftieth. The favourites took the opening set 6-3 and controlled the early exchanges. Then the match slipped away from them.
Rodríguez and Dal Pozzo tightened the net and forced Araújo and Fernández to play from deep, winning the second 6-3 and running away with the third 6-2. Dal Pozzo's víbora off the revés side did the damage; Rodríguez covered the glass behind her. The seeds unravelled as the errors mounted.
Backing up an already-improbable round of 16 with a straight upset of a top-eight pair, Rodríguez and Dal Pozzo are into the semi-finals — the standout story of the women's draw and a live home threat.
Arturo Coello / Agustín Tapia 6-1 6-1 David Gala / Enzo Jensen
The world No. 1 pair did what favourites are supposed to do on days like this. Coello and Tapia never let David Gala and Enzo Jensen settle, breaking early in both sets and closing out a 6-1 6-1 win that barely troubled them. They advance untroubled and firmly on schedule.
Gemma Triay / Delfina Brea 6-1 6-1 Patricia Martínez / Claudia Escacena
The top women's pair matched the men's No. 1s stride for stride. Gemma Triay and Delfina Brea overwhelmed Patricia Martínez and Claudia Escacena 6-1 6-1, dictating from the middle of the court throughout. It was a statement of intent from the seeds who most want to avoid the chaos elsewhere in the draw.
Tomorrow the top seeds — Coello and Tapia, Triay and Brea — look every bit the class of the field, but the story to watch is Rodríguez and Dal Pozzo, whose semi-final places the tournament's most unlikely run one win from a final on home soil.
