ATP Buenos Aires: Cerundolo Stuns Zverev, Fonseca Makes History At Argentina Open

Francisco Cerundolo stunned World No. 2 Alexander Zverev 3-6, 6-3, 6-2 in the Buenos Aires quarterfinals, marking the biggest win of his career. His previous-best career win by ranking came against a No. 3-ranked Casper Ruud at another clay-court event, Barcelona, in 2023. In another quarter-final match, Brazilian teenager Joao Fonseca saved two match points in a thrilling 3-6, 6-4, 7-5 win over Mariano Navone to become the youngest ATP clay-court semifinalist since Carlos Alcaraz four years ago. Pedro Martinez advanced to the semifinals after receiving a walkover from Lorenzo Musetti.
