Joao Fonseca defeated Federico Coria 2–6, 6–4, 6–2 in the second round of the ATP 250 Buenos Aires tournament on clay on 13 February 2025, confirming his status as the clear pre-match favourite. Coria, competing at home, began strongly to claim the opening set, but Fonseca's superior consistency asserted itself in the second and third sets as the Argentine's level dropped. The Brazilian teenager recovered from the early setback to control the latter stages of the match, securing a commanding victory that underscores his upward trajectory on the ATP circuit. The result advances Fonseca deeper into the Buenos Aires draw, where the home crowd's initial support for Coria proved insufficient to sustain his challenge.
