João Fonseca (joaoffonseca) went on to win the tournament and, in doing so, became the third-ever 18-year-old to win the prestigious event, with only Jannik Sinner and Carlos Alcaraz before him. The Brazilian hotshot built on his triumph in Saudi Arabia with a run to the second round of the 2025 Australian Open, where he won his first duel with a top 10 player in world number nine Andrey Rublev. In the latest milestone of his sensational rise, Fonseca secured his maiden ATP Tour title in Buenos Aires, and in style as one of the youngest champions in ATP Tour history. Fonseca overcame three of Argentina's home hopes en route to the final, going on to defeat Argentine no. 1 Francisco Cerundolo in straight sets for a fairytale first title of his senior career. As he continues to cause a stir, here's what else you should know about the Brazilian hot shot. #ACADEMIABSB #reading #leitura #studygram #joaofonseca #tenisbrasil
