João Fonseca, an 18-year-old Brazilian tennis player ranked 57th in the ATP, made a notable debut at Wimbledon 2025. He won his first-round match against British player Jacob Fearnley, ranked 51st, in straight sets 6-4, 6-1, 7-6(5), marking his first Wimbledon main draw victory and becoming the youngest male player to win at Wimbledon since Carlos Alcaraz in 2011. Fonseca then advanced to the third round after defeating American Jenson Brooksby, ranked inside the top 101, with a 6-4, 5-7, 6-2, 6-4 victory. This win ended a 15-year drought for Brazilian men reaching the third round at Wimbledon and made Fonseca the youngest Brazilian to enter the ATP Top 50, reaching 48th place and surpassing Gustavo "Guga" Kuerten's record. In the third round, Fonseca faced Chilean qualifier Nicolás Jarry, ranked 143rd but a former top 20 player, who had made a comeback victory over eighth seed Holger Rune. Jarry defeated Fonseca 6-3, 6-4, 3-6, 7-6(4), eliminating the Brazilian from the tournament. Jarry advanced to the fourth round for the first time in his career, where he is set to face British player Cameron Norrie, the last remaining Briton in the singles draw. Norrie recently reached the fourth round after a five-set win over Jarry. Fonseca's performance at Wimbledon has been widely praised, highlighting his power, athleticism, and composure, and he is regarded as a promising young talent in tennis.
