Brazilian tennis prodigy Joao Fonseca, 19, is set for a second-round clash with Carlos Alcaraz at the Miami Open after defeating Fábián Marozsán in three sets. The rising star recently pushed world number-two Jannik Sinner to tiebreaks at Indian Wells. Fonseca feels fully recovered from a back injury and aims to reach the top five.
Joao Fonseca, a 19-year-old Brazilian tennis player, conducted media rounds at Hard Rock Stadium in Miami Gardens ahead of the Miami Open. Dressed in a bluish On T-shirt, Whoop fitness band, and Rolex watch, he displayed confidence during interviews and social media segments, including attempts to balance a banana and naming young ATP 1000 winners. Observers noted his assured presence as he navigated the bustling environment, with staff and reporters drawn to him after two years on tour and a recent ranking surge despite a lower back injury months earlier. Fonseca stated, “I think I’m understanding a little bit more about how the top players play—not technically, but mentally,” highlighting his growth in handling key points and match openings. At the BNP Paribas Open in Indian Wells weeks prior, he challenged Jannik Sinner in the round of 16, taking both sets to tiebreaks. “I knew there wasn’t much of a weakness that I could try to put my power against,” Fonseca said of Sinner, emphasizing the need for consistency against such opponents. Last year, after breakthroughs at the Australian and Miami Opens, he secured two tour titles. Now feeling “100%,” he focuses on improving his game, mentality, and physique for a top-five ranking, while managing tour downtime with games like Catan. Tournament director James Blake has called for Fonseca to play on the stadium court throughout his run, given his popularity among South Florida's Brazilian community. Having won his first-round match against Hungary’s Fábián Marozsán in three sets, Fonseca embraces the electric Miami atmosphere, saying, “I am prepared.”
