In 2024, Fonseca maintained his rapid pace of improvement. In January, he entered the ATP top 100 after a successful run at the Australian Open. Despite being eliminated in the second round, his victory over Russian Andrey Rublev, then ranked number 9 in the world, drew attention and demonstrated his potential.
Now, with his victory in Buenos Aires, he has reached 68th place in the world rankings, a total impressive jump of 31 positions in a single week.

Could João Fonseca be the next big name in Brazilian tennis?
Brazil has had tennis icons like Gustavo Kuerten, who won three Roland Garros titles and reached the top of the world rankings. Now, with the rise of João Fonseca, many experts wonder if he can follow a similar path and lead a new generation of Brazilian tennis players.
Fonseca's performance so far indicates he has the talent and mentality to compete with the best. His victory over Andrey Rublev at the Australian Open, along with his ATP title in Buenos Aires, are signs that he may be just beginning his successful career.
If he continues to improve on the circuit, he could inspire a new wave of young Brazilians to dedicate themselves to tennis and promote the sport in the country, just as Guga did in the 1990s and 2000s.
The growing demand for tennis courts in Brazil
The impact of João Fonseca's rise is already being felt across the national sports scene. With his and Bia Haddad's success, interest in tennis has grown among children and adults alike.
According to industry experts, there's a growing demand for classes and courts, reminiscent of the sport's boom during Gustavo Kuerten's era. As a result, many gyms and clubs are already reporting an increase in demand for practice spaces, demonstrating that the success of Brazilian athletes can fuel a new generation of tennis players.
Just as Ayrton Senna's era boosted interest in karting, and Guga's led to the growth of tennis in Brazil, the current era could represent a new cycle of expansion for the sport in the country. If this trend continues, Brazilian tennis could experience one of its most promising phases in the coming years.
