Who are the 8 youngest players in the Top 50?
Eight players. Eight dazzling trajectories. And one certainty: tennis has rarely seen such a density of young talents capable of breaking the codes so early.
In this year-end ATP ranking, two teenagers break into the world's top 50, both already crowned with titles in 2025.
At the forefront of this revolution: João Fonseca, 19 years old, the Brazilian phenomenon who has become one of the circuit's number 1 attractions.
1. João Fonseca – 19 years and three months: the Brazilian cyclone
Fonseca only needed a spark to set the circuit on fire: a first title in Buenos Aires in February, then a second at the ATP 500 in Basel indoors.
Starting from 145th place, he finishes 24th in the world.
Many already see him in the top 10. Others imagine even greater things.
2. Learner Tien – 19 years and 11 months: the American revelation
Finalist in Beijing, winner in Metz, he finishes the year 28th in the world, driven by a rare audacity for his age.
3. Jakub Mensik – 20 years and two months: the slayer of Djokovic
His triumph will remain one of the highlights of 2025: Mensik wins the Miami Masters 1000 by defeating Novak Djokovic in the final.
A first major title and a turning point as well: he wraps up the season ranked 19th.
4. Alex Michelsen – 21 years and three months: the American method
No ATP title this year, but remarkable consistency. Michelsen reaches the quarter-finals in Canada, the round of 16 in Australia, and stabilizes in the top 40 (38th).
5. Arthur Fils – 21 years and five months: rage, talent, and frustration
His season was supposed to be one of confirmation... it turned into an emotional rollercoaster.
A terrible back injury at Roland-Garros sidelines him from the courts, after an impressive series of quarter-finals in Masters 1000 events.
He drops back to 40th place, but his potential remains intact: the Frenchman hasn't had his final say.
6. Carlos Alcaraz – 22 years and six months: the ogre remains a prodigy
He is no longer a "youngster," but remains incredibly precocious: six Grand Slam titles, Roland-Garros and US Open in 2025, three Masters 1000 titles, finalist at Wimbledon, return to the world No. 1 ranking.
Alcaraz continues to push the limits and reminds everyone that he is still the boss.
7. Holger Rune – 22 years and seven months: from genius to pain
A major title in Barcelona by defeating Alcaraz, then a serious Achilles tendon injury in October. Rune finishes the year 15th.
8. Ben Shelton – 23 years and one month: the American rocket
One of the biggest winners of 2025: entry into the top 10, a cannonball start, first Masters 1000 title in Canada, semi-final in Australia, first qualification for the ATP Finals...
Shelton closes the season ranked 9th, with the feeling that his potential is immense.
