Fonseca continues to explode: four wins in a row to win the championship and become one of the top 10 youngest tour winners!

Overwhelming! Fight to fame is known to the world! This morning, Beijing time, Brazilian teenager Fonseca defeated Cerendro at the Buenos Aires Championship at the age of 18 years, 5 months and 26 days, and won his first tour championship trophy, becoming the youngest South American champion in the tour era since 1990.

So, who are the youngest champions in the ATP Tour era? Where does Fonseca fit on this list?

Let's take a look at the youngest champion of the ATP Tour era (since 1990):

1. Hewitt, 1998 Adelaide, 16 years, 10 months and 18 days

Former world No. 1 and year-end No. 1 youngest record holder Hewitt was beaten by Arca in 2022, but still holds the record for the youngest tournament winner on tour. At the age of 17, he won the championship in his hometown in one fell swoop, which drove the local audience into a frenzy.

2. Andrei Medvedev, Genoa 1992, 17 years, 9 months and 21 days

3. Andrei Medvedev, 1992 Stuttgart, 17 years, 10 months and 19 days

4. Andrei Medvedev, 1992 Bordeaux, 18 years and 20 days

The player, who shares the same surname as the current Russian Mei Zong, is best known for serving as the background emperor for Agassi to win the Grand Slam at the 1999 French Open. In fact, this player looks old, but he is a talented player who has made a name for himself at a young age. At the age of 18, he had already won three tournaments, but unfortunately he did not get a corresponding good result at the major level.

5. Kei Nishikori, 2008 Deira Beach, 18 years, 1 month and 19 days

The former Light of Asia also has a place on this list. At the start of the season at Deira Beach, he was a smiling leader, and although he did not win a Grand Slam or Masters in the future, he was able to finish runner-up in both places, and he is the only Asian male player to have a bracket.

6. Nadal, 2004 Sopot, 18 years, 2 months and 12 days

Finally it's the turn of the Spaniards! Although he could only finish sixth in Sopot, Nadal then went on to win the clay trio and the French Open in one fell swoop.

7. Hewitt, 1999 Dela Beach, 18 years, 2 months and 15 days

Or Hewitt! Or Deira Beach! Hewitt made the list again and proved his talent, but unfortunately he met Federer in the middle and late stages of his career, otherwise his career could have been even more successful.

8. Alcaraz, 2021 Umag, 18 years, 2 months and 20 days

Aka is also on the list, and the following year he won the US Open, making the leap from his first tour title to his first Grand Slam title in just one year.

9. Zhang Depei, 1990 Toronto, 18 years, 5 months and 7 days

Another genius! To date, he still holds the record for the youngest men's singles Grand Slam title!

10. Fonseca, 2025 Buenos Aires, 18 years, 5 months and 26 days

Fonseca is ranked 10th on this list, and since 1990 only Hewitt, Andrei Medvedev, Kei Nishikori, Nadal, Alcaraz and Zhang Depei were younger than him when they won the title. Judging by the fact that all six players have broken into the top four in the world in the highest rankings, the Brazilian's future is limitless.(Source: Tennis Home Author: Luo Cheng Qiye)
