Rio was in full swing, but high-profile homegrown youngster Fonseca was knocked out in the first round, completely missing the style of last week's victory on tour.

Last week, Fonseca, 18 years and 5 months old, defeated local star F-Cirondello on the turf of Argentina to win his first tour title.

He has been in the spotlight since winning the New Force Finals last year. This year's Australian Open defeated Rublev, the quarterfinalist of the former tournament, which is impressive. The outside world has given high praise, believing that he can catch up with Akasina in the future and become the new post-00 third person.

What does the future hold for Fonseca? Let's compare the achievements of other players on one list: Fonseca became the 10th youngest player to reach a tour final since 2000 by reaching the final in Buenos Aires alone. The other players are:

Nadal 17 years and 7 months

Nadal, who is talented and knows how to become famous early, occupies two places in the top three of this list, and the time span is nearly half a year apart, which has to be admired that he was really born for tennis.

Kei Nishikori 18 years and 1 month

The former glory of Asia was also unbelievable, and he eventually lived up to expectations, finishing runner-up in the Grand Slam and Masters. He was also shortlisted for the Comeback of the Year award after his comeback last year, and we look forward to continuing to deliver on his talent."

Alcaraz 18 years and 2 months

Acre's first final on the Tour came at Umag, where he set off his record for a high title in a Tour final.

Fritz 18 years and 3 months

The American brother also made the list, he debuted at almost the same time as Paul, Tiafoe and others, and in terms of current career achievements, he has won Grand Slam and year-end runner-up and Masters championships, and he is also the highest among the all.

Gasquet 18 years and 3 months

The French veteran was also one of the proper talents back then, but he debuted at the same time as Nadal, and in the end he was far from his friend's career achievements. All of his titles have come in the 250 tournament, which is a bit shabby for a player who has reached the semi-finals of a Grand Slam.

Murray was 18 years and 4 months

Murray, who reached a Grand Slam final at the age of 21, reached his first tour final three years ago and had a successful career after retiring last year.

Mensik 18 years and 5 months

The Czech, who reached the final in Doha at the start of last season, turned out to be a dark horse with a lot of colour, and it was widely expected that he would eventually surpass his compatriots Lehecka and Mahachi.

Federer 18 years and 6 months

As strong as the Swiss king, he can only be at the bottom of this list of 10 people, and his first Grand Slam was "belated" at the age of 22.
