Joao Fonseca has been on fine form this season which has seen him win three titles. He arrives in Florida with a high confidence. However, he’s aiming to work on two crucial parts of his game to be able to go far in the tournament.
The 18-year-old star began the season winning the ATP Challenger in Canberra. He then won his first match at the Australian Open. He has since won two titles, including his first ATP title in Buenos Aires. However, he hit a hard rock in Indian Wells. He succumbed to a 4-6, 0-6 defeat against eventual champion Jack Draper in the second round.
He took the lesson from his early elimination to sign up for the Challenger in Phoenix. There, he polished his errors and made sure he excelled beyond doubt. He showed his talent in the Coachella desert defeating Alexander Bublik 7-6(5), 7-6(0) to win the title. It was his third title in three months.
Since the win, he has relished to go back to the ATP Tour. The teenager was asked about what he aims to improve in his game ahead of the Miami Open. Fonseca revealed that he wants to be solid on serves and be aggressive on the court.
I wanted to be more solid on my serves and be aggressive at the same time. In the final, I didn’t have this opportunity, but I am trying to focus on this; on being more solid and aggressive, hitting the lines. I couldn’t do this against Draper in Indian Wells; the first set was very level, and we were both nervous. But then in the second, he broke my serve in the first or second game, and he attacked more than I did, and I couldn’t play my tennis, but these things happen. He has more experience; I have only been on the circuit for two years.
Joao Fonseca told Gill Gross
Fonseca’s debut win in Indian Wells and success in Phoenix saw him climb 20 places in the ATP rankings. The Brazilian currently seats as World No. 60 and is expected to continue his rise at the Miami Open.
Joao Fonseca says his coach has been helping him deal with pressure
Joao Fonseca has been the most famous youngster in the circuit this season. The 18-year-old star first made a name for himself at the Next Gen ATP Finals last December, where he won the title. After that, he defeated Top 10 star Andrey Rublev in the first round of the Australian Open. He has been trying to deal with pressure and expectations since then and says his coach has been helping him with that.

My coach and I have a saying that goes: ‘Pressure is a privilege.’ Pressure will always be there, and so will expectations. That’s why you have to stay focused and surround yourself with people who can help you, and that’s what I’m doing now. Surrounding myself with people who keep me a bit away from the media because they always create many expectations and pressure, and remaining focused on yourself.
Joao Fonseca said
Also, winning the Argentina Open made him very popular in his home country. The Brazilian teenager defied all the odds in the final by defeating fan favorite and Argentine Francisco Cerundolo.
Joao Fonseca to face Learner Tien in the first round of the Miami Open
Joao Fonseca will aim to get back to winning ways in the ATP Tour. The World No.60. was handed a wildcard for the Miami Open and will be playing at the event for the first time in his career. He is set to face a tough American youngster, Learner Tien, in the first round. Tien has also enjoyed a good run this season, especially at the Australian Open.

Fonseca will hope to defeat the American and get into the second round where he will face French Ugo Humbert. If he does beat the Frenchman, he is likely to play the 10th seed Alex de Minaur in the third round.
