As Joao Fonseca’s first full season on the ATP Tour approached its end, he clinched the biggest title of his career so far.
Fonseca won a maiden ATP 500 title at the Swiss Indoors in Basel, beating Alejandro Davidovich Fokina in the final to hold the trophy aloft.
The Brazilian became the first from his country to claim a tour-level crown above ATP 250 level since Gustavo Kuerten’s Masters triumph at the Cincinnati Open in 2001.

At 19 years and 60 days of age, he also became the youngest South American to win titles on multiple surfaces in a single season, surpassing Argentinian tennis great Juan Martin Del Potro, who achieved the feat aged 19 years and 315 days.
Now ranked 28th in the world, Fonseca will enter the Paris Masters seeking to record a perfect ending to his debut trip around the tour, which he says has been an ’emotional’ one.

Speaking to the media after his triumph in Basel, the young star said: “It’s very special, and even more so here in a tournament that in Brazil we call Roger’s home. Roger’s tournament.”
Roger Federer won the Swiss Indoors a record ten times throughout his career, three-peating at the tournament on two separate occasions.

“Roger is my idol, which makes it even more special. It’s a tournament that I have wanted to play in since I was a kid. Switzerland is a super cool place.
“When you’re playing at this level more and more, you’re getting into it now. You’re playing in these increasingly bigger tournaments and the players are getting more difficult.
“It’s getting harder to get good results, so having these consistencies after a very… I would not say up-and-down year, but some downs, and I kept fighting, and kept working.

“Obviously, it is my first year playing in the big tournaments. A very emotional year. It’s a year of very important titles for me.
“I’m happy to be closing the year with a flourish. My last goal was to be top 32 by the Australian Open.”
