WATCH—Roger Federer prepares for Sunday start in London:
Stefanos Tsitsipas, who just won the Next Gen ATP Finals in Italy, says that he is still enjoying himself on court, but not too much.
“At the current moment, it's more work than fun. I did have fun—a lot of fun when I was young. I saw it as hobby. Now it's my profession, so I have to take it a bit more seriously,” Tsitsipas said. “And, of course, fun is there because without fun I'm probably going to stop in two years playing tennis. So I don't want that to happen."
The 20-year-old was also just voted Most Improved on the ATP Tour this season, getting inside the Top 15 with runs to the finals in Barcelona and Toronto, where he defeated Dominic Thiem, Alexander Zverev, Kevin Anderson and Novak Djokovic.
"There is fun but there is a lot of discipline, and there's a lot of working ethic on the court, strong mentality, which I have to always carry with me when I'm playing every single match," he said. "Because if I have too much fun, then the result or my performance might decrease. I don't want that.”
He soon earned another major milestone: winning an ATP title when he won Stockholm. While he wants to keep climbing the rankings, Tsitsipas also says behaving properly is just as important.
“It's better to be professional in what you do and be disciplined and concentrated every single time,'' Tsitsipas said.
Tsitsipas is currently the youngest player in the Top 20.
