There’s a particular kind of pressure that comes with being a promising young tennis player these days. It’s no longer enough to be good, or even exceptionally good. You have to be deemed the future of the sport—the next big [insert number here]—often before you’ve had much time to figure out who you are in the present. As a result, every breakthrough is treated as a coronation, while every setback is a referendum on whether any hype bestowed upon was justified.
Jakub Mensik is in a particularly unique position. The Czech player has already accomplished things that many professionals spend their careers chasing. In March 2025, at just 19, he won the Miami Open, defeating his childhood idol Novak Djokovic in the final to claim his first ATP title. It was a remarkable achievement, made even more so by the fact that he had nearly withdrawn from the tournament before his opening match because of a knee problem. Instead, he went on to beat a string of top players, including Jack Draper, Arthur Fils and Taylor Fritz, before delaying Djokovic’s 100th career title.
Mensik’s success has earned him plenty of attention, though perhaps not quite as much as some of his peers. He’s frequently compared to João Fonseca, the young Brazilian whose enormous popularity at home and growing international profile have made him one of tennis’s most talked-about prospects. Much of that comparison centers on the attention each of them receives, with Fonseca generating considerably more buzz despite Mensik having a stronger resume thus far. Mensik, for his part, doesn’t seem particularly interested in keeping score.
“If someone my age does something big, obviously, to stay competitive, you want to do it too,” Mensik says. “But I don’t think you can spend your life looking sideways at what everyone else is doing. There are so many young guys coming up, so someone is going to win something every week and if you react to everything you’ll go crazy.”
It’s a pragmatic outlook from someone who has barely entered his twenties. But Mensik, who turned 21 in September, has never quite seemed his age. At six-foot-five, with a formidable serve and a generally measured demeanor, he has the presence of someone who has been doing this for much longer than he actually has. Even his answers tend to be unusually thoughtful for a player so early in his career.
Or perhaps, he suggests, we’re giving him too much credit.
“I don’t know if I would describe myself as mature,” he says, laughing. “Maybe I just don’t talk that much.”
Keep reading for more on how Mensik is navigating the expectations that come with early success, the challenge of sustaining it, and his determination to build a career on his own terms—despite the oft-cited comparisons to Djokovic.
