Made in Miami: The Rise of Jakub Mensik

Tennis is a sport driven by generations, and a generation is defined by its players. The current generation may currently be dominated by names like Carlos Alcaraz and Jannik Sinner, but with the crown comes a target. 21-year-old Czech Jakub Mensik is aiming for the throne.

Mensik is one of the sport’s most tantalizing prospects as his form in 2026 reaffirms. He began the year by cruising to the fourth round of the Australian Open, until an abdominal muscle injury stopped a promising run. A month later, he beat then-world No. 2 Jannik Sinner in the quarterfinals of the Qatar Open. By late spring, he had broken through at Roland Garros, knocking off two top-12 players and emerging talent João Fonseca en route to his first Grand Slam semifinal appearance.

Now up to a career-high No. 16 in the world, Mensik is solidifying himself as one of the sport’s brightest stars. But the breakthrough that set it all in motion came in Miami.

On March 20, 2025, Mensik was a 19-year-old kid ranked outside of the top 50. He was set to play Roberto Bautista Agut in the first round of the Miami Open, but decided to opt out due to inflammation in his right knee. Unable to walk or run, Mensik decided he would withdraw from the tournament, and so he walked down to the referee’s office to break the news, only to find the referee absent.

Mensik visited the trainer instead, and thanks to some painkillers, he was able to hobble onto the court.

“Somehow I won the first round and basically then I had one day off, which of course, for my knee was much better. Day by day, the knee was getting better and with that also my game,” Mensik said.

His task was tall in the second round. Mensik drew No. 6 seed Jack Draper, who was only a week removed from his maiden Masters 1000 title at Indian Wells.

Unphased, Mensik dispatched the lefty in two tiebreaks with the help of 21 aces. He cruised through the third round in straight sets before a walkover in the Round of 16 granted him a quarterfinal matchup with No. 17 seed Arthur Fils, a fellow star in the making. Mensik’s momentum was real. He cruised past Fils 7-6 (5), 6-1 and into his first career ATP Masters 1000 semifinal. After the win, Mensik said that it was “the biggest result so far in my career.”

Suddenly, Taylor Fritz was the only thing standing between Mensik and the final of an ATP Masters 1000 tournament. Seeded No. 7, Fritz’s game was, and still is, astonishingly comparable to Mensik’s: big serve, heavy groundstrokes and aggressive baseline play.

Mensik didn’t break Fritz once during a three set, two-and-a-half-hour marathon that ended 7-6 (4), 4-6, 7-6 (4) in Mensik’s favor. Thanks to clutch play in tiebreaks and 25 aces, Mensik was miraculously into the Miami Open final.

His opponent was Novak Djokovic, a childhood idol and one of the greatest to ever play the sport. The affair was delayed five and a half hours due to rain, leaving Mensik to sit with his thoughts before the biggest match of his life.

When the sky finally cleared, so did Mensik’s psyche. The teenager produced a magical performance inside Hard Rock Stadium as he passed the final test, 7-6 (4), 7-6 (4) in two hours. After entering at No. 54 in the world, Mensik became the second youngest Miami Open champion and the lowest-ranked player to ever win the tournament. His ranking shot up 30 places to No. 24, and he pocketed $1.1 million. But the praise and respect from his lifelong idol were worth infinitely more.

“Never really happy to lose, but he’s one of the very few players that I would be happier to lose to, to be honest,” Djokovic said after the contest. “ He was training at my club in Belgrade, and to see his development and evolution is really great, amazing.”

To think Mensik almost withdrew ahead of the first round.

Mensik’s triumph was truly unbelievable and a story only tennis could tell. Playing through injury, he strung together seven wins (with one being a walkover) while only dropping two sets. Even more remarkably, Mensik took the semifinals and final by winning all four sets in tiebreaks, edging two top-10 players by the thinnest of margins. In total, the Czech went 7-0 in tiebreaks across the tournament.What Mensik displayed in 2025 in Miami is exactly what has allowed him to succeed since: an explosive serve, a deadly backhand and the innate ability to deliver when the stakes are highest. The Miami Open wasn’t just a title run, but a glimpse of what was to come.

It would be wrong to say a star was born the day he lifted the Miami Open trophy, because the star was born 19 years earlier. Instead, when Jakub Mensik earned the Miami Open title, a star found its place in the constellation of men’s tennis.
