How Moise Kouame, 17, is proving age is just a number

Moise Kouame overcame a player more than twice his age Tuesday at Roland Garros, where he beat former World No. 3 and Grand Slam champion Marin Cilic in straight sets, producing a result that felt symbolic as much as historic.

When Kouame was born in March 2009, Cilic was already established on the ATP tour. The Croatian was a three-time tour-level titlist, who was ranked World No. 18 and had made his major main draw debut more than two years earlier, at the 2007 Australian Open. For most young players, that gap can feel overwhelming. But the 17-year-old never looked bothered by it. The Frenchman stepped onto one of the sport’s biggest stages and played with the composure of someone who belonged there.

“I didn't care about his age, I just wanted to give him shots that were as complicated to play as possible,” Kouame said. “For some, the age factor may play a role, but not for me. I tried to focus, not to think about it, because in the end, when you're on court, you don't think about your age or what you're going to eat. You think about what you have to do to win.”

Until recently, Kouame was primarily competing on the ATP Challenger Tour and in ITF World Tennis Tour events. The Frenchman began his 2026 season by winning his first two titles on the ITF World Tennis Tour in France and backed up those triumphs by coming through qualifying to make his tour-level main-draw debut at the Open Occitanie in Montpellier. In March, the 17-year-old made his ATP Masters 1000 debut at the Miami Open presented by Itau. Just last month, after competing at the ATP Masters 1000 events in Miami and Monte-Carlo, he won an M25 event in Santa Margherita di Pula, Italy.

The Frenchman has made his debut at the highest level in the sport, competing alongside the very best players in the world. But the Frenchman has also put in the hard yards on the ITF World Tennis Tour, winning three tournaments to help earn his wild card into his home major. Kouame has approached each step with composure, and now he is into the second round of a Grand Slam tournament.

“The experience I got from Miami, Monte-Carlo, and also Montpellier probably helped me,” Kouame said. “In Montpellier the atmosphere was good. As far as the tennis level is concerned, I felt rather relaxed, rather serene. I could feel good with my serve, with my forehand.

"I knew that if I lost the match, it wouldn't be stress, really. I just wanted to go in and have fun, and that's what I managed to do. Even if I hadn't won [my first-round match], I would still have had fun at least. After all, that's the most important thing.”

As the spotlight grows bigger, Kouame keeps carrying himself like a player still focused more on the work than the noise around it. Now he will face Adolfo Daniel Vallejo in the second round at Roland Garros. Should the 17-year-old win, he will become the youngest man in the third round at a major since Rafael Nadal at 2003 Wimbledon. Kouame would also become the fifth-youngest man in the Open Era at Roland Garros after Michael Chang (16) in 1988, Kent Carlsson (16) in 1984, John Alexander (16) in 1968 and Bjorn Borg (16) in 1973.

“I'm of course looking for more, Kouame shared. “All the practice worked. The most important [times] are ahead. I am focused on recovering and being ready as much as possible for the next round.”
