Few teenagers have walked onto Court Suzanne Lenglen and owned it the way Moise Kouame did on Thursday. The 17-year-old from Sarcelles, playing only his second Grand Slam match, came back from 5-2 down in the fifth set to defeat Adolfo Daniel Vallejo of Paraguay 6-3, 7-5, 3-6, 2-6, 7-6 in a match that lasted nearly five hours.
The win sent the Paris crowd into a frenzy. It also sent Kouame into the history books.
By reaching the third round at Roland Garros, Kouame became the youngest man to advance this far at any Grand Slam since Rafael Nadal did it at Wimbledon in 2003. He is also the youngest to reach the third round at the French Open since Michael Chang, who was 16, accomplished the feat in 1988.
A comeback that defied the odds
Kouame entered the deciding set with momentum, but Vallejo quickly flipped the script. The Paraguayan raced to a 5-2 lead and appeared set to close out the match. Kouame refused to fold.
Drawing energy from a crowd that had been roaring his name all night, the teenager clawed his way back and forced a tiebreak. Vallejo then went on a six-point run from 1-6 down to make things uncomfortable, but Kouame held his nerve and closed out the tiebreak 10-8.
The match had everything. Five sets, momentum swings in both directions, a raucous home crowd, and a finish that will be replayed for years.

Kouame arrived at Roland Garros as an unknown
Context makes the achievement even sharper. Kouame entered the tournament ranked 318th in the world, receiving a wildcard to compete. He had dropped two straight matches on the ATP Challenger Tour before arriving at Roland Garros. Nothing about his recent form suggested a deep run at a major was coming.
His first-round win over former US Open champion Marin Cilic, played on Court Simonne-Mathieu, was already historic. That result made him the youngest man to win a Grand Slam singles match since 2009 and the youngest to reach the second round at Roland Garros since 1991.
His second-round win raised the stakes further. Two show courts, two wins, and two records that will stay with him for life.
Kouame works with Richard Gasquet, himself a former prodigy who reached a career high of No. 7 in the world. That coaching relationship appears to be shaping a player who already shows the mental steadiness that usually takes years to develop.
What comes next for the French sensation
Kouame now faces Alejandro Tabilo in the third round. The Chilean, seeded 16th, received a walkover after Valentin Vacherot withdrew with a left-foot injury. Tabilo arrives well-rested while Kouame will need to recover from nearly five hours on court.
Still, the draw has opened up in a way that gives Kouame a plausible path to Philippe Chatrier, the main show court at Roland Garros. He said playing there would mean everything to him.
His two wins already came on two of the tournament’s biggest stages. A third round appearance on Chatrier would complete a French Open debut that no one saw coming and that no one in Paris will forget anytime soon.
