Teenage wildcard Moise Kouame earned his first-ever tour-level win at the Miami Open on Thursday – and then immediately called the physio. The 17-year-old battled back from a set down to beat American ace Zachary Svajda 5-7 6-4 6-4. Kouame struggled physically and received an off-court medical timeout after winning the second set. The trainer also returned during some changeovers in the third set.

Kouame still battled through to win his first ATP Tour match. At 17 years and 13 days old, he’s also the youngest Miami Open men’s match winner, the youngest man to win a Masters 1000 match since Rafael Nadal in Hamburg in 2003, and the seventh-youngest man to get a match win at this level overall.

But the two-hour and 17-minute battle took its toll on the teenager. Kouame doubled over after shaking hands with Svajda and the umpire, and then called the physio again to receive treatment at his bench after the match.

Kouame had been cramping on match point and collapsed to the ground after clinching a three-set comeback victory. After he received more treatment, another trainer brought a wheelchair to the court, but the world No. 385 was able to walk off by himself, pumping his fists in celebration.

The French ace has also become the first man born in 2009 or later to win an ATP Tour match. Kouame will have a quick turnaround before his next match, as he is set to face No. 21 seed Jiri Lehecka on Friday. Kouame was originally scheduled to play his opening match on Wednesday, but the entire day was a washout, with all matches cancelled, so he has less time to prepare for the second round.

Kouame has been making waves on the lower tiers of the professional tennis circuits this year. He has already won two ITF titles in 2026 and also reached the semi-finals of the Lille Challenger. He made his ATP debut in Montpellier last month after getting a qualifying wildcard and advancing to the main draw, but lost his first-round match to Aleksandar Kovacevic.

The 17-year-old is currently sitting at a career-high ranking of No. 385 this week, but looks primed to crack the world’s top 320 thanks to his latest victory. Ahead of the tournament, Kouame told the ATP he wanted to reach the very top.

“My goal is to be World No. 1 and win lots of Grand Slam [titles]. This is what I am training for. Now it’s a dream, and I hope later it won’t be, but it will be real,” he said.

For now, Kouame has reached a huge milestone, winning his first tour-level match, and at a Masters 1000 event, no less. He has moved up to fourth in the Race to the Next Gen Finals – a year-end tournament for the best players aged 20-and-under on the ATP Tour.
