French teenager Moïse Kouamé made the perfect start to his French Open career with a 7-6 (4), 6-2, 6-1 win over Marin Cilic.
The 17-year-old Kouamé won one day after 39-year-old Frenchman Gael Monfils made his last appearance at Roland Garros.
The teenager raised his arms in triumph after defeating the 37-year-old Cilic, who won the 2014 U.S. Open, finished runner-up at two other majors, and reached the French Open semifinals in 2022.
The ATP Tour said No. 318-ranked Kouamé became the first man born in 2008 or later to win a Grand Slam match.
In March, he became the youngest winner in Miami Masters history when he beat Zachary Svajda in the first round — earning a congratulatory message from Djokovic.
