Rising Spanish teenager Rafael Jodar made a stunning French Open debut, defeating American Aleksandar Kovacevic 6-1, 6-0, 6-4 while dropping just five games. Jannik Sinner now faces a new potential challenger as Jodar's performance equals Novak Djokovic's 2005 debut as the best in tournament history. The 19-year-old is on a remarkable trajectory from No. 707 to No. 29 in just one year.

Jodar enters the clay-court Grand Slam with serious momentum, having won 16 of his past 19 matches. His recent achievements include a clay trophy in Morocco, semifinals in Barcelona, and a quarterfinal run in Madrid cut short by Sinner. The absence of injured defending champion Carlos Alcaraz and French hopeful Arthur Fils further opens the field for Jodar's breakthrough.

In other Paris action, 2015 champion Stan Wawrinka exited in his 21st and final French Open appearance, falling to Dutch qualifier Jesper de Jong. Only one seeded player lost Monday as American Ben Shelton, No. 5 seed, advanced in straight sets. Jodar sits in the bottom half of the draw, meaning a potential showdown with Sinner would have to wait for the final.
