Kouame’s 6-3 7-5 6-3 6-2 6-6 (10-8) defeat of Vallejo came in front of a partisan Parisian home support at Roland Garros, who cheered the local boy to the very last point as he defied Vallejo’s charge.
The 22-year-old is ranked 71st in the world – compared with Kouame’s 318 listing – and recovered from a narrow second set defeat to storm back level from two sets down, then moving to the verge of victory at 5-3 in the fifth, only for his teenage opponent to break back.
Whether it was Kouame’s energy first, or that of the crowd, the crescendo almost spilled over to the following game, as the crowd had to be settled and nearly impinged on points.
Vallejo was not perturbed and produced his own fire in searing Parisian heat to keep Kouame and his feverish following at bay.
Kouame held serve with the aid of two stunning backhands down the line that brought the crowd to their feet and took the match to a tie break – the youngster responded with a showmanship and swagger that suggests a star may just have been born.
His feat, matching that of Nadal at Wimbledon 20 years ago, was pushed to a one-sided finale by another backhand in his final break of serve in the longest game of the match before holding his own game.
The 10-point match tie-break that followed saw Kouame storm to the first five points, only for his plucky Paraguayan opponent to once again prove his own resilience by drawing level at six points each.
By 7-7, Kouame somehow produced his fastest serve of the day for an ace that was only the latest in a long line of party tricks.
The backhands and drop shots wowed all the way, but it was a cross-court forehand that broke Vallejo to move to 9-8. Then came the moment to hold his serve, as well as his nerve.
As the home crowd and their newfound star soaked in the moment – it would appear a new Parisian love affair has just begun.
Kouame is the fifth-youngest player to make it to the third round at Roland Garros since the Open Era began in 1968. The youngest remains American Michael Chang, who achieved the feat aged 16 in 1988.
Kouame will face Chilean Alejandro Tabilo, the world number 36, in the next round.
