In one of the most historic results in French Open history, Brazilian teenager Joao Fonseca came back from two-sets down to beat 24-time Grand Slam champion Novak Djokovic.
Fonseca became only the second player to turn around a two-set deficit against the world number one, delivering on his extreme promise in 4h53m.
Djokovic's loss to a man 20 years his younger means a fresh grand slam champion will be crowned in Paris next weekend.
Fonseca's greatest weapon is his forehand, which he hits with more power than anyone else on the men's tour.
Conditions played a role as Djokovic outlasted Fonseca, who showed nerves of steel late in the match.
The Brazilian teenager struck the lines often enough through the back end of the fourth set to push Djokovic into a fifth, and then broke his serve again at 5-5 to seal the win.
