Can you imagine being 21 and putting up that fierce of a fight against 24-time grand slam champion Novak Djokovic?

That's Carlos Alcaraz for you.

He's already won the US Open, the French Open, and Wimbledon, and now adds a silver medal from the Olympics to his trophy room.

Djokovic was in tears by the end of the match and so was Alcaraz, but for a different reason.

But when you're already playing like this at 21, the world is your oyster.
