WATCH: The moment a world tennis pro was beaten by a kid wearing a hoodie.

It’s a moment this young boy will always remember, and one that Roger Federer would probably rather forget.

When World Tennis Champion Roger Federer stepped onto the court this week it’s likely that his aim was to win against Bulgaria’s Grigor Dimitrov. Not lose. And certainly, not to lose to a young boy.

In an exhibition match at New York’s Madison Square Garden this week the 33-year-old tennis pro, who is currently ranked number two in the world, was challenged by a young fan.

The boy, who casually stepped onto the court and took Dimitrov’s place, not only held a rally against Federer but beat him with a pretty impressive lob.

Take a look for yourself… 

Look’s like Federer may have finally met his match.
