Youngster Mihailo Topic rises to the occasion

A lot happened in Belgrade over the weekend during the first leg of Novak Djokovic's Adria Tour. Amidst outrage over the lack of masks and Dominic Thiem winning the trophy, one ball boy got his moment to shine.

The ball boy is Serbia's Mihailo Topic, who celebrates his 11th birthday on Tuesday. On Saturday, Viktor Troicki called him onto the court while he was down against Djokovic, and Topic didn't hesitate, executing a sly forehand drop-shot winner.

Topic is well-known in the Serbian tennis world.

The youngster trains at the Novak Tennis Center in Belgrade has been in Djokovic's inner circle for years.

And has shared a court with the world No. 1 before.

Before Topic got to be a big part of the Adria Tour, he took photos with many of the stars including Jelena Jankovic:

Alexander Zverev:

And Dominic Thiem:

It's obviously too soon to tell, but Topic might become a household name for longer than one point in the years to come.
