Alexander Zverev may have chosen to skip the Next Gen ATP Finals in Milan after qualifying for the real deal in London, but that doesn't mean he's not supporting the inaugural event. The 20-year-old jetted to Italy to play in an exhibition match against alternate Stefanos Tsitsipas on Tuesday.

He even took advantage of the new changeover coaching rule to make fun of Marcelo Melo.

Zverev thrilled the crowd with his appearance, got to experience all of the new rule changes and walked away with a win.

In London, he's been drawn into the Boris Becker group with Roger Federer, Marin Cilic and Jack Sock.
