US Open Boys Championship at NYC along with Jack Sock. Video Interview.
I was really surprised to find out he comes from Arlington, VA too. Today I got to play a couple sets both with and against him. He'll be America's next Andy Roddick in a few years.
It was an amazing opportunity for me to play against him and his brother Nikita. They could be the next Bryan brother doubles pair, who knows =)
Best of luck for the rest of your tournaments this year, Denis!
