its Alex Bogomolov Jr.
he's Alex Bogomov Jr. and he looks like a little Lleyton, and plays like him too. He immigrated to the USA from Russia with his family, and is listed as RUS for the Open. The crowd loved him, he's the little engine that could. It would be great if nice things happen for him, and since its a mouthful to shout "go Bogomolov" we all just yelled go "jr." You would hope that he gets through to play AA in the 3rd round.
