It seems like only yesterday that he was a little boy, embarrassing his father during his first mayoral inauguration speech. And it was only yesterday, almost, that he embarrassed himself, getting thrown off the Duke golf team for being a pain in the ass and having his suit against them settled in a fanciful legal opinion. But little Andrew Giuliani, son of Rudolph, is advancing, and has won his first pro-am golf tournament, taking the 94th Met Open Thursday at Ridgewood Country Club by a single stroke. “He has his father’s drive — and his winning ways,” says the Giulianifiliac New York Post. Indeed he does, but congratulations anyway.
