Andy Roddick says that ATP's top four of Novak Djokovic, Rafael Nadal, Roger Federer, and Andy Murray have widened the gap between themselves and the rest of the tour. Djokovic, Nadal and Federer have combined for 30 Grand Slam titles since 2003 Wimbledon. Murray has yet to win a major, but reached the 2011 Australian Open final, as well as the semis of the three other majors last year.

But it’s cyclical. A couple years ago it was only two guys and now its four guys. Can it be six guys, sure? Can it go back to two, sure? After ‘06 I was not one of the guys, and then for an eight-month stretch in ‘09 I was one of the guys. I think guys can come in and out, but as we stand, those are the four best."—Matt Cronin
