The last two decades of tennis have certainly been monopolized by two men, albeit separately, i.e. a certain Pete Sampras and his successor Roger Federer. Sampras dominated the hard courts and grass courts during the 1990s, with Andre Agassi giving him close competition on a consistent basis.
And the 2000s have been dominated by a man with probably the largest fan-following in tennis history, i.e. Roger Federer.
However, in between the building of these two dynasties there was a window of opportunity for a few pretenders to the throne to gain their share of the spoils.
This was well-utilized by the likes of Lleyton Hewitt, Andy Roddick, Marat Safin, and even Goran Ivanisevic towards the end of his love affair with Wimbledon.
This is a look at the tried-to-be's, the want-to-be's, and the should-have-been's of men's tennis, who are likely to retire without a Grand Slam title to their names. This slide show is in no particular ranking order.
