These top players are household names. Federer's fame even transcends sports.
But there are some new faces racing up the ATP rankings. No, we're not talking about perennial also-rans like Jo-Wilfried Tsonga or Tomas Berdych, guys who have been knocking at the door of the elite for years and now find the window of opportunity closing.
This list does not include the likes of David Ferrer and Richard Gasquet, consistent players past their prime.
This power ranking is about those who burst on the scene in the last five years and continue a steady climb toward the top. Although their names may be unfamiliar, these guys have the tools to one day reign atop the ATP.
