 The same is true of male players.For singles tennis, both men and women ranked outside of the world top 40 or so and inside the top 180 or so will compete in both the top and second tier tour events.For male players, those ranked outside of the top 180 will then compete on both the ATP Challenger Tour and ITF Men's Circuit, while most players ranked outside the top 400 or so must compete on the ITF Men's Circuit.
